CGS500 Combustible Gas Sensor: The CGS500 combustible gas sensor is designed to measure the concentration of combustible gases within the range of 0-100 MLEL. CGS500 is installed in an EExe certified junction box. Each sensor contains two thermal catalytic beads. Combustible gases will oxidize on the surface of active beads, while reference beads will compensate for changes in temperature, pressure, etc. Each bead is composed of a circle of fine platinum wire, surrounded by an alumina based substrate containing a catalyst.

Electric current passes through the beads, raising the temperature to a level where oxidation occurs. The catalyst reduces the temperature at which oxidation occurs, thereby extending the lifespan of the beads and greatly reducing power consumption.

T100 transmitter: T100 is a 4-20mA two-wire transmitter that can measure various gases and is installed in a sturdy and compact metal casing. It combines advanced SMD electronic devices with a 3-electrode electrochemical sensor based on micro fuel cell technology, designed to be maintenance free and inherently stable. The sensor utilizes highly successful hand tube diffusion barrier technology, resulting in a low temperature coefficient, direct response to concentration, and relatively unaffected by pressure. The use of electrodes based on dry fuel cell technology can provide highly active materials, thereby achieving long-term stability.

The gas diffused to the sensor electrode reacts on the electrode surface through oxidation (such as CO, H2S, SO2, NO, H2, HCN, HC1, C2H40, NH3) or reduction (NO2, 03, and CI2). The reaction is catalyzed by specially developed electrode materials and designed to be specific to the gas being sensed
