Technical specifications
General description:
A stationary gas detection system consists of a detector (transmitter) and a central controller. The
detector and the controller are connected with a cable. The detector converts the gas concentration into
an electric measurement signal and transmits it via the cable for processing to the controller.
Gas detectors GS-220.BC.V.ZETA are intended for detection of explosive and toxic gases. They are
suitable for detection of different gases depending on the gas detection element.
Measuring method:
The following measuring methods are used:
1. Catalytic sensors for measurement of explosive gases.
2. Electrochemical sensors for toxic gases.
3. Infrared sensors for CO2.
4. Semiconductor sensors for refrigerant gases.
