Measuring Module 

The U15-DIGITAL series measuring module includes the following functions: 

-

 

Measures  the  oxygen  partial  pressure  in  connection  with  a  separate  series  A  or  C 
sensor 

-

 

Output of measured value 0 to 20 mA, switchable to 4 to 20 mA. 

-

 

Generation of alarms 

 
The module is parameterized after the installation, if necessary, and will operate permanently 
with these settings. 
 

Note: 

In order to implement extensive changes and to display measured values, the "METROTEC 
U15 App" for Android Smartphones is required. 

 

3.3 

Sensor 

Depending on the version, the measuring module requires a separate extractive oxygen sensor 
or an inline sensor to carry out its functions.  
Connecting  the  sensor:  See  section  "Connection  Diagram"  as  well  as  separate  operating 
instructions of the sensor.
