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.
