NBPLANN100MGUNV

Pressure sensors, transducers and NBPLANN100MGUNV are important elements in the field of modern automation and measurement technology. Some of its usage applications and working principles are described below.

Application Field

The NBPLANN100MGUNV is a type of pressure sensor, transducer, designed for monitoring differential pressures with a differential pressure range of -100 mbar to +100 mbar. It is suitable for air, non-aggressive and non-aggressive gasses. It is mainly used in industrial automation and control, such as plant engineering, refrigeration, air conditioning, ventilation, pumps and compressors. As it is designed for use in hostile environments, it is vibration resistant, dustproof, explosion-proof, waterproof and resistant to EMC-induced interference.

Working Principle

The NBPLANN100MGUNV operates on the principle of converting a pressure input or differential pressure into an electrical signal. Pressure is measured by using a diaphragm that is sealed against the sides of the body with O-rings. The diaphragm is in contact with an internal pressure gauge which is a capacitive gauge comprising a quartz crystal oscillator. The diaphragm deflects under pressure, thus changing the capacitance of the oscillator, resulting in a change in frequency that is proportional to the pressure.

The output of the pressure sensor is a 4-20mA current signal and is amplified by an internal amplifier. This signal is then converted into an electrical voltage by an internal converter. The voltage output is proportional to the differential pressure input and is used to control valves or other devices. The pressure is displayed on the LCD, making it easier to monitor the system.

Conclusion

The NBPLANN100MGUNV is a type of pressure sensor, transducer, designed for monitoring differential pressures with a differential pressure range of -100 mbar to +100 mbar. It operates on the principle of converting pressure inputs or differential pressure into an electrical signal which is then converted into a 4-20mA current signal and then into a voltage signal which is displayed on the LCD. This pressure sensor is mainly used in industrial applications and is resistant to hostile environments.
