tag 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 physical object that detects levels; records, modifies and/or displays or performs a combination of these activities.
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.
A process control unit that can be operated in remote.
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.
