The probe measures the residual oxygen content in a measuring chamber at the end of the measuring gas fitting. The probe signal can be tapped off as a voltage. The probe is heated with a constant voltage. For supplynig the heating only power supply inits approved by MESA may be used. The quantily of gas passing the probe should be within a range of 20...50 l/h. Too much gas volume can change the highly constant probe temperature, which results in a falsification of the measured value. Every probe includes two contants ( K1 and K2 ). These constants must be entered in the measuring instruments ( e. g. intelligent measuring transmitter MP 47, Carbomat-M ). If not there will be some measuring faults.
