Product description

Dual Measurement Capability: The HPD series can simultaneously measure differential pressure in two distinct locations.

Measurement Range & Options: It operates within a range of 0 to 10,000 Pa. It can calculate air volume flow based on the fan's K-factor, and air velocity readings are available when an external Pitot tube connection set is used.

Flexible Power Supply: The sensor requires either a 24 VDC or 24 VAC supply voltage.

Flexible Outputs & Configuration: Measured values are transmitted via two output channels (selectable between 0-10 VDC, 0-20 mA, or 0-100% PWM) and Modbus RTU communication. All parameters are adjustable via Modbus RTU.

Primary Application: It's mainly used for monitoring the volume of supplied and extracted air in ventilation systems or Air Handling Units.

Robust Design: The sensor features a surface-mountable enclosure with an IP65 rating, providing protection against dust and moisture for reliable performance in various environmental conditions.

What Can This Sensor Measure and Calculate Simultaneously?
This sensor measures differential pressure [Pa] in two different locations simultaneously. Based on the measurements, 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 optional 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 optional connection set type PSET-PTS-200 or PSET-PTL-200. HPD with PSET-PVC
 
How Do the Analog Outputs Function?
This sensor has two analogue outputs. Each output transmits the measured differential pressure, air volume flow or air velocity proportionally. The default range of this sensor is 0 to 10.000 Pa. By default, each output transmits 0 V at 0 Pa and 10 V at 10.000 Pa. This range, the output types and all other settings can be adjusted via Modbus RTU.
 
How Can Measured Values Be Retrieved and Configured?
This sensor measures air volume flow in two different locations simultaneously. It can be used to monitor the supplied and extracted air volume in ventilation systems or Heat Recuperation Units (HRU).
 
What Are the Key Applications?
To obtain the measured value from this sensor, there are two options. Either read it from the Modbus registers or via the analogue output. The latter proportionally transmits the measured pressure difference, air flow or air velocity. The standard range of this sensor is 0 to 10.000 Pa. By default, the output is 0 V at 0 Pa and 10 V at 10 kPa. This range, output type (0-10 VDC / 0-20 mA / 0-100% PWM) and all other settings can be adjusted via Modbus RTU.
 
What Are the Power Supply and Wiring Details?
The supply voltage, both outputs and Modbus RTU communication can be connected via the screw clamp terminal block. 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.
 
What Are the Sensor's Physical and Durability Features?
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.
