SENSOR CHARACTERISTIC CURVES
4.
Sensor characteristic curves
The characteristic curve of the 12K NTC-Sensor Duplex screw-in sensor, which is used as the boiler sen sor, is iden-
tical to the characteristic curve of the flue gas sensor, called the 12K NTC- Sensor screw-in sen sor.
The characteristic curve of the pressure sensor module MCTH-1 (0....10 bar) is linear. The signal voltage of the sen-
sor at 0 bar is always 0.5V and at 10 bar is always 4.5V.
