Measuring module
The PZA series measuring module features the following functions:
-
Measurement of the partial pressure of oxygen in conjunction with a separate Series A
sensor. Select the PZA-MC25-N variant for diffusion-based measurements and the
PZA-MC25-P variant for flow-based measurements (see separate instruction manual for
the Series A sensors)
-
Output of the reading 4 to 20 mA
-
Alarm signals
Following installation, you can adjust the module’s parameters, if required. The module then
remains in continuous operation with these settings.
Please note:
If you wish to make extensive changes and display the measured readings, you will need the
PZA app for Android smartphones. The APP can be downloaded by using the QR code on the
sensor and/or electronics units
3.3
Sensor
To function, the measuring module requires a separate A-series oxygen sensor.
To connect the A-series oxygen sensor, see point 2 under ‘Terminal connections’ and the
separate instruction manual for the A-series sensor.
The chosen A-series sensor and the PZA-MC25 electronic unit are paired together in the
factory. The calibration protocol has both serial numbers printed in the protocol.
Never use non-paired sensors and electronic units. This will result in erroneous measurements.
