equipment class

A pilot switch intended to create a switch action at a pre-set value.

equipment class

A physical object that is intended to rotate within a fluid and to transform energy within a fluid into mechanical power.

equipment class

A velocity flow meter that uses a multi bladed rotor to measure fluid flow rate in units of volumetric flow through a closed conduit.

A transmitter specially designed to convert the signal in a turbine meter into a standardized output signal.

equipment class

A velocity flow meter that measures the velocity of a flow by measuring the time difference between an ultrasonic pulse sent in the flow direction and an ultrasound pulse sent opposite the flow direction.

A flow transmitter providing electrical outputs that are proportional to the flow inputs from an ultrasonic flow meter.

An element intended to determine a level based on ultrasonic sound waves.

A level transmitter that is using ultrasonic sound to continuously monitor the level of a liquid or particulate matter in a tank or vessel.

equipment class

An ac power supply unit that maintains a continuous supply of electric power to the equipment it protects.

equipment class

A differential pressure flow meter that uses a v-cone as the restriction body in the flow stream.

equipment class

A circuit-breaker in which the contacts open and close within a highly evacuated envelope.

An analyser intended to determine a vapor pressure.

equipment class

equipment class

A regulator designed to automatically maintain a constant voltage level.

A signal converter that is intended for converting an input voltage signal into an output current signal.

equipment class

An instrument transformer in which the secondary voltage, in normal conditions of use, is substantially proportional to the primary voltage and differs in phase from it by an angle which is approximately zero for an appropriate direction of the connections.

equipment class

A transmitter which output is relative to a measured voltage.

equipment class

A flow meter that measures the velocity of a fluid in a pipe by detecting the frequency of vortices being shed from a specially shaped obstructing element in the fluid stream.

A transmitter specially designed to convert the signal in a vortex flow meter into a standardized output signal.
