The sensitivity of a strain gauge is rated in mv v meaning the maximum output is a function of the excitation voltage.
Load cell circuit.
The most common types of load cell used are hydraulic pneumatic and strain gauge.
Although there are many varieties of force sensors strain gauge load cells are the most commonly used type.
It converts a force such as tension compression pressure or torque into an electrical signal that can be measured and standardized.
The strength of the signal changes in proportion to the force applied.
As the force applied to the load cell increases the electrical signal changes proportionally.
A load cell is a type of transducer which is a device that converts energy from one form to another.
Most load cell circuits are setup in a wheatstone bridge configuration which is a simple circuit commonly used to measure an unknown resistance.
You may built your own load cell amplifier to get the lower cost.
Except for certain laboratories where precision mechanical balances are still used strain gauge load cells dominate the weighing industry.
A load cell is a force transducer.
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.
A load cell or loadcell is a transducer which converts force into a measurable electrical output.
Here the two scheme diagram of load cell amplifier circuit.
