Stainless steel diaphragm pressure gauge
Stainless steel diaphragm pressure gauge is a pressure measuring equipment used in industries such as petroleum, chemical, and metallurgy. It is mainly used for micro pressure and negative pressure detection of corrosive gases or liquid media. The shell and pressure system are made of 1Cr18Ni9 stainless steel, which is suitable for scenarios with high corrosion resistance requirements such as boiler ventilation and gas pipelines. This instrument is also used in industries such as aerospace, water treatment, oil and gas extraction and transportation, air conditioning cold chain, food processing, and pharmaceutical production. It is suitable for measuring low and micro pressures of liquids, gases, or vapors that are non explosive, non crystalline, non solidifying, and have no corrosive effect on copper and copper alloys.
The instrument consists of a measurement system, a transmission indicator mechanism, and a housing. The working principle of the instrument is based on the elastic deformation of the free end of the bellows box under the pressure of the measured medium. The core component of the bellows box is usually welded from two circular bellows membranes, sealed internally and evacuated or filled with a specific gas. After passing through the gear transmission mechanism and amplification, the transmission mechanism can mechanically amplify the small deformation of the membrane box, thereby improving the sensitivity of detecting micro pressure. The pointer fixed on the gear shaft gradually indicates the measured value on the dial. The entire measurement and indication process is completed entirely through mechanical structures, without the need for external power supply, making it an inherently safe instrument.
Application: The stainless steel diaphragm pressure gauge can measure the small pressure of liquids, gases, or vapors that have no corrosive effect on copper and copper alloys. The casing and pressure system of the instrument are made of 1Cr18Ni9 stainless steel material. The measurement principle is based on the elastic deformation of the corrugated film box under the pressure of the measured medium, which is then amplified by the transmission mechanism and indicated by the pointer on the dial as the pressure value. Widely used for pressure measurement in industrial sectors such as petroleum and chemical industry. In addition, it is widely used in various industrial fields such as aerospace, energy, medical, food and beverage, HVAC, water treatment, etc., especially suitable for process flows with high corrosion resistance requirements. Stainless steel bellows pressure gauges are suitable for measuring low micro pressures and negative pressures of liquids, gases, or vapors that are non explosive, non crystalline, non solidifying, and have no corrosive effect on copper and copper alloys. The instrument mainly consists of a measuring system (including joints, corrugated film boxes), a transmission mechanism, indicator components (pointers and dials), and a housing.
