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

Air pressure regulators control pressure in air lines (usually adjustable) to remove fluctuations and maintain consistent pressure for pneumatic devices

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

Liquid level switches are used to detect specific liquid levels or interfaces between liquids. These level measurements are indicated via an electrical switching action

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

Gas flow switches and liquid flow switches, velocity, are used to measure the flow or quantity of a moving fluid in terms of velocity, such as feet per minute

Pressure controllers accept input from pressure sensors, transmitters, gauges, and other devices and subsequently control adjustment to the pressure to maintain or achieve the desired pressure level

Pneumatic relays and volume boosters control output air flow and pressure in response to a pneumatic input signal. They can perform simple functions such as boosting or scaling the output, or use complex reversal, biasing, and math function operators

Emergency stop switches are devices that users manipulate to initiate the complete shutdown of a machine, system, or process

Mechanical safety interlock switches couple a moveable guard door with the power source of the hazard. When the guard door is opened, the power is isolated, ensuring that the machine does not pose a hazard while an operator requires access
