Description

SRS develops and manufacture many kinds of Fixed LEL Sensors / gas alarm detectors, based on signal out:  4-20mA, RS485 and RS232; based on the display, have LCD, LED and no display.

Which kind should be choose?  It depends on the gas detected, the working environment and the terminal equipment.

Application Installation Cases

 

Additionally, fixed multi gas detector or LEL Sensors are suitable for the detect concentration of poisonous and harmful, inflammable and explosive gas in the air.  Moreover, It is widely used in metallurgy, Garbage Dump, Leather Factory, power plant and chemical industry.  In addition, it is also used in coal mines, oil mines, on farms, warehouse, tunnels, underground pipeline and other places.  It is effectively reminding and preventing the happening of the accident.

 

Uses in Parking lot: 

 

To detect CO gas concentration in the garage, controller will send an alarm signal quickly when the concentration too high.

 

Applications in the Kitchen: 

 

Furthermore, Home Kitchen, Restaurant Kitchen, Hotel kitchen and many other place use our gas transmitter to detect the natural gas leak precisely.

 

Uses in Tunnel: 

 

Finally, to detect toxic and harmful gases in tunnel, realize real-time data transmission, computer monitoring and alarm quickly.
