Pressure transmitter | display | 125 to 125 Pa | PoM


Product description

Differential pressure sensor with display. The operating range is -125 to +125 Pa. The supply voltage is 24 VDC PoM. It measures differential pressure or air volume flow. Air velocity readout is available by connecting an external Pitot tube connection set: PSET-PTS-200. The 7-segment LED display visualises the measurement. The measured values are transmitted via Modbus RTU. Both Modbus RTU communication and the supply voltage can be connected via one RJ45 connector. The four LED indicators provide a visual indication of the transmitter status and the measured values. A typical application is to monitor air volume flow and the supply of fresh air. 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
The 7-segment LED display visualises the measured pressure, volume flow or air velocity. On top of that, the green, yellow and red LED offer a visual indication of the measured value. 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. 
 
Reduced installation time
One RJ45 connector is all it takes to connect this sensor! Modbus RTU communication and 24 VDC power supply are connected via one UTP cable - we call it Power over Modbus or PoM. All measured values are available via Modbus RTU communication. To facilitate wiring, we recommend to use a Sentera 24 VDC power supply with RJ45 connector. These power supplies also offer protection against short circuit, overload and overvoltage. A 24 VDC supply voltage increases the safety and reliability of your installation.
 
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.
