1.3.7 Sensor
The Neutronics ZR100 rapid-response zirconium oxide sensor is a solid-state ceramic device. When
heated in its unique oven, it produces a predictable electrical output in response to changes in the partial
pressure of oxygen of a sampled gas, ranging from 0.1 PPM to percent concentration of oxygen. The
most notable advantage of the ceramic sensor technology is its ability to rapidly measure oxygen through
large step changes in concentration. The ZR100 sensor can accurately measure PPM concentrations of
oxygen within seconds after exposure to air.
1.3.8 Remote sensor module (RSM)
The separate remote sensor module (RSM) houses the sensor, the heater assembly, and the delivery
system for the gas sample. Gas is directed in a continuous flow through the sampling system to the
oxygen sensor. The sensor determines the oxygen concentration of the gas in real time. The RSM is an
integral part of the Model 3100 analyzer system (see Figure 6). It is available in two (2) configurations:
pump-driven and positive pressure-driven. Refer to the Remote Sensor Module instruction manual for
more details.
