Values listed under each gas type are in volts.
The log-linear output signal and pressure are related by the following formulas:
P = 10
(V - 5)
V = log
10
(P) + 5
where P is the pressure in Torr, and V is the output signal in volts.
An analog output of less than 0.01 volts to near 0 volt indicates a damaged or faulty sensor.
The chart on the following page shows the graphical results of the table and formulas given above for nitrogen.
True pressure (N
2
) is plotted on the X-axis with a log scale. The output signal is plotted on the Y-axis on a linear
scale.
