A terminal box that is used as accommodation for control function circuits.

A module for control functions.

An instrument panel containing a set of indicating devices and control units required for operation of a system or part of it.

A switch intended to switch or give an on/off signal when the measured variable has reached a pre-set value.

A valve that can be used to modify (regulate) the fluid flow rate in a process control system. It usually includes an actuator, which responds to a signal from the controlling system and changes the position of the flow controlling element in the valve.

A regulator that operates automatically to affect a controlled variable by comparing the value of the controlled variable with the value of a reference variable in order to reduce the difference between them.

A pressure relief valve that has its closing force provided by a spring.

A physical object for moving articles or bulk material from place to place (as by an endless moving belt or a chain of receptacles).

A heat exchanger that is intended to cool a physical object.

A pipe coil in which heat is transferred from the material or space cooled to the primary refrigerant.

A cooler and an air cooled heat exchanger that is a tall structure through which air circulates by convection.

An element located in a flowstream using the Coriolis principle to measure the flow.

A mass flow meter that uses the Coriolis principle to measure a mass flow rate through the meter.

A gallery or passage connecting parts of a building.

A detecting element that is a piece of suitable metal meant to corrode and give an indication of the corrosion rate.

A detecting instrument intended to measure, indicate and/or produce a signal which represents the rate or degree of corrosion.

A transmitter that is producing a standardized output signal dependent of a received input signal from a corrosion sensor.

A detecting instrument that counts, especially an electronic or mechanical device that automatically counts occurrences or repetitions of phenomena or events.

Connecting with a coupling or coupler.

A lifting appliance that is a tower or derrick equipped with cables and pulleys that can lift or lower and move loads in multiple directions.

A block with a hook for use with a crane.

A mill that uses pressure or impact to reduce the particle size of solid materials.

A signal converter that is intended to convert one current signal to another current signal.

A signal converter that is intended to convert an analogue signal (4 - 20 mA) to a proportional linear pneumatic output signal.

A signal converter that is intended to convert a current input signal to a proportional voltage output signal.
