For nitrogen at a pressure of 760 Torr and a temperature of 20°C the mean free path (l) is less than 1 x 10-7 meters and is inversely proportional to pressure. Since the thermal transfer distance (Dx) is a few micrometers, this sensor will remain in the molecular flow regime at a much higher pressure (10 Torr) than is typical for a thermal vacuum gauge. This extends the linear response part of the output curve up into the 1 Torr range. The nonlinear transition region will extend up to 1000 Torr.

5.3.Dual Sensor Operation

The microprocessor in the control unit continuously monitors the outputs of both the piezoresistive sensor and the Pirani sensor. Figure 5.4 shows representations of the sensors output over the pressure range from 10-5 Torr to 10+3 Torr. The microprocessor uses the output of the piezoresistive sensor at high pressures (>32 Torr) and uses the output of the Pirani sensor at low pressures (<8 Torr). In the crossover region, a software averaging algorithm ensures a smooth transition between the two sensors.
