About Analog Pressure Gauges

There are several common types of mechanical analog pressure gauges including bellows, Bourdon tubes, capsule elements and diaphragm element gauges. Analog pressure gauges should be selected considering the media and ambient operating conditions. Gauge selection should take into consideration the corrosive environment in which it is to operate. The media being measured must be compatible with the wetted parts of the pressure instrument. Improper application can damage the analog pressure gauge, causing failure or personal injury and property damage. Diaphragm seals (also called gauge isolators) can be added to the system to protect the gauge from corrosive attack, and prevent viscous or dirty media from clogging Bourdon tube analog pressure gauges.

Products & Services Related to Analog Pressure 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 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.

Pressure Instruments

Pressure instruments are used to measure, monitor, record, transmit or control pressure.

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 Sensors

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