tag class

A functional switch that is intended to give a signal when the flow have reached a pre-set value.

A totalizer that adds up flow measurements.

A flow transmitter providing an output signal that is proportional to the flow inputs from a flow element.

tag class

A device capable of detecting droplets of water vapour suspended in the air near the ground.

An analyser intended to determine the freezing point of a liquid.

A device that generates an electrical signal of a specified frequency.

A signal converter that is intended to convert a frequency or rotational speed input signal into a 0 - 20 mA or 4 - 20 mA current output signal.

tag class

A hollow cone with a tube extending from the smaller end and that is designed to catch and direct a downward flow.

tag class

A physical object that is intended to induce a reaction in a process fluid by heating it.

A chromatograph where gas is injected directly into one or more separation columns.

An analyser which analyses the composition of gaseous mixture with two or more components.

tag class

A detector that is intended to sense the presence of a specified concentration of a gas.

A chromatograph where a liquid sample is injected and evaporated and subsequently carried to one or more separation columns.

A control valve that is a gate valve and an actuated valve.

tag class

tag class

An alarm device that makes a loud warning sound.

A meter intended to measure and indicate and/or produce a signal which represents the measured humidity.

An actuator intended to be operated by hydraulic power.

A controller that is designed or can be programmed to operate and control hydraulic operated systems.

Registers
Registers where this document type is included.
A collection of all instrument set points and/or alarms. Each instrument having an alarm or trip function is listed. Alarms and settings are given as percentages of transmitter range and in engineering units, together with transmitter range, location of the annunciation point, cabinet, identification and relevant P&IDs/PEFS or logic drawing.
An authoritative collection of values with a relationship to instrumentation. The columns of this collection is specified and controlled.
