Differential pressure and temperature sensor

The ACW-PTMxP has been specially designed for monitoring HVAC installations: CMV and air handling units.

It monitors the pressure difference at the filter inlet and outlet, as well as one or two remote temperature sensors. It is also equipped with an on/off input (logic or counting).

By regularly measuring the negative pressure caused by filter clogging, preventive maintenance can be ensured.

Measurements are transmitted regularly by radio (Sigfox or LoRaWAN technology). If the threshold is exceeded, an alert is sent to the user. The data can be viewed on any type of IoT* platform.
