A device compensating for axial or radial movement between two elements that is connected.

A physical object that is driven by a prime mover by which energy is either constantly or periodically added to an amount of gas in order to increase its pressure.

A physical object that can store data and program(s) that operates on the data. A general purpose computer can be programmed to solve any reasonable problem expressed in logical and arithmetical terms.

A transmitter measuring how much of a given substance there is mixed with another substance and transmit a signal proportional to the measured level.

A cooler that is intended to change a vapour to liquid.

A detecting element or probe that is used with a conductivity meter to measure the conductivity of a liquid.

A transmitter that is producing a standardized output signal dependent of a received input signal from a conductivity meter.

A transmitter that is intended to measure and transmit conductivity.

A mechanical switching device having only one position of rest, operated otherwise than by hand, capable of making, carrying and breaking currents under normal circuit conditions including operating overload conditions.

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 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.

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

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.

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 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.

An instrument transformer in which the secondary current, in normal conditions of use, is substantially proportional to the primary current and differs in phase from it by an angle which is approximately zero for an appropriate direction of the connections.

A transmitter that transmits an analogue electrical current.
