Micro differential pressure sensor-PN51D

Product introduction

The PN51D series differential pressure sensors/transmitters detect differential or gauge pressure and convert this pressure value into a proportional electrical output for intelligent building energy management systems to measure the precise pressure and flow required for building pressurization and air flow control. The pressure value can be set on the spot by the built-in dialing switch of PN51D series products.
- range: 0 ~ ± 10Pa/ 0 ~ ± 10,000Pa
- accuracy: ± 1.0%
- Various pressure units can be switched
- LCD backlit digital display or no display
- Start automatic zero calibration
- Response time can be adjusted on site by the built-in code switch (0.5s ~4S)
- Manual key differential pressure zero calibration
- Adopt imported micro pressing core
- Rotating mode is fixed on the mounting back plate (the mounting plate and the host machine are separated, so that step-by-step installation can be implemented)
