Equipment
Equipment that requires this document type.
tag class

Is a shaft (civil) intended to transport flue gas to a high location in the atmosphere. It may also be used to supply fresh air via a separate flue.

A choke valve that is equipped with an actuator that manipulates a stream of fluid in the response to a signal from an external sensing element and with input of energy from an external source.

An analysing instrument that is intended to determine the cloud point of a fluid.

tag class

A transmission that is intended to transmit energy between two shafts providing the capability to connect and disconnect the shafts.

tag class

A gravity separator where two liquid substances separates and where the substance with the less gravity can be skimmed off.

The temperature at which either the fuel specimen ceases to flow through a filter within 60 seconds or fails to return into the test jar is recorded as the Cold Filter Plugging Point.

tag class

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

tag class

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.

tag class

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.

tag class

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.

tag class

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

tag class

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 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.

tag class

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

tag class

Connecting with a coupling or coupler.

tag class

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.

tag class

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