Application and Precautions of Digital Air Differential Pressure Transmitter
Air Differential Pressure Transmitter could be called as Air Differential Pressure Sensor or Transducer, it is widely used in electric power, coal industry pressure process, laboratories with air pressure requirements, indoor air pressure control field for fire engineering, as well as the fields such as boiler air supply, underground ventilation, central air conditioning, air duct wind, building automatic control, etc. it can also replace the traditional remote pressure gauge and need remote pressure data transmission.

This GE-923 Digital Air Differential Pressure transmitter Sensor is produced for ventilation system..
Application field of digital Air Differential Pressure Transmitter
Generally, the digital remote pressure gauge can choose 4-20mA, 0-10V, 0-5V remote signal or RS485 signal output, which based on standard Modbus RTU communication protocol.
The digital remote Air Differential Pressure Transmitter will generally use four digit digital display to display the real-time differential pressure, and the pressure signal can be transmitted remotely, usually its transmission distance could be longer than 1000m. It is mainly used in boiler air supply, underground ventilation, central air conditioning, air duct wind, building automation and other electric power, coal industry pressure process, laboratories with air pressure requirements, indoor air pressure control field for fire engineering, but also can replace traditional remote differential pressure gauge, remote pressure data transmission and other fields. It have powerful functions, user can change pressure unit, calibrate error, correct filter constant, etc. Generally, RS485 output type also has address setting, baud rate selection and other functions. It is especially suitable for replacing traditional pointer type remote pressure gauge or pressure transmitter with display.
Precautions for digital remote Air Differential Pressure Transmitter
1.The instrument shall be placed in a dust-free and corrosion-free environment; if there are special environmental requirements, the corresponding products in the corresponding environment shall be selected. For example, if for Explosion-proof environment GE-923-EX type flame-proof air micro Air Differential Pressure Transmitter of A.YITE brand should be selected.
2. When the instrument is not in use, turn off the power to avoid electric shock.
3. The proper range of the instrument shall be selected so that the differential pressure transmitter has enough overload capacity, but do not overload seriously, otherwise the sensor will be damaged and the instrument cannot be used.
4. Without professional testing skills and special testing equipment, do not open the cover for maintenance, and do not allow to adjust internal components and replace materials, otherwise the reliability of the instrument cannot be guaranteed.
5. Carry out correct installation and operation in strict accordance with the operation manual.
