Pressure Gauges

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…

Pressure Switches

Pressure Switches

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…

Pressure Transducers

Pressure Transducers

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…

Air Pressure Switches

Air Pressure Switches

A mechanical device called an air pressure switch uses pressure to regulate how an electric air compressor operates. The device’s air pressure circuit mechanism supplies the motor with electricity. A pressure switch relief valve is a…

Differential Pressure Switch

Differential Pressure Switch

Differential pressure is the difference in pressure between two points that is measured using different types of pressure sensing devices. An essential part of differential pressure measurement are gauges and switches that are…

Level Switches

Level Switches

A level switch is an electrical or mechanical method for measuring the level of a liquid, powder, or granule material. It is designed to activate an alarm if the material level in a container passes a predetermined height or depth…
