Ideal for HVAC, cleanroom and flow measurement applications, the NP 785 is an ultra-low differential pressure transmitter for measuring very small pressure variations. The NP 785 measures differential pressures in neutral, non-corrosive gaseous media. It transmits a linear output signal proportional to pressure, with a measurement range that can be configured via USB using the dedicated configuration software.
The NP 785 can operate bidirectionally, offering the possibility of measuring differential pressures ranging from vacuum to positive pressure. Its ABS / PC case is DIN rail-mountable. Its fittings are nickel-plated and accept pneumatic tubes of 4 or 6 mm internal diameter.
The analog output can be set to 0-10 V or 4-20 mA with an RS485 communication protocol with Modbus RTU. Designed for HVAC and industrial environments, it features temperature compensation for long-term stability. The NP 785 complies with EMC standards, offering robustness and reliability for a wide range of applications.
