Pressure switches are mainly sensitive element 2.1 bellows features: durability and resistance to vibration than the Bourdon tube well, then off difference adjustable range, gems pressure switches, the main materials are stainless steel, phosphor bronze, high pressure switch, the relatively high price but measurable pressure range is small, up to 40MPa (CB33) 2.2 diaphragm Features: excellent corrosion resistance, pressure switches, the main materials are NBR, fluorine rubber, such as CS, CL series, are using such sensitive element. Pressure switch quick and easy selection of excellent automation have included. Second, the comparison table electrical contacts, mechanical pressure switch good accuracy advantage l l l long life and high repeatability, no patch, no contact corrosion resistance l l l set flexible visual display l drift is small pressure switch, Tour Well, gas pressure switch is provided by TU Technology Co., Ltd. Beijing tour. Pressure switches, swim well, gas pressure switch is Beijing Tour En Technology Co., Ltd.
