How It Works
This product is a strain gauge, specifically a shear beam load cell type. A strain gauge is a sensor that measures strain. When a force is applied to a material, it causes deformation, known as strain. This strain causes a change in the electrical resistance of the strain gauge. This particular strain gauge is made from alloy steel and has a capacity ranging from 0.5 to 10 tonnes. Its design as a shear beam allows it to accurately detect these changes in resistance as a result of applied load.
Measuring the Output
The output of this strain gauge is measured in millivolts per volt, with a rated output of 2.0 mV/V. This value indicates the change in voltage output for a given change in applied force, relative to the excitation voltage. The strain gauge operates with an input resistance of 350 Ω. This electrical signal directly corresponds to the amount of strain experienced by the alloy steel beam. The C3 accuracy class ensures reliable and consistent readings for the measured strain.
Common Applications
This strain gauge is designed for compatibility with platform and hopper scales. Its capacity of 0.5 to 10 tonnes makes it suitable for a range of weighing applications where moderate to heavy loads are measured. The shear beam load cell type is commonly used in industrial settings for precise weight measurement. The alloy steel construction provides the necessary durability for demanding environments found in these applications.
How They Work
Strain gauges, including this beam strain gauge, function by converting mechanical strain into an electrical signal. When a load is applied to the alloy steel beam, it deforms slightly. This deformation stretches or compresses the resistive wire within the gauge, altering its electrical resistance. This change in resistance is then measured. The specific design of this shear beam load cell allows it to accurately detect these changes, providing a reliable measurement of the applied force.
Measuring the Signal
The signal from this strain gauge is a change in electrical resistance, which is then converted into a voltage output of 2.0 mV/V. This output is typically fed into an amplifier and then to a display or control system. The input resistance of 350 Ω is a key electrical characteristic for integrating the sensor into a measurement circuit. The C3 accuracy class indicates the precision with which the strain gauge measures and outputs this signal, ensuring reliable data for platform and hopper scale systems.
