Product Features

The stainless steel diaphragm pressure gauge refers to the structural characteristics of the original diaphragm pressure gauge and is developed with a corrosion-resistant micro 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 joints, bellows boxes, etc.), a transmission mechanism (including a pull rod mechanism, a gear transmission mechanism), indicator components (including pointers and dials), and a housing (including a case, lining ring, and glass). The working principle of the instrument is based on the elastic deformation of the free end of the bellows box under the action of the measured medium, which is then transmitted and amplified by the gear transmission mechanism. The measured value is gradually indicated on the dial by the pointer fixed on the gear shaft. The structure is equipped with an over protection device to prevent the deformation of the bellows box due to overload. There is also a zero adjustment device, which can easily adjust the zero position.
