Ultra Low Differential Pressure Transmitter Ideal for industrial environments, clean rooms, HVAC, filtration systems, and pressurized stairwells, 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. ✓ Available nominal ranges: ± 50 Pa (± 0.2 inH2O) to ± 68 mbar (± 1 Psi) ✓ Ranges fully configurable by software within rated range ✓ Temperature compensated for higher stability at low pressures ✓ Output signal DC 0 to 10 V or 4 to 20 mA and slave Modbus RTU, in one-only-model ✓ Resistant to overpressure ✓ Auto-zero Key ✓ Diagnostic LED 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. 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. Measurement Range Proof Pressure* Burst Pressure Line Pressure Accuracy Effective sensor resolution Operating Temperature Power Supply Voltage PWR terminals: 12 Vdc to 30 Vdc USB cable power: 4.75 Vdc to 5.25 Vdc Internal protection against reverse polarity Dimensions Housing * Proof Pressure is defined as the maximum pressure at which the device can be subjected and which still maintains its performance within specifications after returning to the operating range. ** Maximum Range at 25°C.
