An analysing instrument intended to determine the dew point of a substance.

A facility for measuring dew point and transmitting a signal representing the measured temperature.

A diaphragm 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.

A seal between two substance created of a impenetrable membrane.

A membrane valve that is a membrane valve where the closure member is a resilient diaphragm being forced against a port.

An internal combustion engine in which ignition of the fuel injected into the cylinder is performed by the heat of compression of the air charge.

Is an artefact that automatically maintains a constant difference in pressure between two points in a fluid handling system by regulating flow.

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

A gauge that is intended for measuring and indicating pressure differences.

A level transmitter that is measuring liquid level by sensing pressure difference between two points, e.g. the hydrostatic pressure at the bottom of a tank to the atmosphere pressure.

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

A pressure transmitter that is producing a standardized output signal dependent of a received pressure difference signal.

A physical object that contains a diverging channel-shaped chamber in which part of the kinetic energy of the fluid is converted into pressure energy.

An electric generator for the production of direct current and voltage.

An electric motor for operation by direct current.

A direct digital controller is an electronic device that uses a microprocessor for closed loop control of a process by reading inputs from sensors, computing the required outputs, and signaling the actuators accordingly without converting signals to analog.

Is a specialised fitting inserted between pipe sections that enables quick, repeated assembly and disassembly of the pipe connection without damage for adjustment, inspection, cleaning, replacement or transportation purposes.

A level transmitter which uses a displacer as sensing element.

An analyser intended to determine the relation between the boiling temperatures and the fraction distilled. It includes the initial boiling point and the final boiling point.

A switchgear and controlgear that is an insulated panel carrying terminals, fuses, etc, for controlling a number of subsidiary electrical circuits.

Is a large-scale centralized facility that chills water or produces cooled fluids.

Is a system that chills water or produces cooled fluids.
