Product name：CYW-150B/CYW-153B Stainless steel differential pressure gauge Manufacturer：Shanghai NO.4 Automation Instrumentation Factory Classification：Pressure gauge > Stainless steel differential pressure gauge Sales manufacturer：Shanghai Automation Instrumentation Co., Ltd Release date：2017-5-4

Overview

The CYW-150B/CYW-153B stainless steel differential pressure gaugeis mainly used in liquid level measurement, filter monitoring, flowmeasurement, chemical process, food industry and other field. The pressuregauge structure is made of stainless steel, with strong corrosion resistanceand erosion effect of working environment, reasonable integral structuredesign, advanced process, good stability, long service life, novel appearance,and can bear high pressure and low pressure.

Structure and principle of CYW-150B/CYW-153B

Instrument withdouble bellows structure, that is, two bellows were installed in the"workers" on both sides of the symmetrical position of the bracket.The upper and lower ends of the "working" font bracket are themovable end and the fixed end respectively, and the middle is connected by aspring piece; the two bellows are parallel and connected with the high and lowpressure joint on the case respectively by a conduit; Directly mounted on thefixed end of the bracket and connected to the movable end of the bracket bymeans of a tie rod; the dial is fixed directly to the gear transmissionmechanism.

The workingprinciple of the instrument: Based on the sensing element using two corrugatedpipes with the same stiffness, so in the same measured medium to force them toproduce the same concentration of force on the activities of the bracket, thespring on both sides of the role of the moment Does not produce disturbances,so the bracket is still in its original position, so that the gear transmissionmechanism does not move, so that the pointer still refers to the zero.

When applyingdifferent pressures (generally higher than the low pressure side), the force ofthe two bellows acting on the movable support is not equal, so that thecorresponding displacement is generated and the gear transmission is driven andamplified, and the value will be indicated.
