Use

Focus segment

● Air handling units (AHU), with communication between controller and field devices

and connected to cloud enabling plant digitalization.

● Support of Ecodesign directive ErP 2016/2018 through the use of bus-compatible

sensors for monitoring filters, including cloud visualization.

Field of application

The QBM3700.. Modbus air pressure sensor and I/O extension is used in ventilation sys-

tems and air handling units (AHU):

● To measure and monitor pressure in air ducts and over filters and fans

● On the supply and extract air side

The QBM3700.. is ideally suited for a multitude of tasks in the HVAC industry:

● Measures relative and differential pressure and flow of air and non-aggressive gases

● Available with a differential pressure sensor

● Allows monitoring of pressure or volume flow at two individual points in the system
