A pipe or tube that has a constriction with a relative long passage with a smooth coned entry and exit.

A detecting element that is intended to sense mechanical vibration and in which the oscillating motion is transferred into a voltage or current signal.

A switch intended to give a on/off signal when vibration level have reached a pre-set value.

A transmitter of which the output is proportional to a measured vibration.

A facility with the capability of receiving video signals and displaying pictures.

A recording instrument that is recording signals originated by a TV camera on a moving magnetic tape for subsequent reproduction or transmission.

An analysing instrument intended to determine the viscosity of a fluid.

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

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.

A transmitter which output is relative to a measured voltage.

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

A transmitter for weighing large quantities of material, and of which the output is proportional to the measured weight.

A power transformer of which the magnetic circuit and windings are immersed in oil.

A powerful machine with one or more drums on which to coil a rope, cable, or chain for hauling or hoisting.

A detecting element that can be the sensing element of an anemometer or wind gauge.

A hoist utilizing a wire-rope for suspending load. Wire hoists are normally electrically powered, but also (hand) lever types exists.

A wireless access point (WAP) is a device that allows wired communication devices to connect to a wireless network using Wi-Fi, Bluetooth or related standards. The WAP usually connects to a router, and can relay data between the wireless devices (such as computers or printers) and wired devices on the network.

An analysing instrument intended to determine the wobble index of a gas.
