Simple calibration and setup Poison resistant sensors Ex-proof housings Stationary Monitoring of Combustible Gases and Vapors Protection from combustible gases In areas where combustibles gases are
produced, consumed, or stored, gas / air mixtures can build up unexpectedly to explosive levels. An early warning for combustible gases in ambient conditions is the safest way to avoid life and
property-threatening environments. Fixed gas detection systems allow an early recognition of combustible gases around the clock. A fixed gas monitoring system consists of one or more remote sensors
transmitting to a controller. Detection principle The detection principle for the measurement of combustible gases in the LEL range is the catalytic combustion (CC) sensor. The catalytic combustion
sensor element is heated. When a combustible gas or vapor comes in contact with the sensor the flammable components of the gas are burned on the sensor, changing its electrical resistance. The
change in resistance is proportional to the gas concentration.To ensure stable measurement signals all GfG remote sensors have integrated electronic circuits for voltage stabilization, signal
transmission, and temperature compensation. Remote sensor The remote sensor is the key component of a gas detection system. This is why GfG Instrumentation gives high priority to the development of
gas detection technology and has become a leader in the industry for over 40 years.
