MEASURING POINTS OF BKS AND OXS
17 - 6
ETC00781(1) Series 100 e 10/2001
Rosemount Analytical
Fig. 17-2: PCB “OXS”, assembled, horizontal projection
17.2 Measuring points of OXS (electrochemical oxygen measurement)
17.2.1 Sensor Signal
Measuring device: DVM
Measuring point: Tp 1 (Signal)
Tp 2 (
⊥⊥
⊥⊥
⊥)
Signal: At ambient air (approx. 21 Vol. - % O
2
): 700 mV to 1000 mV
Failure: No signal or faulty voltage
Possible reasons: a) Oxygen sensor not connected to PCB "OXS"
b) PCB “OXS” not connected / faulty
c) Oxygen sensor faulty or consumed
d) BKS faulty
Note !
If the measuring value is lower than < 700 mV at gas flow with ambient air, the sensor is consumed.
Exchange the sensor.
