Special instrument for packaging machinery sealing test - pressure sensor - pressure sensor characteristics and price
PTJ501-1 micro pressure sensor / transmitterHaojie electronic gas pressure sensor / transmitter features:
1: Imported high-precision silicon piezoresistive pneumatic core in the United States, the accuracy can be higher than the peers, and the resolution is also one litre.
2: Anti-jamming road system independently developed by Haojie Electronics
3: The outer casing is made of imported aluminum alloy, which is durable.
4: Haojie electronic micro pressure sensor shell structure humanized design, the connection port is only φ8mm diameter compression type cock structure and M10*1 small thread assembly is convenient to measure and reduce pressure to disassemble.
5: Before assembling the square differential pressure sensor, the high-density silica gel was used to coat the joint surface, and four small nuts were used to solidify the four feet to improve the moisture resistance of the sensor.
It is widely used in power control such as building automation, dust pressure control of dust collectors, pressure process in coal industry, laboratory with air pressure requirements, container sealing inspection, and indoor gas pressure control for fire protection engineering.
