Bently Nevada 350800-01-180 Hazardous Gas Sensor
The Hazardous Gas Detection System uses the approved 350800 hazardous gas sensor. This sensor consists of a catalytic bead and a reference bead that form a Wheatstone bridge when connected to the 3500/63 Hazardous Gas Detection Module, as shown in Figure 2-4. The catalytic bead of the sensor (labeled Rreac in Figure 2-4) is impregnated with a catalyst that promotes oxidization, while the reference bead is treated to inhibit oxidization. Electrical current from the monitor heats the beads to a temperature at which gas will oxidize at the catalytic bead. This oxidation, when gas is present, raises the temperature of the catalytic bead above the temperature of the reference bead, which increases its resistance and unbalances the bridge. The imbalance is proportional to the concentration of combustible gas.

The 350810 Remote Haz Gas Calibrator (see Figure 2-1) may only be used in conjunction with the 350800 Hazardous Gas Sensor. If a 350800 Sensor is located in a Zone 1 area, or any area that is difficult to access, the Remote Haz Gas Calibrator will allow calibration of the sensor from a remote location away from the hazardous or confined area.
The 350810 Remote Haz Gas Calibrator is operated pneumatically. There are no electronics associated with the calibrator itself. The line pressure from the calibration gas is used to operate a slide that when closed blocks surrounding air from reaching the 350800 Sensor. The trapped air in front of the sensor is then purged with a metered flow of calibration gas. Turning off the flow of calibration gas allows the slide to return to its original position, which permits surrounding air to reach the sensor and resume online monitoring.
