The DPT series differential pressure sensors from Produal (formerly HK Instruments) are specifically designed for accurate measurements in air and climate control systems (HVAC), such as building management systems, industrial ventilation systems, and cleanrooms, where reliable pressure measurements are essential. In addition, DPT sensors stand out due to their flexibility and ease of use.
How does the DPT sensor work?
The DPT differential pressure sensor uses modern MEMS technology (Micro-Electro-Mechanical Systems), ensuring high accuracy and stability both in the short and long term.
The DPT (Differential Pressure Transmitter) measures the pressure difference between two pressure points, for example before and after a filter or fan. Depending on the model, the measured pressure difference is either converted into an electrical signal (such as 0–10 V or 4–20 mA) or communicated digitally via Modbus to the building management system (BMS).
Key features of the DPT series
- 8 selectable ranges in a single device
- High accuracy, approx. 1% of the measured value
- Automatic zero point correction (AZ) and display depending on the version
- Multiple output signals: analog (0–10 V, 4–20 mA) or digital (Modbus)
Applications
- Monitoring of airflow and fans in ventilation systems
- Monitoring and detection of filter contamination
- Monitoring of overpressure and underpressure in cleanrooms
- Optimization of energy consumption and comfort in buildings
Advantages of the DPT series
- Reliable and stable measurements
- Reduced maintenance thanks to smart technology
- Flexible application due to adjustable parameters
- Easy integration into modern building management systems
