It is important to measure the heater voltage as close to the sensor as possible due to voltage drops in the supply cable. The heater can also be operated with an equivalent AC or PWM signal. 2. The constant current source used in the pump circuit should be designed to drive a load of up to 6 kΩ. 3. For gas temperatures above 200 °C the heater supply voltage has to be decreased accordingly.
