Piezoelectric load cells work on the same principle of deformation as the strain gauge load cells, but a voltage output is generated by the basic piezoelectric material – proportional to the deformation of load cell. Useful for dynamic/frequent measurements of force.
An unmounted resistive foil strain gauge. A strain gauge takes advantage of the physical property of electrical conductance and its dependence on the conductor's geometry. . When an electrical conductor is stretched within the limits of its elasticity such that it does not break or permanently deform, it will become narrower and longer, which increases its electrical resistance end-to-

A torque transducer, similar to a load cell, is an electronic device used to convert torque into an electrical signal. This conversion is indirect and happens in two stages. Through a mechanical arrangement, the torque being sensed deforms a strain gauge. The strain gauge converts the deformation to electrical signals
Strain gauges can be used to experimentally determine the deformation of a physical part. A commonly used type of strain gauge is a thin flat resistor that is affixed to the surface of a part, and which measures the strain in a given direction. From the measurement of strain on a surface in three directions the stress state that developed in ...
The simplest force platform is a plate with a single pedestal, instrumented as a load cell. Better designs have a pair of rectangular plates, although triangular can also work, one over another with load cells or triaxial force transducers between them at the corners.
The change in material stress deforms the sensor, in which strain gauges are mounted as in a classic load cell. Thus, the weight of the individual wheelset or bogie can be calculated from the specific deformation behaviour of the rail. Advantages: Can be used as a wheel load scale and axle load scale,
