PTJ501-1 Micro Air Pressure Sensor/Transmitter, Micro Air Pressure Sensor Transmitter

Haojie Electronic Wind Pressure Sensor/Transmitter Characteristics:

1: Imported high-precision silicon piezoresistive wind pressure core from the United States, the accuracy is one level higher than its peers, and the resolution has reached a height of one liter

2: Anti interference road system independently developed by Haojie Electronics

3: The shell is made of imported aluminum alloy material, which is durable and long-lasting

4: The shell structure of Haojie Electronic Wind Pressure Sensor is designed with humanization, and the connection port is equipped with an 8mm diameter compression type plug structure and M10 * 1 small thread assembly, which facilitates disassembly and assembly when measuring small pressures

5: Before assembling the square differential pressure sensor, high-density silicone was used to coat the connecting surface, and four small nuts were used to fix it on all four feet, thereby improving the moisture resistance of the sensor

Widely used in boiler air supply, underground ventilation, central air conditioning, duct wind power, fan engineering inlet and outlet, pipeline wind pressure, building automation and other power and coal industry wind pressure processes, laboratories with wind pressure requirements, and indoor air pressure control fields for fire engineering.
