fixed industrial flammable gas detector KB-501

Industrial gas detector fixed flammable gas detector Intrinsically safety circuit design ISO9001:2000 certificate

Industrial gas detector

 

KB-501 is a new type combustible gas detector which used high performance catalytic combustion gas sensor and sophisticated SMD technology. It has following advantages: good repeatability,high resistance to humidity-temperature jamming, long performance life and simple operation. It is applied to inspection for gas concentration in industrial environments.

 

KB-501 can translate the combustible gas concentration signals into electric current signals or digital signals for outputting and transmitting. It adopted three-wire (4~20mA signals output) and four-wire (RS485 bus output) system, remotely examine the detection result through the monitor or controller. Common applications is gas safety inspection and alert for industrial scene, such as petroleum refinery, chemical plants, LPG stations, boiler rooms, gas stations, paint spray booths, etc.

Features

• Advanced catalytic combustion sensor;

• Intrinsically safety circuit design;

• Three-wire system 4~20mA standard signals output and long distance transmission;

• RS485 bus output (optional);

• Possible to connect to DCS system directly;

• The probe has following advantages: high sensitivity, quick-response capacity, long performance life and short polarization time.
