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 changing a signal into a corresponding movement.
A physical object that is intended to process and annunciate alarms.
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 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 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.
Intended to measure quantities of absorbed or evolved heat or to determine specific heats.
A level transmitter which uses the capacitance of the process material.
A detecting element that is intended to detect changes in the dielectric constant.
A valve that permits fluid to flow in one direction only.
A chemtroller is a device used to regulate and monitor chemical processes.
A choke 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.
An analysing instrument that is intended to determine the cloud point of a fluid.
The temperature at which either the fuel specimen ceases to flow through a filter within 60 seconds or fails to return into the test jar is recorded as the Cold Filter Plugging Point.
A transmitter measuring how much of a given substance there is mixed with another substance and transmit a signal proportional to the measured level.
A detecting element or probe that is used with a conductivity meter to measure the conductivity of a liquid.
A transmitter that is producing a standardized output signal dependent of a received input signal from a conductivity meter.
A transmitter that is intended to measure and transmit conductivity.
A valve that can be used to modify (regulate) the fluid flow rate in a process control system. It usually includes an actuator, which responds to a signal from the controlling system and changes the position of the flow controlling element in the valve.
