A physical object that comprises a printed circuit board with electronic components intended for receive, process/transform and transmit electrical signals.
A controller that uses in-built algorithms executed by electronic circuitry to perform its function.
Is a network security device, either hardware- or software-based, that monitors and controls incoming and outgoing network traffic based on a set of security rules in order to protect internal private networks from unauthorized access, malicious attacks, or intrusions.
A detector that is intended to sense a flame.
A specially designed switch with connections for inputs from multiple flame detectors. The switch has a built in logic to determine the presence of a flame based on these inputs.
An analysing instrument intended to determine the flash point of a substance.
A detecting element that is producing a signal that is proportional to a flow rate.
A gauge intended to indicate a liquid or gas flow.
A regulator that normally use the differential pressure principle across an orifice to control the valve trim and regulate flow.
A functional switch that is intended to give a signal when the flow have reached a pre-set value.
A totalizer that adds up flow measurements.
A flow transmitter providing an output signal that is proportional to the flow inputs from a flow element.
A device capable of detecting droplets of water vapour suspended in the air near the ground.
An analyser intended to determine the freezing point of a liquid.
A device that generates an electrical signal of a specified frequency.
A signal converter that is intended to convert a frequency or rotational speed input signal into a 0 - 20 mA or 4 - 20 mA current output signal.
A chromatograph where gas is injected directly into one or more separation columns.
An analyser which analyses the composition of gaseous mixture with two or more components.
A detector that is intended to sense the presence of a specified concentration of a gas.
A chromatograph where a liquid sample is injected and evaporated and subsequently carried to one or more separation columns.
A detecting instrument that is used for measuring or testing.
A process instrument that records values represented by the input signal(s).
A personal H2S monitor is a device that detects the presence of hydrogen sulphide.
A detector capable of detecting both heat and smoke.
An alarm device that makes a loud warning sound.
