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.
A physical object that is an instrument, machine, machine part, or tool that cuts.
A device that damps, typically a valve or plate (as in the flue of a furnace) for regulating the draft, or a device to stop vibration, typically a shock absorber or snubber.
A physical object intended to carry the load of equipment that is regularly lifted or launched, like a life boat, or of equipment that regularly is removed for inspection or maintenance, such as covers, hatches, etc.
An artefact that is used to control fibrillation of the heart.
A device that removes air or gases (methane, H2S, CO2 and others) from drilling liquids.
A piece of equipment specifically designed to remove moisture from air.
A filtration device used to purify tap water. They are normally composed of various resins that replace positive & negatively charged ions.
A control valve that is intended to operate at high temperature, and admit water into a deluge system.
A physical object intended to catch fluid droplets.
An analysing instrument intended to determine the density of a substance.
A device that provides a safe and rapid method of descent in case of an emergency situation requiring evacuation.
A physical object that is the primary element of a measuring chain which converts the input variable into a signal suitable for measurement.
A physical object that is an assembly of a sensing element and necessary ancillary devices making it able of detecting a state, e.g. pressure, temperature, or detect the presence of a selected substance, and produce a signal based on the detection.
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 pressure tank divided into two areas: the upper is a fluid storage area and the lower is a gas pressure area with the two areas separated by a diaphragm.
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.
