China's most powerful testing equipment, Haojie Pressure Differential Positive and Negative Sensor

China's strongest testing equipment Haojie pressure differential positive and negative sensor China's strongest testing equipment Haojie pressure differential positive and negative sensor China's strongest testing equipment Haojie pressure differential positive and negative sensor positive and negative micro pressure sensor/transmitter< br/> Characteristics of Haojie Electronic Differential Pressure Sensor/Transmitter
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 one liter. The height
The anti-interference circuit system independently developed by Haojie Electronics
The shell is made of imported aluminum alloy and is durable
The shell structure of Haojie Electronics differential pressure sensor is humanized and designed, and the connection port only uses diameter The compression cock structure and the smallest thread assembly facilitate the disassembly and assembly when measuring small pressures
Before assembling the square pressure differential sensor, high-density silicone was used to coat the connecting surface and four feet were used on the four feet. A small nut is fastened to improve the moisture resistance of the sensor
It is widely used in boiler air supply underground ventilation, central air conditioning, duct wind power, building automation and other power and coal industry pressure processes that have air pressure requirements for laboratory fire engineering Indoor air pressure control field.
Therefore, it is also called wind pressure difference sensor, air pressure difference sensor, pipe wind pressure difference sensor, indoor air pressure difference sensor, etc.
