They are a kind of device of indicating output value of load, displacement
acceleration, pressure, torque coming from sensor used strain gage.

They are used a lot as displacement measure or controlling sensor &
Transducer changing load or physical change to linear displacement

They are used a lot as displacement measure or controlling sensor &
Transducer changing load or physical change to linear displacement

They are being measured or controlled by torque, angle and speed of motor and applied industrial department such as produce, process, quality, test, certification and inspect.

They are a kind of sensors of measuring pressure power ( tension, compression.
