Product description
This differential pressure sensor measures within a range of 0 to 10,000 Pa. It can also measure air volume flow and, when combined with an external Pitot tube (such as the PSET-PTS set), air velocity.
For simplified connectivity, the device uses 24 VDC Power over Modbus (PoM), which transmits both power and communication through a single UTP cable.
A 7-segment LED display and four additional LED indicators provide visual feedback on measured values and device status. All settings, including the differential pressure range, are fully adjustable via Modbus RTU communication.
Additional specifications and description
What Can This Sensor Measure and Calculate?
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.

How Does the Sensor Provide Visual Feedback?
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.

What Are the Power Supply and Wiring Details?
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.
