equipment class
A detecting instrument that is intended to analyse a substance for its composition and/or properties.
A switch intended to switch or give an on/off signal when the measured variable has reached a pre-set value.
A regulator that operates automatically to affect a controlled variable by comparing the value of the controlled variable with the value of a reference variable in order to reduce the difference between them.
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.
A detecting instrument intended to measure and indicate flow rate and/or produce a signal which represents the measured flow rate.
A totalizer that adds up flow measurements.
A detecting instrument that is used for measuring or testing.
A process instrument that records values represented by the input signal(s).
A device which gives a visual indication of a measured value.
A device that is capable of three-phase metering of liquid, oil and gas.
A physical object that is a thin plate with a specified hole in the middle. It is usually placed in a pipe to measure the rate of fluid flow.
An electric signal transducer that is intended to convert one type of standardized transmission signal into another.
An instrument panel dedicated to a particular system.
A physical object that detects temperatures; records, modifies and/or displays or performs a combination of these activities.
A physical object that is an element that receives a process variable signal from a sensor and converts it into an output signal.
