We have engineered sensor products used for civil engineering designs and infrastructures used in structural monitoring, vibrational monitoring, load bearing testing, tunnels, bridges, and road construction. The range of projects are broad, so we are highlighting a few below that highlight our capabilities when accuracy, quality and reliability matter in design, testing, construction, and assessing current and limitations for safety requirements.

Hydraulic Jacking System Testing

An equipment manufacturer needed to test their hydraulic jacking system’s ability to lift heavy loads and objects, like a bridge during construction. They wanted to monitor the forces being applied to ensure the hydraulic jack is not only safe to use, but works well enough to avoid any potential structural issues. Interface’s 1200 Standard High Capacity Load Cell can be attached in between the hydraulic jack and a heavy load. The load cell measures the forces of the hydraulic jack as it lifts the load cell located in between the jack and the object. With the 9890 Strain Gage, Load Cell, & mV/V Indicator, the customer is also able to see the results in real-time. Read more here.

Aerial Lift Overload Control

A manufacturing company for aerial lifts wanted to test its self-propelled boom lift to ensure it can operate at heavy capacities when in use, and at different angles. They also wanted to prevent any accidents in case of a lifting overload, for the safety of any working individual who uses it. Interface’s solution was to attach the 3A160 3-Axis Force Load Cell to the bottom of the bucket of the boom lift. The multi-axis sensor provides high accuracy results, which were displayed using the 920i Programmable Weight Indicator and Controller in real time. The manufacturing company tested their aerial boom lifts and determined it was safely operable when maximum capacities has been reached in use. Read more here.

Truck Weighbridge Monitoring

A transportation company needed to record the weight or loads being carried by their vehicles. They would like a wireless weighing bridge that is able to transmit, log, and display the results in real time. Interface suggests installing multiple WTS 1200 LowProfile™ Load Cells under a weighbridge. When a truck drives over it, the load cells will transmit the force results wirelessly to the WTS-BS-4 Industrial Base Station connected to the customer’s PC with provided Log100 software. The WTS-LD2 Wireless Large LED Display can also display the weight inside for the driver to see in real time. The customer was able to measure, log, and graph the different loads their trucks carried wirelessly onto the weighbridge with success, providing for safe passage across transportation ways. Read more here.

Hydropower Turbine Generator Monitoring

A customer wanted to monitor and detect any turbine generator faults in their hydroelectric power plant located on a river. Interface’s solution was to use the T2 Ultra Precision Shaft Style Rotary Torque Transducer and attach it to the turbine generator with Interface’s Shaft Style Torque Transducer Couplings. When water from the river pushes through the penstock to the outflow, it moves the turbine blades, creating electricity through the generator shaft. Torsion measurements can be graphed and logged with the 9850 Torque Transducer and Load Cell Indicator catching any unusual fluctuations and vibrations. Using this solution, the customer was able to monitor, graph, and log the torque measurement results of the turbine generator. Read more here.

Bridge Seismic Force Monitoring

A customer wanted to monitor seismic activity that occurs to a bridge by using force sensors and then continuously monitoring bridge forces before, during and after earthquakes occur. The customer also preferred a wireless solution so they would not need to run long cables on the bridge. Using Interface’s LP Load Pin custom made to fit their needs along Interface’s WTS Wireless Telemetry System for continuous force monitoring the designed solution was able to take place without long cables. The solution allowed the customer to monitor continuous loads, log information to the cloud and review information. Read more here.

Choosing the Right Torque Transducer

Interface offers an extensive line of torque transducer models in different designs and capacities to fit all types of torque measurement testing requirements.  The first thing to understand when choosing the right torque transducer is how an actual torque transducer works in order to then determine the best type, style, model, mounting, capacity and special features for your requirements.

A torque transducer, like a load cell, consists of a metal spring element, or flexure. Strain gages are applied to the flexure in a Wheatstone bridge configuration. Torque applied to the sensor causes bending or shear strain in the gaged area, generating an output voltage signal proportional to torque.

To assist you in choosing the right torque transducer, get a copy of our Torque Measurement Primer for reference in your selection process.

Reaction or Rotary Type

There are also two different types of torque transducers: reaction and rotary. A reaction, also known as static, torque transducer measures torque without rotating, while a rotary torque transducer rotates as part of the system. A rotary sensor, also sometimes called dynamic torque, is merely a reaction sensor that is allowed to rotate. Normally, a reaction style sensor has a cable attached to it for supplying excitation voltage to the strain gage bridge and for output of the mV/V signal. Spinning of these sensors is prevented by the attached cable. To get around the issue of the attached cable, a variety of methods have been used for rotary sensors Some of those methods include slip rings, rotary transformers, rotating electronics, rotating digital electronics and radio telemetry.

Shaft or Flange Style

Torque transducers typically come in one of two major mechanical configurations, shaft or flange style. Shafts can be either smooth or keyed with keyed shafts coming in either single or double-keyed versions. Flange style sensors are typically shorter than shaft style, and have pilots on their flange faces as a centering feature.

Smooth shafts offer some advantages over their keyed counterparts, including more uniform introduction of the torque into the measuring shaft, ease of assembly and disassembly and zero backlash. A coupling designed for use with smooth shafts will have some method of clam ping to the shaft. This is commonly accomplished with split collars or shrink-disk style hubs. Shrink-disk style hubs usually include features to aid in their removal from the shaft.

Hubs for keyed shafts are simpler than those for smooth shafts and cost less but can suffer from wear due to backlash, especially in reciprocating applications. To prevent backlash, the hub must be installed on the keyed shaft with an interference fit, which is usually accomplished by either heating the hub before installation or pressing the hub onto the shaft.

Fixed or Floating Mount

There are also two main methods of mounting rotary torque transducers, fixed or floating. Fixed mount applies only to sensors with bearings and involves attaching the sensor housing to a fixed support. In floating installations the sensor is supported only by its drive and load side connections, which are typically single-flex style couplings. A flexible strap keeps the torque transducer housing from rotating. By definition, bearingless sensors are always floating mount.

Fixed mounting requires that the sensor housing have a means to attach it to the support. Sometimes the mount is an option on the sensor and sometimes the foot or pedestal mount is built as part of the sensor. The simplest fixed mount design sensors include a flat machined surface on the housing with threaded mounting holes. In fixed mount installations, double flex couplings must be used.

Capacity

Once you have determined the type, style and mount, how do you choose the right transducer for your project? One of the primary considerations is selecting the right capacity. On one hand, if you choose too large a range, the accuracy and resolution may not be enough for the application. On the other hand, if you choose too small a size, the sensor may be damaged due to overload, which is an expensive mistake. No manufacturer wants you to overload the sensor.

To select the proper size, first determine the amount of torque you want to measure. This can be easy or hard, depending on your application. An easy example would be a fastener torque application, where a certain amount of torque is to be applied to a fastener. A more difficult application might be trying to figure out how much torque is required for a new design wind turbine.

This is just a brief overview, there are many other variables to consider when choosing a torque transducer. To get a full rundown, check out our white paper Torque Measurement Primer. And as always, give us a call to speak directly with our applications engineers to learn more at 480-948-5555.

With more than 36,000 product SKUs in Interface’s extensive catalog, it can be a daunting task choosing the sensors that fit your exact needs. Fortunately, we’re here to work you through it! There is an abundance of content, including product brochures, white papers, case studies and application notes, for easy comparing of different product types and categories .

Interface Calibration 101

Calibration of force and torque sensors is critical to receiving accurate data from measurement testing.  Calibration is the comparison of the instruments output against the known standard of measurement. For a load cell, it is the comparison of the load cell output against the standard test loads.

The calibration ensures the sensor is performing accurately and set for ideal output based on the capacity and configuration of the design. A standard calibration tests repeatability and linearity, which are both used to determine the accuracy. Calibration tests are run to identify any potential measurement errors caused by zero offset, non-linearity, hysteresis, non-repeatability, and shifts from zero.

The team of calibration experts at Interface are specifically trained to provide this specialized service as part of our quality and lab standard requirements of operations. Interface is ISO/IEC 17025:2017 and A2LA Accredited for Torque and Force Calibration in accordance with the recognized International Standard ISO/IEC 17025:2017.

Interface certifies all our load cells with accredited calibration before releasing the product for shipment. Certificate information includes tabulated measurement variables data, zero balance, computed nonlinearity and hysteresis, and traceability statements. We are often recognized as the most complete calibration certification in the industry

In a recent customer survey, we found that one of the most important roles that Interface force measurement solutions play is for our calibration services. This is due to the accuracy, reliability, and dependability over long periods of time of the load cells we manufacture and service.

Why Calibrate?

Calibration is important based on many different factors, including continued performance, safety, and compliance with ISO or industry specific standards. Interface’s standard recommended calibration interval is to recalibrate every 12 months. The frequency of calibrations should be determined by the following use case factors that may affect measurement accuracy:

  • Measurement quality and allowable tolerance range
  • Level of stress to which the equipment is subjected
  • Stability of past calibrations
  • Required measuring accuracy
  • Quality assurance requirements

Recap of Latest Spin on AxialTQ Webinar

Interface recently hosted a new webinar in our ForceLeaders series that highlighted the revolutionary AxialTQ product.  The event reviewed the bearingless wireless rotary torque transducer design and detailed component specifications, why test engineers prefer the AxialTQ, and use cases for this precision measurement system.

If you were not able to attend the Latest Spin on AxialTQ event, you can watch the entire recording online here.

The revolutionary AxialTQ was first introduced in 2018. The design originated from the popular HRDT product that utilized a rotor stator gap design as a single component. After hundreds of users, we started the product engineering exercise to see how we could advance the soon-to-retire HRDT and evolve it into something that would perfectly fit current market conditions.

As technologies were changing testing protocols and requirements, such as for electric motors, alternative energy hardware, space vehicles and industrial machine automation, we wanted to add new functionality. Jay Bradley and the Interface engineering team began the process by looking at DIN size optimization, shorter stators, additional coupling options, advanced software configurations and simple “drop-in” replacement parts with a modular design.

After thousands of design hours and testing, Interface released the AxialTQ. The specialized product is a unique combination of accuracy, reliability and ease of use that redefines the standard torque measurement device in terms of function and durability.

Engineers prefer the new AxialTQ because of the time-proven sensing element with longer active area providing greater measurement sensitivity while being less vulnerable to shock loads.  The high-resolution digital electronics are state-of-the art. Uniquely, the large gap design up to 6 mm axial and 12 mm radial minimizes contact damage which is important at high-speed testing. It has 120-degree partial loop antenna on the stator to make installation easier.

Specialized design features of AxialTQ make it a great fit for test and production applications.

  • Crash-proof design for maximum reliability
  • Industry-leading gap to prevent damage to rotor stator at full speed
  • Simultaneous analog and digital outputs, enables real-time control and data collection
  • Interchangeable stators and output modules minimize parts inventory
  • Versatile design and wide range of configurations to match any application
  • Hardware is self-configuring
  • New advanced software with added features and logging capabilities
