Product description
3.1
Functional description
The differential pressure sensor is used to monitor the differential pressure for climate control applica-
tions, e. g. raised floor cooling, cold aisle housing, etc. It supplies the measured pressure values to the
connected CMC III PU. The differential pressure sensor has an identification that allows it to be detect-
ed automatically by the CMC III PU.
3.2
Proper use
The CMC III Analogue Differential Pressure Sensor is used only to monitor the differential pressure for
climate control applications with the supplied air hose, e. g. in a cold aisle. It may be used only together
with the CMC III PU. Any other use is not permitted.
