A pressure gauge is a method of measuring fluid, gas, water, or steam intensity in a pressure powered machine to ensure there are no leaks or pressure changes that would affect the performance of the system. Pressure systems are designed to operate within a specific pressure range...
A pressure switch is a mechanical or electronic device activated by the pressure of the process fluid upon reaching a certain threshold or setpoint. A pressure switch can have a bourdon tube, piston, diaphragm, or membrane that moves or deforms according to the amount of pressure exerted by the system...
A pressure transducer is a mechanical device that converts applied pressure, a physical quantity, into a measurable and industry-standard electrical signal which is linearly and proportionally related to the applied pressure...
