pressure, air volume flow or air velocity?
measures differential pressure [Pa]. Based on this
measurement, air volume flow [m³/hr] or air velocity [m/s] can be calculated.
To calculate air volume flow based on the
K-factor of the fan, use the connection set type PSET-PVC-200
This optional connection set can also be used to measure differential pressure.
To calculate air volume flow based on the duct
cross section [cm²] or air velocity [m/s], use the
optional connection set type PSET-PTS-200
This pressure transmitter offers a clear, visual
indication of the differential pressure level via the green, yellow and
red LED. The green LED indicates that the pressure level is within
range. When the pressure level enters the alert range, the yellow LED lights
up. Red means: differential pressure out of range. The LEDs can also indicate
the status of the air volume flow or air velocity. The second green
LED indicates the sensor status. It is activated
when power supply and Modbus RTU communication are
does it work?
This sensor has one analogue
output. It transmits the measured differential pressure, air volume
flow or air velocity proportionally. The default range of this sensor is 0
to 2.000 Pa. By default, the output transmits 0 V at 0 Pa and 10 V at 2.000
Pa. This range, the output type and all other settings can be adjusted via
The supply voltage, the analogue output
and Modbus RTU communication can be connected via the cage clamp
terminal block. They eliminate the need for routine maintenance and
guarantee a reliable contact for solid or stranded wires. The supply voltage is
24 VDC. The ground terminals of the power supply (V-) and output (GND) are
internally not connected. This means that a 4-wire cable is
required to connect this sensor. Most 24 VDC power supplies offer protection against short circuit, overload and overvotage. A 24 VDC supply voltage increases the safety and reliability of your installation
The enclosure is made of high-quality r-ABS
VO (UL94) plastic. This material is heat resistant, very though and
offers good protection against impacts. The pressure connection
nozzles are made from Aluminium. The sensor
enclosure offers an IP65 protection against ingress of
dirt and water. This sensor can be wall-mounted.
