Demystifying Specifications Webinar Recap
Interface's Demystifying Specifications recorded webinar details product specification basics, key values, terms to know, how to read a datasheet, what specs matter most in force measurement, and commonly asked questions. For Interface, specifications are detailed descriptions that outline the characteristics, features, and qualities of our products, systems, or services. Throughout the webinar, Interface experts provide tips on what to consider for high-speed, durability, precision and speciality load cell, torque transducer, multi-axis sensor and instrumentation product requirements.

Load Cell Test Stands 101
Interface provides high-accuracy load cells, instrumentation and DAQ systems, software and accessories designed for use in various types of test stands. Load cell test stands are important devices for manufacturers and testing engineers who need to measure the force or torque applied to a object, test specimen, or product. They are typically made up of a frame, one or more load cells, software, and data acquisition instrumentation.

Understanding GUM and Measurement Uncertainty
GUM, the Guide to the Expression of Uncertainty in Measurement, defines terms and concepts related to uncertainty. GUM describes methods for uncertainty calculation, and offers guidance for reporting and the documentation of uncertainties in measurement results. Interface knows that understanding GUM and the adherence to good test and measurement practices are essential to minimize uncertainties and ensure reliable measurement results for every application. In addition, reducing uncertainty with regular calibration of testing devices and proper maintenance of the equipment go hand-in-hand with GUM.

The Rise in Digital Force Measurement Solutions
Digital measurement solutions have come a long way and are growing in use and popularity due to overall trends towards digital transformation and modernization of testing labs. Interface offers a host of digital instrumentation solutions and complete digital systems to easily integrate into your existing test infrastructure. The Interface Instrumentation Selection Guide is a useful resource to help in the selection of digital equipment.

Torque Transducers and Couplings are the Perfect Pairing
A torque transducer coupling is a specific coupling designed to facilitate the connection and torque measurement between a torque transducer and a rotating shaft, providing accurate and reliable torque data. Whenever you are selecting an Interface torque transducer, be sure to request or add the Interface couplings that are designed for that specific transducer model. It is especially important to review the couplings features that pairs with your specific transducer. They are designed to work together, and you risk any problems or potential transducer failure.

Shunt Calibration Resistors 101
Interface shunt calibration resistors, known as RCAL Resistors, are an accessory product. A shunt calibration resistor is a resistor that is connected in parallel with a measurement instrument to provide a known resistance value. The purpose of the shunt cal resistor is to calibrate the instrument to accurately measure the current passing through it. Shunt calibration resistors are often used with load cells to improve the accuracy and reliability of their measurements.

Load Cells Versus Piezoelectric Sensors
Load cells and piezoelectric sensors are used in all types of measurement applications. Interface load cells measure the amount of force or weight being applied to them. The amount of force is numerated by the capacity of the model design, such as 50lbf (pounds-force) or 5kN (kilonewton). Piezoelectric sensors work on the principle of piezoelectricity. They are made of materials that generate an electric charge in response to mechanical stress, such as pressure or vibration.

What is Moment Compensation?
Every Interface LowProfile™ load cell is moment compensated to minimize sensitivity to extraneous loads. Moment compensated load cells are designed to counteract the external forces or moments by using a configuration of strain gages and electronics that can detect and compensate for these forces. The strain gages are arranged in a way that allows the load cell to measure the force applied to it in multiple directions, and the electronics can then use this information to calculate the impact of external forces and moments on the measurement.

Hydraulic Press Machines and Load Cells
Load cells are commonly used in hydraulic presses to measure the force or weight of the load that is being applied to the press. Load cells are essentially transducers that convert a mechanical force into an electrical signal. Load cells play a critical role in ensuring the safety, quality, and efficiency of hydraulic press operations, as they allow operators to monitor and control the force being applied to the workpiece with a high degree of accuracy and precision.
