Differential pressure transmitter | 0 - 1000 Pa | 24 VAC-VDC


Product description

HVAC sensor to measure differential pressure in the range of 0 to 1.000 Pa. The supply voltage is 24 VAC or 24 VDC. This sensor can also measure air volume flow or air velocity. The measured value is available via the analogue output and via Modbus RTU communication. The output type is selectable. The four LED indicators provide a visual indication of the transmitter status and the measured values. The differential pressure range and all other settings can be adjusted via Modbus RTU.

Additional specifications and description

 
Differential pressure, air volume flow or air velocity?
This sensor 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 or PSET-QF-200. This 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 connection set type PSET-PTS-200 or PSET-PTL-200.
 
Visual indication
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 enabled. 
 
How 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 1.000 Pa. By default, the output transmits 0 V at 0 Pa and 10 V at 1.000 Pa. This range, the output type and all other settings can be adjusted via Modbus RTU. The output type can be adjusted via Modbus RTU: 0-10 VDC / 0-20 mA / 0-100 % PWM.
 
Reduced installation time
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. This sensor can be supplied with 24 VDC or with 24 VAC. It is intended for 3-wire connection. The ground of the output (GND) is internally connected to the ground of the supply voltage (V-). Make sure not to connect this common ground to other devices that are powered by a DC voltage.
 
High quality
The enclosure is made of high-quality r-ABS VO (UL94) plastic. This material is heat resistant, very tough 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.
