Q: I have TAI Oxygen analyzer models 353 and 354 that call for a B5 micro-fuel cell. I also have continuous operation tunnel sensors that need a B3 fuel cell. Are the B5 and B3 sensors interchangeable with the 354 Oxygen Monitor?
A: The class B3 sensor is not interchangeable with the B5 sensor. The output current of the class B3 is three times that of the class B5.
The circuits of the (obsoleted) models 353 & 354 analyzers are made to accommodate a current signal from the class B5 sensor.
