Product Description
DU0/5 and DU0/25 Differential Pressure Sensors
Application
Differential pressure sensors with power output DC 0 V to 10 V for
measuring the pressure or differential pressure in ventilation and air
conditioning systems.
The sensors convert the measured pressure/differential pressure into
a proportional voltage signal between DC 0 V and 10 V.
The voltage signal can be used directly for closed-loop control and/or
display.
■DU0/5 has three adjustable pressure ranges: 0 mbar to 1 mbar,
0 mbar to 3 mbar or 0 mbar to 5 mbar.
■DU0/25 has three adjustable pressure ranges: 0 mbar to 10 mbar,
0 mbar to 16 mbar or 0 mbar to 25 mbar.

Connection
Installation
The installation position is to be selected so that the permitted conditions for the differential pressure
sensor are maintained (see Section Technical Data).
The system must be depressurized before installation and removal.
The differential pressure sensor should not be installed at a point where it may be affected by high
pressure pulses.
The installation position is variable. The recommended installation position is vertical with the
pressure connections at the bottom (factory calibration).
!NOTICE
If the differential pressure sensor is not installed vertically, a zero point reset should be performed.
The sensor is installed on a mounting bracket on a vibration free surface, with the pressure connec-
tions at the bottom.
The connection hose for the higher pressure is connected at P1 for measuring the differential
pressure. The connection for the lower pressure is connected at P2.
The hose connections at the ventilation duct and at the differential pressure sensor are to be
connected depending on their function: for measuring differential pressure, overpressure or low
pressure.

A connection set is provided for connecting the differential pressure sensor.
►Drill a hole for the ventilation duct Ø 16 mm.
►Insert a rubber grommet.
►Push the connection nozzle into the grommet.
►Cut the PVC hose to the required length, attach it to the connection nozzle and connect the differ-
ential pressure sensor.
NOTE
The pressure transmitter should be installed a minimum distance of 10 mm from magnetic materials.
If this is not possible, an error of up to -1 Pa may occur when the pressure transmitter is mounted on
sheet steel.

Commissioning
Adjusting the measuring range
Zero point reset button (2)
A zero point offset may occur due to a strong thermal change in the sensor environment. This means
that the displayed measured value is not zero when there is no pressure.
Pressure deviations are set to zero by pressing the zero point reset button (2).
!NOTICE
After electrical commissioning, press and hold the button on the depressurized device until the LED
(1) flashes. If the LED (1) remains lit, the reset has not worked due to pressure in the device.
