A detecting element intended to sense pressure.

A gauge intended to measure and display a representation of a measured pressure.

A regulator that is controlling/regulating the pressure in a system.

A gas flow damper that is used to relieve built-up pressure in a duct system to prevent damage to HVAC equipment.

A functional switch that (usually) turns an electrical circuit on or off when the pressure level reaches a pre-set value.

A signal converter that is intended to convert a pressure input signal to DC output signal.

A transmitter that is producing a standardized output signal dependent of a received input signal from a pressure element.

Is a facility for measure & control, including the main plant computerized operational system, where all process, utility and off site activities are monitored. The system may be located in the main control room. (e.g. PLC Programmable logic controller, DCS distributed control system, ENMC Electrical Network Monitoring and Control system).

A measuring relay that, either solely or in combination with other relays, is a constituent of a protection equipment.

A detecting element that is intended to sense proximity.

A position switch that is operated without mechanical contact with the moving part.

Is an alarm system.

A physical object that adds or removes mechanical energy to a fluid, either constantly or periodically.

A manual control switch that is intended to switch when you push or touch the button.

A physical object for detecting the presence of objects at a distance, or ascertaining their position or motion, by transmitting short radio waves and detecting or measuring their return after being reflected.

An element intended to determine a level based on high frequency electromagnetic waves.

A level transmitter that is producing a standardized electrical output signal based on the input signal from a radar type level sensor.

A radio transmitter, usually non-directional, that emits identifiable signals intended for radio direction-finding.

A transceiver which has the methods of signalling through space, without connecting wires.

A level transmitter that is producing a standardized electrical output signal based on the input signal from radioactive level measurements.

Intended to generate radioactive radiation.

Is a piece of hardware intended to read and decode information encoded on a carrier.

A positive displacement compressor in which forced reduction of gas volume takes place by the movement of a displacing element in a cylinder or enclosure.

A positive displacement pump which contains a displacing element intended to be moved in a reciprocating movement to exert pressure on a fluid, typically moving within a cylindrical space.

A process instrument that records values represented by the input signal(s).
