About Pressure Gauges

Pressure gauges are used for a variety of industrial and application-specific pressure monitoring applications. Uses include visual monitoring of air and gas pressure for compressors, vacuum equipment, process lines and specialty tank applications such as medical gas cylinders and fire extinguishers. In addition to visual indication, some pressure gauges are configured to provide electrical output of indicated pressure and monitoring of other variables such as temperature.

Products & Services Related to Pressure Gauges

Analog Pressure Gauges

Analog pressure gauges are mechanical devices that include bellows, Bourdon tubes, capsule elements and diaphragm element gauges.

Digital Pressure Gauges

Digital pressure gauges use electronic components to convert applied pressure into usable signals. The gauge readout has a digital numerical display.

Pressure Sensors

Pressure sensors include all sensors, transducers and elements that produce an electrical signal proportional to pressure or changes in pressure.

Pressure Switches

Pressure switches are actuated by a change in the pressure of a liquid or gas. They activate electromechanical or solid-state switches upon reaching a specific pressure level.

Pressure Transmitters

Pressure transmitters translate the low level output of a sensor or transducer to a higher level signal suitable for transmission to a site where it can be further processed. These devices include pressure sensors, transducers, elements, and instruments.

Vacuum Gauges and Instruments

Vacuum gauges are devices for measuring vacuum or sub-atmospheric pressures.
