An authoritative collection of values with a relationship to instrumentation. The columns of this collection is specified and controlled.
A pressure transmitter where pressure is applied to one side of the sensor while the other side has a vacuum chamber.
An enclosure that totally or partially surrounds an item in order to reduce its emitted noise.
A physical object that is intended to process and annunciate alarms.
Is an artefact intended to retrieve a material at a particular location and inserted into something so as to test its conditions.
A detecting instrument for recording wind speed, and possibly wind direction.
An electromagnetic transducer that is a physical object made of conducting material which is capable of radiating or receiving electromagnetic waves.
An attenuator is a telecommunication device that reduces the amplitude of a signal without appreciably distorting its waveform. Attenuators are usually passive devices. The degree of attenuation may be fixed, continuously adjustable, or incrementally adjustable.
An automatic tracking system used on ships and by vessel traffic services (VTS) for identifying and locating vessels.
A detecting element that is intended to detect axial displacement.
A transmitter measuring an axial displacement and generating a standardized output signal representing the axial measured displacement.
A ball 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 valve that can be used for rapid depressurizing of a high pressure system.
A butterfly 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.
Intended to measure quantities of absorbed or evolved heat or to determine specific heats.
A level transmitter which uses the capacitance of the process material.
A detecting element that is intended to detect changes in the dielectric constant.
Closed-Circuit TeleVision Camera capable of acquiring and delivering to a recording device full-motion video.
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.
A timepiece for the measurement of time.
An analysing instrument that is intended to determine the cloud point of a fluid.
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.
An instrument that indicates either a) magnetic bearings by alignment of its needle on the magnetic poles, or b) reference bearing by radio signal, or c) change of orientation in relation to a gyromaintained line.
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 detecting element or probe that is used with a conductivity meter to measure the conductivity of a liquid.
