YE-100B, YE-150B Stainless Steel Diaphragm Box Pressure Gauge

Instructions:
The stainless steel diaphragm pressure gauge is a micro pressure gauge with corrosion resistance developed based on the structural characteristics of the original diaphragm pressure gauge. Applied to equipment such as boiler ventilation and gas pipelines, measuring the micro pressure and negative pressure of various gas media in processes with high corrosion resistance requirements. Ideal supporting products for domestic users to achieve localization of similar instruments in imported advanced foreign technology equipment.

structural principle
The instrument consists of a measuring system (including connectors, bellows, etc.), a transmission mechanism (including a pull rod mechanism, gear transmission mechanism), indicator components (including pointers and dials), and a housing (including a case, dial, and glass). The working principle of the instrument is based on the elastic deformation of the free end of the corrugated film box under the pressure of the measured medium, which is then amplified by the gear transmission mechanism. The measured value is gradually indicated on the dial by the pointer fixed on the gear shaft. There is also a zero adjustment device that can easily adjust the zero position.
