Haojie Electronic Pressure Differential Sensor/Transmitter Device characteristics
Imported from the United States high-precision silicon piezoresistive positive and negative differential pressure cores, the accuracy is one level higher than that of its peers, and the resolution has also reached a level of 1 liter
Independently developed by Haojie Electronics Anti-interference road system
The shell is made of imported aluminum alloy and is durable
The shell structure of Haojie electronic differential pressure sensor is humanized design, and the connection port uses a diameter compression plug structure with the smallest thread for easy assembly. Measuring small pressure requires disassembly
Before assembling the square differential pressure sensor, high-density silicone was used to coat the connecting surface and four small nuts were used to fasten the four feet to improve the moisture resistance of the sensor.
It is widely used in indoor air pressure control fields such as boiler air supply underground ventilation, central air conditioning, duct wind power, building automation and other laboratory fire engineering where the pressure process in the power and coal industry has air pressure requirements.
Therefore, it is also called wind pressure difference sensor, air pressure difference sensor, pipe wind pressure difference sensor, indoor air pressure difference sensor, etc.
