4 Combustible Gas Analyzer Section

The combustibles analyzer (see Figure 4) is a compact detector for reliably sensing all combustible gases. The analyzer consists of two parts:

(1)The control unit housing the calibration controls, analyzer circuitry, meter readout, alarm relays and power supply.

2)The sensor unit including the sensor, flowmeters, valves and heater circuit. (Heater power is controlled through the same RANGE switch that controls oxygen analyzer power (see Dwg. B-l0913).
