Ideal for HVAC, 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. The 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 port with Modbus RTU communication protocol.
The NP785 has a digital alarm output, which supports the configuration of the alarm condition, adjustable set points and custom timing, among other functions. It's output can be configured for 0-10 V or 4-20 mA with adjustable range within the sensor limits. It also has adjustable behavior options in case of sensor error. The free downloadable NXperience software offers a quick and intuitive way to configure all of the sensor features. The NXperience software also provides monitoring and diagnostics features.
Designed for HVAC and industrial environment, the NP785 ensures temperature compensation for long term stability and complies with EMC standards, providing robustness and reliability for a wide range of applications.
