Differential Pressure Sensor Air
Differential pressure transmitter with 8
selectable ranges and Modbus funtionality.
NEMA 4X / IP65 rated enclosure. For
monitoring over-, under or the differential
pressure of air and other non-flammable
and non-aggressive gases. Typical
application in HVAC systems for monitoring
air filters, fans V-belts or fire and smoke
control dampers. Options available with
LCD display and Auto-Zero function.

Remarks
Automated Zero-Point calibration (Auto- Transmitters equipped with the auto-zero calibration are maintenance-free.
Zero)
The auto-zero calibration electronically adjusts the transmitter zero every 10 minutes.The
function eliminates all output signal drift due to thermal, electronic or mechanical effects.
The auto-zero adjustment takes approx. 4 seconds after which the device returns to its
normal measuring mode. During the 4 second adjustment period, the output and display
values will freeze to the latest measured value.
Manual Zero-Point Calibration In normal operation zero-point calibration should be executed every 12 months.
Attention! For executing zero-point calibration the power supply must be connected one
hour before.
• Release both connection tubes from the pressure terminals + and -
• Press the button until the LED lights permanently
• Wait until the LED flashes again and reinstall the connection tubes to the pressure ports

Detailed documentation The separate document Sensor Modbus-Register informs about Modbus register,
addressing, parity and bus termination (DIP1: address, DIP2: baud rate, parity, bus
termination)
In addition to the information on the bus, the following analog outputs are available:
AOU1: differential pressure
AOU2: volumetric flow
The volumetric flow is calculated from the differential pressure, the k-factor and the height.
Factory setting for the k-factor is 1.00 and for the height 330 metres above sea level.
The values of the k-factor and the height can be changed via Modbus or BACnet.
Notes Wiring RS485 Connection via safety isolating transformer.
Parallel connection of other devices possible. Observe the performance data.
The wiring of the line for BACnet MS/TP / Modbus RTU is to be carried out in accordance
with applicable RS485 regulations.
Modbus / BACnet: Supply and communication are not galvanically isolated. Connect earth
signal of the devices with one another.
