Allows demand-based volume flow control in order to optimise energy consumption in ventilation systems. Differential pressures of at least 1 Pa can be controlled to allow minimal volume flows at the lowest duct pressure and energy consumption.

• Controlling the return air in fume cupboards and controlling the supply and return air in laboratories, clean rooms, hospital wards and operating theatres using a VAV box or a damper and flow probe
• Static measurement of differential pressure based on the capacitive method of measurement
• Zero point can be calibrated using software
• djustable end values of the differential pressure measuring range
  • 50…150 Pa
  • 100…300 Pa
