Interface Instrumentation Definitions

The new Interface Instrumentation Selection Guide is a great way to get started in choosing the right instrumentation for your next project or lab. To serve as additional resources, here are key instrumentation definitions that can also help you make the best decision regarding the type and model of instrumentation that will work best with your sensor.

Instrumentation Selection Guide Definitions

Excitation
A Wheatstone bridge-based sensor, such as a load cell, requires excitation voltage to operate. The excitation voltage is typically 10V; however, many instruments supply lower voltage, an 2.5V, 5V, and others. Since these sensors are ratiometric, Interface instrumentation devices are designed to pair with these types of sensor products.

Signals
The output signal from a load cell is expressed in terms of mV output per V of excitation, at capacity. For example, a 100 lb capacity load cell rated for 2 mV/V output will have 20mV output at 100 lb, when excited with 10V. Because the output signal is directly affected by input voltage, it’s important to maintain a stable excitation voltage, which our instrumentation does.

Signal Conditioners
A signal condition provides stable excitation voltage to the sensor and amplifies the low-level sensor signal to a high-level output such as +/-5V, +/-10V, 0-20mA, 4-20mA, 0-5V, or 0-10V.
Many of our products include filtering, which can help reduce noise in the output signal.

Data Acquisition Systems
A complete data acquisition system consists of DAQ hardware, sensors and actuators, signal conditioning hardware, and a computer running DAQ software. Interface provides DAQ instrumentation that are ideal for completing a sensor-based system. Many data acquisition systems require high-level inputs such as +/-10V and don’t work very well with low level mV signals. Interface instrumentation solutions do work well with DAQ systems. The DAQ doesn’t necessarily supply a stable excitation voltage like the Interface sensors do.

Interface Modules
An interface module converts the low-level mV/V sensor signal to a digital format that can be transmitted to a computer, (PC or laptop). Popular interface modules provide USB, wireless USB, or Bluetooth data transmission. Software is normally provided and allows data display, logging and graphing. The interface modules are commonly used when data needs to be logged to computer and you are not using an existing data acquisition system. The interface module advantages over standard data acquisition is ease of use and they are normally plug-n-play. Considerations when selecting this type of instrumentation include bit resolution, number of channels, sample rate, software features and type of output.

Indicators
Interface indicators provide stable excitation voltage and converts the sensor signal to a digital display. Commonly available features include analog or digital output, selectable digital filtering, peak and valley monitoring and set point outputs. Things to consider when selecting an indicator are internal sample rate and update rate of analog output.

Wireless Telemetry System (WTS)
Wireless is very popular today. Interface’s Wireless Telemetry System is easy-to-use providing wireless data communication between a load sensor and a receiving indicator. The WTS is capable of receiving multiple inputs and is fully compatible will all Interface force sensors. The WTS comes calibrated, tested and ready-to-run. The charge lasts up to three months using AA batteries.  You can see the complete WTS and Bluetooth Telemetry System comparison here.

When selecting the type of instrumentation you need to pair with your measurement device, some additional things to consider are power supply requirements, amount of filtering, fixed or adjustable filtering, input range, scalability and zero adjustment range. Our instrumentation can accommodate these requirements. To get started on picking the instrumentation solution that fits your requirements, go to the Interface Instrumentation Selection Guide.

We’ve provided a quick visual reference of Interface’s instrumentation types and correlating models.

Load Shackles 101

A load shackle is a u-shaped, load-bearing connecting device designed to be used with a removable pin. Load shackles can be used in a number of different rigging and load securement applications to provide sensor technologies in the connection of different types of lifting slings, chains or ropes to an object or to each other.  A load shackle is essentially the installation of a load monitoring pin into the shackle body allowing you to replace existing rigging hardware with a load cell for force measurement and weighing data.

Load shackles are rugged in design and are used to provide accurate and reliable measurement of tensile loads, as well as support applications for harsh and challenging environments. The industries that most regularly take advantage of our load shackles include industrial, aerospace and defense, agriculture, and construction. Applications for lifting, moving and weighing objects can be monitored as well as optimized for performance using load shackles. They are often designed into engineered structures or for use with cranes, winches or other robust lifting mechanisms.

Interface offers a wide variety of load shackle designs for different environments and force measurement needs, ranging from 2.2K to 2205K lbf. Our load shackles come in both cabled and wireless, as well as environmental resistance options including flameproof and IP67. Visit our overview here.

Load shackles come in many standard shapes and sizes, including customization options to meet a specific design or use requirement. Some of our shackles are exclusively designed to meet the needs of applications in hazardous environments like the oil and gas industry, or marine industry where they’ll be submerged in water during testing and for continuous use, or in areas with high heat and flames. Some of our most popular load shackles are listed below:

WTSSHK-B Wireless Crosby™ Bow Load Shackle  – Suitable for use in a wide range of industrial and marine weighing applications, these load shackles are robust, reliable and easy to install. The unique telemetry housing is manufactured from tough high-performance polyamide resin making it strong yet light, resulting in a better-balanced load shackle when compared to others available on the market.

ISHK-B Bow Type Crosby™ Cabled Load Shackle – The Interface range of ISHK-B load shackles are designed for lifting and weighing in rugged or harsh environments, including submersible applications. The shackle pins are forged from high tensile stainless steel to 6.5 MT (14.3K lbf) and high tensile carbon steel from 9.5 MT (20.9K lbf), and are machined to an exacting specification. The basic shackle uses the Crosby G2130 (1 to 25 MT / 2.2K to 55.1K lbf), G2140 (40 to 120 MT / 88.2K to 265K lbf) and GN Rope H10 (150 to 1K MT / 331K to 2205K lbf).

Flame Proof Bow Type Crosby™ Cabled Load Shackle – The Interface range of flameproof load shackles is designed for lifting and weighing in rugged or harsh environments, and also meet the requirements for operation in Zone 1 and 2 hazardous areas. The shackle pins are forged from high tensile stainless steel and are machined to an exacting specification. The basic shackle uses the Crosby G2130 (1 to 25MT or 2.2K to 55.1K lbf) and G2140 (40 to 400MT or 88.2K to 882K lbf) series.

Load Shackle Application:

Load shackles are commonly used in the construction industry to measure heavy machinery. For cranes outfitted with a lifting attachment such as a claw, a tension sensing load shackle is used on the pulley mechanism to measure the weight lifted by the crane. The tension sensor can provide real-time data to the construction crew to help monitor the lifting process and provide the operator with the information necessary to refrain from lifting weights that are too heavy for the crane to handle. If the claw arm lifts more than the crane is able to withstand, the attachment could break off, or worse, the crane could topple over.

In a recent example, Interface’s customer used a WTSSHK-B Wireless Load Shackle connected to load-bearing strings and a WTS-BS-1-HA Wireless Handheld Indicator to gather data. The customer was able to successfully lift and read the weight (wirelessly) on a handheld display while the material was being relocated.

Interface Load Cell Indicators

At Interface, our claim to fame is that we offer the most accurate and reliable force measurement devices on the market, from load cells to torque transducers and everything in-between. However, no test is complete without the system used to gather the data to evaluate performance results. That’s why we provide a wide variety of instrumentation solutions that include signal conditionersoutput moduleshigh speed data loggersportable load cell indicators, and weight indicators to complete any testing system.

Among the Interface instrumentation products, the most frequently purchased with a force measurement devices are our load cell indicators in various models including handheld, digital, wireless, multichannel, programmable, output modules, analog and bidirectional.

What is a load cell Indicator?

A load cell indicator is a high-accuracy device connected to the output of a load cell to amplify and display the value of the measured load force and weight. Load cell indicators are often needed where the force, load, or weight measurement needs to be visually displayed for the user and displaying the results on a PC is not feasible or desired in the testing environment. For example, testing in the field or confined spaces can make it impossible to connect directly to a PC. In these situations, indicators are used to quickly review and capture force data in real-time.

A few key benefits of load cell indicators include that they provide stable excitation voltage and converts force measurement sensor signals to a digital display. Commonly available features include analog or digital output, selectable digital filtering, peak and valley monitoring and set-point outputs. Additionally, each load cell indicator can be used to connect to four (or more) digital load cells and can display individual readings or the sum of all connected load cells.

Need a load cell indicator?

Interface offers a wide variety of load cell indicators in multiple configurations. Interface indicators come in single to multi-channel weight transmitters and can be found in handheld and portable designs. Things to consider when selecting an indicator are internal sample rate and update rate of the output. A few of our most popular indicators include:

9890 Strain Gage, Load Cell, & mV/V Indicator

Load Cell Indicator Application Note

The application note below provides an example of the benefit of a load cell indicator in real-world use within the medical industry.

A pharmaceutical tablet producer wanted to monitor the forces applied by the tablet forming machine to understand the relationship between raw material, die set, forming force, and motor-cycle speed. The goal was to improve productivity and efficiency of the tablet forming process while reducing losses, such as cracked tablets or voids, by adding a dimension of feedback that could be used to assign specific press adjustment criteria for given inputs.

An Interface Model WMC Sealed Stainless Steel Mini Load Cell (10K lbf Capacity) was mounted in the section of the downward press bar. The machine was modified to accomplish this. The load cell was then connected to a Model 9320 Portable Load Cell Indicator to collect the needed data.

The indicator was selected as the data collection device because a laptop could have interfered with the test cycle due to space restrictions. The output of the load cell was connected to the 9320 Portable Load Cell Indicator and set aside so that the cable did not interfere with the cycle and no snagging would occur. A cable tie was used to stow aside the cable and to ensure there was enough clearance for the entire cycle.

After analyzing the data, the tablet producer was able to quantify adjustment levels by monitoring which forces produced the most optimal results for a given cycle speed, die set, and raw material. Productivity and efficiency were greatly improved by the enhancement of the data feedback.
