NP785 Ultra-Low Differential Pressure Transmitter – ±5 mbar (2 inH2O)

Description

The NP785 Ultra Low Dif. pres. DIN Rail, RS485, 4-20mA or 0-10V output, ± 5 mbar (2 inH2O) is an ultra-low differential pressure transmitter designed for HVAC (heating, ventilation and air conditioning) systems, cleanrooms and flow measurement processes in industrial environments. It measures overpressure, underpressure and small differential pressure variations in neutral, non-corrosive gases with high accuracy, delivering a linear output signal proportional to pressure.

It stands out for its bidirectional measurement, covering ranges from vacuum to positive pressure. Configuration is flexible thanks to the USB connection and dedicated software, making it easy to adjust parameters to each application’s requirements.

The NP785 transmitter has a rugged ABS/PC housing for DIN rail mounting and nickel-plated fittings compatible with 4 and 6 mm ID pneumatic hoses, ensuring a secure, long-lasting installation in demanding environments.

For connectivity, it offers an analog output configurable as 0-10 V or 4-20 mA, plus RS485 communication with Modbus RTU protocol for integration into industrial monitoring and control systems. Its design includes temperature compensation for long-term stability and meets EMC standards, ensuring a high level of robustness, reliability and performance in critical industrial applications.
