Product description

The DPD pressure transmitter is designed to measure either differential pressure or air volume flow via the two inputs. By connecting a Pitot tube set, air velocity readout can be enabled enable air velocity readout.

The measured values are transmitted through the two analogue outputs and via Modbus RTU communication protocol, ensuring compatibility with various systems and facilitating data integration. The output types can be set according to their requirements, with options including 0-10 VDC, 0-20 mA or 0-100% PWM.

The device features a 7-segment LED display for visualizing measurements, offering convenient real-time monitoring. Also, all parameters of the DPD can be adjusted and monitored remotely via Modbus RTU.
A typical application for this transmitter is monitoring the volume flow of supplied and extracted air in ventilation systems or AHUs.

The supply voltage is 24 VDC, and the pressure range is from 0 to 1.000 Pa, making it suitable for a wide range of HVAC applications requiring precise measurement and control of air pressure and flow.

Additional specifications and description

Differential pressure, air volume flow or air velocity?
The DPD pressure transmitter (or sensor) is capable of measuring the differential pressure in two different locations simultaneously. This functionality enables users to calculate either air volume flow or air velocity based on the measured data.
For calculating air volume flow based on the K-factor of the fan, users can utilize the PSET-PVC-200 or PSET-QF-200 connection set types. These connection sets provide the necessary components and parameters to accurately determine air volume flow based on the specific characteristics of the fan being used. Additionally, these connection sets can also be utilized for measuring differential pressure when required.
To calculate air volume flow based on the duct cross section or air velocity, users can employ the PSET-PTS-200 or PSET-PTL-200 connection sets. These facilitate the calculation of air volume flow or air velocity based on the dimensions of the duct cross section and the measured air velocity.
By selecting the appropriate connection set based on the specific requirements of the application, users can effectively utilize the DPD pressure transmitter to measure and calculate air volume flow or air velocity in HVAC systems with accuracy and precision.  Dual pressure sensor with Pitot tube
LED display
The measured values are transmitted via the analogue outputs and via Modbus RTU communication. The two values are indicated alternately on the 7-segment LED display. The display can be disabled via Modbus RTU.
How does it work?
The DPD pressure transmitter is equipped with two analogue outputs, each capable of transmitting measured values of either differential pressure, air volume flow, or air velocity in a proportional manner.
By default, the sensor operates within a range of 0 to 1,000 Pa, with the analogue outputs configured to transmit 0 V at 0 Pa and 10 V at 1,000 Pa. This default setup ensures compatibility with standard measurement requirements. However, users have the flexibility to adjust various parameters, including the measurement range, output types and other settings, via Modbus RTU communication.
Heat Recovery Unit
The DPD pressure transmitter provides the capability to measure air volume flow in two distinct locations simultaneously, making it ideal for monitoring both supplied and extracted air volume in various systems such as ventilation systems or Heat Recovery Units (HRUs). This dual measurement functionality enables comprehensive monitoring and control of airflow within these systems, facilitating efficient operation and maintenance.
This sensor can be connected to internet via a Sentera internet gateway. This makes it possible to log data or to adjust settings remotely.
Easy to connect
The screw terminal block facilitates the connection of the supply voltage, the two outputs and Modbus RTU communication. The required supply voltage is 24 VDC. The ground terminals of the power supply (V-) and output (GND) are internally isolated, necessitating the use of a 4-wire cable for connection. Most 24 VDC power supplies are equipped with protective measures against short circuits, overloads, and overvoltage, enhancing the safety and reliability of the installation. Employing a 24 VDC supply voltage further enhances the safety and reliability of your setup.
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 both indoors and outdoors.
