Wireless differential pressure sensor

The wireless differential pressure sensor/pressure monitor is usually installed in the installation room (special solutions available on request). It can be installed and operated in three different operating modes. The wireless differential pressure sensor always monitors the permitted differential pressure (Pa) between:

• Installation room of the fireplace and chimney (SD).
  This requires a negative pressure of at least 4 Pa in the flue gas system.
• Installation room of the fireplace and external pressure (AD).
  For this purpose, a maximum negative pressure of 4 Pa in the installation room is permissible in room air-independent operation.
• Installation room of the fireplace and external pressure (AD).
  For this purpose, a maximum negative pressure of 8 Pa in the installation room is permissible in room air-independent operation.

When the permissible negative pressure prevails, it sends corresponding release signals to the respective receiver.
