Hydraulic Switches / Transducers

A transducer is an analogue device that usually converts a signal in one form of energy to a signal in another.

Transducers are normally used for high speed control systems and are often employed at the boundaries of automation, measurement and control systems, where electrical signals are converted to and from other physical quantities (energy, force, torque, light, motion, position, etc.). The process of converting one form of energy to another is known as transduction
