Model: NP785
NP785 Ultra-Low Differential Pressure Transmitter
The NP785 is designed specifically for pharmaceutical cleanrooms, containment suites, isolation rooms, and laminar flow hoods where micro-pressure cascades are vital to prevent cross-contamination. It measures positive, negative, and bi-directional differential pressures with thermal compensation, offering USB re-ranging and simultaneous analog + RS485 Modbus RTU telemetry in a single model.
Key Features
- Ultra-low differential pressure ranges: ±50 Pa (±0.2 inH2O) to ±68 mbar (±1.0 PSI)
- Bi-directional measurement (vacuum to positive differential pressure)
- Dual output capability: 4-20 mA or 0-10 V plus RS485 Modbus RTU in one unit
- Temperature compensated sensor for long-term baseline stability at ultra-low ranges
- Configurable via USB with auto-zero push-button for easy recalibration
- DIN rail mountable ABS/PC housing with nickel-plated brass hose fittings (4 or 6 mm)
