SKU: N/A Categories: ,


Ideal for HVAC (Heating, Ventilation and Air Conditioning), clean-room and flow measurement applications, the NP785 is an ultra-low differential pressure transmitter for measuring very small over-pressure, under pressure and differential pressure in neutral, non-corrosive gaseous media. It provides a pressure proportional linear signal output with configurable measuring range via USB using the configuration software.

NP785 can operate bi-directionally, providing the ability to measure differential pressure ranges from vacuum to positive pressure. It is housed in a DIN rail mountable ABS/ PC enclosure and its nickel-plated brass fittings accept pneumatic hoses with 4 or 6 mm internal diameter.

The analog output can be set to either 0-10 V or 4-20 mA while having an RS485 with Modbus RTU communication protocol. Designed for HVAC and industrial environment, the NP785 ensures temperature compensation for longterm stability and complies with EMC standards, providing robustness and reliability for a wide range of applications.

The pressure transmitter includes free NXperience configuration software. This program allows you to explore all the features and details of the devices and communicates through a USB interface, TCP-IP, and NOVUS Cloud. The NXperience is a comprehensive tool that enables a graphical analysis of multiple data, alarm processing, positioning map visualization, performing mathematical calculations and reporting, and exporting data to multiple formats. It also provides device-specific diagnostics and commissioning, making testing and troubleshooting easier.
Also, through NXperience you can create, manage an account and storage your data in NOVUS Cloud.
