The NP785 is an ultra low differential pressure transmitter for measuring very differential pressures 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.
