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

An electric converter for converting an alternating current into a direct current.

A recuperator is a special purpose counter-flow energy recovery heat exchanger positioned within the supply and exhaust air streams of an air handling system, or in the exhaust gases of an industrial process, in order to recover the waste heat.

An analyser intended to determine the oxidation and reduction capability of material.

A pressure transmitter where pressure is applied to one side of the sensor while the other side is open to atmosphere. The transmitter generate standardized output signal representing the measured value.

A physical object that can be any electrical device, usually incorporating an electromagnet, whereby a current or signal in one circuit can open or close another circuit.

A self operating valve that is set to open at a certain pressure level to prevent the pressure in a container or system from reaching unsafe levels.

A RTU, or Remote Terminal Unit is a device which interfaces objects in the physical world to a DCS or SCADA system by transmitting telemetry data to the system and/or altering the state of connected objects based on control messages received from the system.
