A pressure transmitter where pressure is applied to one side of the sensor while the other side has a vacuum chamber.
A physical object for storing energy, and which after discharge may be recharged.
A physical object for changing a signal into a corresponding movement.
A physical object that supplies and mixes air to a liquid or solids.
A propeller like device with agitational or rotational movement located in a tank to prevent the content of the tank to build component segments.
An air balancing unit on a nodding donkey.
A circuit-breaker in which the contacts open and close in air at atmospheric pressure.
An artefact intended for central conditioning and pressure increase of ventilation air.
A physical object that is intended to process and annunciate alarms.
An electric motor driven by alternating electric current.
Is an artefact intended to retrieve a material at a particular location and inserted into something so as to test its conditions.
A detecting instrument for recording wind speed, and possibly wind direction.
An automatic gas feeder is a device used to control and monitor the regulated flow rate of a gas to a process by automatically adjusting its output in response to measurements from flow transmitters and inline gas analyzers.
A dynamic compressor in which the gas is accelerated by the action of a bladed rotor and where the main flow is along the rotation axis of the rotor.
A detecting element that is intended to detect axial displacement.
A transmitter measuring an axial displacement and generating a standardized output signal representing the axial measured displacement.
A Building Automation and Control Network controller
Biochemical oxygen demand (also known as BOD or biological oxygen demand) is an analytical parameter representing the amount of dissolved oxygen (DO).
A physical object intended to compress and supply air or gas at medium pressure and medium volume flow.
An indirect contact heat exchanger that is intended to heat a liquid.
A respirator in which air or oxygen is fed to a face mask carried by the wearer via a demand valve.
Is a support structure intended to span a space.
A corrosion protection system using sacrificial anodes or impressed current anodes offering material and giving protection to carbon and low-alloy steel equipment or structures.
A butterfly 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.
A protective device used to protect equipment (e.g. riser pipes and submerged pumps) against environmental exposure.
