How Does Tensile Testing Work?

/in

Interface supplies load cells for tensile testing. Tensile testing is fundamental in test and measurement. Load cells are commonly used in tension testing to measure and record the force or load applied to a specimen during the test. Tensile testing is used by researchers, testing labs, and engineers across industries including infrastructure, medical, manufacturing, aerospace, consumer goods, automotive, energy, and construction to measure stress, strain, elacity, fatigue and failure.

Are Load Cells Used in Vacuum Environments?

/in

Interface provides load cells thare can be used in a vacuum environment. However, not all load cells are created equal or suited for this specialized use case. Vacuum testing labs are used by a variety of industries, including aerospace, medical, and defense. These labs are common for material process testing and used in R&D. Vacuum testing helps to identify potential problems with products and materials before they are used in a vacuum environment. Using quality load cells that are manufactured by force measurement experts in sensor technologies and experienced in working with vacuum testing labs and experts is an important consideration.

How Do Load Cells Work?

/in

Interface Tech Talk experts answer the question how do load cells work. A load cell’s basic function is to take applied force and convert it into an output signal that provides the user with a measurement. This process of converting a force into data is typically completed through a Wheatstone bridge that is comprised of strain gages. There is a bending beam under the load and when weight or force is applied, the change in bend (deflection) results in change in output.

Why Is Load Cell Zero Balance Important to Accuracy?

/in

Load cell zero balance is the signal of the load cell in the no-load condition. It is defined as the output signal of the load cell with rated excitation and no load applied. It refers to the amount of deviation in output between true zero and an actual load cell with zero load. It is usually expressed in the percentage of rated output (%RO). Zero balance is a test that can be done to understand calibration on a load cell.

What is Static Error Band Output?

/in

Interface Tech Talk answers the question of what is static error band output. SEB is a band encompassing all points on the ascending and descending curves centered on the best-fit straight line. It is expressed in units of %FS. SEB Output at capacity is based on the best fit straight line. Learn how to calculate SEB, the benefits, and an engineering perspective on why SEB output is preferred over terminal output.

What is Moment Compensation?

/in

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.

How Load Cells Can Go Bad

/in

Interface tech talk answers the question, can load cells go bad? Common causes for failure are overloading, mechanical and physical damage to components, environmental exposures and lack of maintenance. Interface force measurement products are engineered for a long life due to quality of design, material construction, build process, calibration, and regular maintenance.
