An authoritative collection of values with a relationship to instrumentation. The columns of this collection is specified and controlled.
A device used to translate print media into computer language so that a document can be viewed and read later on.
A valve that is intended for subsurface control/check operation.
A 'detector' for measuring the velocity, mass, charge, flight direction, and number of dust particles in space.
A detector intended to detect a leakage current to earth.
A control valve that uses a rotating disc as closing element, and with a design that causes the disc to take a slightly eccentric path during actuation.
An actuator that produces a specified movement when excited by an electric signal.
An element located in a flowstream measuring the flow using electro-magnetic forces.
A flow transmitter that is specially designed to convert the signals from an electromagnetic flow meter into a standardized electrical output signal.
A controller that uses in-built algorithms executed by electronic circuitry to perform its function.
A radio beacon in the mobile service the emissions of which are intended to facilitate search and rescue operations (EPIRB).
A valve that is assigned to act in case of emergency.
Machine capable of transmitting written input via telephone lines.
A detector that is intended to sense a flame.
A specially designed switch with connections for inputs from multiple flame detectors. The switch has a built in logic to determine the presence of a flame based on these inputs.
An analysing instrument intended to determine the flash point of a substance.
A computer that is specially designed and programme to calculate flow and to correct for external influence.
A gauge intended to indicate a liquid or gas flow.
An orifice plate which restrict the flow and thus develops the differential pressure that is proportional to the square of the flow rate.
A regulator that normally use the differential pressure principle across an orifice to control the valve trim and regulate flow.
A functional switch that is intended to give a signal when the flow have reached a pre-set value.
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.
A chromatograph where gas is injected directly into one or more separation columns.
