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

Pressure sensor chips are micro-machined semiconductor devices that sense changes in pressure

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

Pressure regulators are used to maintain a constant outlet pressure or flow

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

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

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

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

Level sensors are used to detect liquid or powder levels, or interfaces between liquids. There are two basic level-measurement types: continuous and point or multi-point

Pressure relief valves are self-actuated safety valves designed to relieve excess pressure upstream from the line

Oil sensors and oil analyzers are used in automotive or industrial machinery applications to sense oil levels, and check for contamination, and particulates, viscosity and/or temperature

Pressure intensifiers are pressure-increasing devices used to raise the pressure of hydraulic or pneumatic fluids. They differ from pumps in that they can only increase the pressure of a normally pressurized fluid

Flow meters (flowmeters) and flow sensors are devices used for measuring the flow rate or quantity of a moving fluid or gas

Liquid level sensors are used to detect liquid levels or interfaces between liquids such as oil and water or liquids and solids.
