Load Cell Circuit

The most common types of load cell used are hydraulic pneumatic and strain gauge.

Load cell circuit.

It converts a force such as tension compression pressure or torque into an electrical signal that can be measured and standardized. A load cell is a type of transducer which is a device that converts energy from one form to another. In bar strain gauge load cells the cell is set up in a z formations so that torque is applied to the bar and the four strain gauges on the cell will measure the bending distortion two measuring compression and two tension. You may built your own load cell amplifier to get the lower cost.

Specifically load cells are force transducers converting the kinetic energy of a force such as tension compression pressure or torque into a measurable electrical signal. Except for certain laboratories where precision mechanical balances are still used strain gauge load cells dominate the weighing industry. Here the two scheme diagram of load cell amplifier circuit. The sensitivity of a strain gauge is rated in mv v meaning the maximum output is a function of the excitation voltage.

The strength of the signal changes in proportion to the force applied. Most load cell circuits are setup in a wheatstone bridge configuration which is a simple circuit commonly used to measure an unknown resistance. A load cell is a force transducer. As the force applied to the load cell increases the electrical signal changes proportionally.

A load cell or loadcell is a transducer which converts force into a measurable electrical output.
