An authoritative collection of values with a relationship to instrumentation. The columns of this collection is specified and controlled.
A radio transmitter, usually non-directional, that emits identifiable signals intended for radio direction-finding.
A transceiver which has the methods of signalling through space, without connecting wires.
A level transmitter that is producing a standardized electrical output signal based on the input signal from radioactive level measurements.
Intended to generate radioactive radiation.
Is a piece of hardware intended to read and decode information encoded on a carrier.
A process instrument that records values represented by the input signal(s).
An analyser intended to determine the oxidation and reduction capability of material.
A pressure transmitter where pressure is applied to one side of the sensor while the other side is open to atmosphere. The transmitter generate standardized output signal representing the measured value.
A temperature sensing element that operate on the principle of changes in electrical resistance of pure metals (sintered semiconductor material) and are characterized by an almost linear positive change in resistance with temperature.
An orifice plate that is intended for use as a restrictor.
A variable area flow meter which consists of a tapered tube of glass with a float inside that is pushed up by flow and pulled down by gravity.
A detecting element that is intended to sense rotational speed.
A router is a computer networking device that forwards data packets toward their destinations through a process known as routing. Routing occurs at layer 3 (Network layer) of the OSI seven-layer model.
A physical object that is a pressure relieving device designed to burst at a calibrated pressure to prevent pressure in systems or vessels from reaching unsafe levels.
A sample loop adds a predetermined volume to the process.
A physical object intended to be used to collect and contain representative specimens or selections.
A detector intended to detect sand in a fluid.
A system that provides voice and telefax communication via satellites.
A manual control switch which has more then two possible positioning states.
A tank gauge that is intended to intermittently lower a displacer to measure a liquid level, bottom level, interface level or density.
A detectable transmitted energy (e.g. voltage, current, pneumatic or magnetic field strength) by which information can be transmitted.
A physical object that is capable of receiving a signal and where the signal can be stored, recorded or converted into a useful form.
A device with one input and at least two outputs used for dividing a detectable transmitted energy (as a voltage, current, or magnetic field strength) by which information can be transmitted.
An acoustic device producing a loud sound as a signal or warning.
A slide 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.
