Model: P-B30AI-300K-V product name: diaphragm pressure gauge Table diameter: 76mm range: -30~0KPa installation mode: radial interface thread: 3/8PF accuracy rating: 2.5%F.S.(customizable)Bellows pressure gauge (also called micro pressure table) because of the pressure sensor is composed of two pieces of corrugated metal diaphragm, so called bellows pressure gauge, typically used to measure the tiny pressure in the gas or vapor.Dongguan Pyle resistance instrument co., LTD is a company specializing in the production of pressure instrument production enterprise, our company production of bellows pressure gauge with over-voltage protection device, can to a certain extent, prevent damage of stress caused by the instrument.Because each different at high altitude area, and using the instrument working environment temperature is different, because of its extremely sensitive pressure indicator, which will cause the pointer is not zero, we in the design and manufacture of bellows pressure gauge with zero device, can be suitable for all kinds of working environment.PIONEER bellows pressure gauge is the use of advanced technology and excellent craft, widely used in pipe terminal, according to the gas pressure is suitable for measuring the micro pressure and negative pressure of the gas. It is widely applied in gas burning equipment, coating systems and all kinds of industrial gas heating system, gas, natural gas pipeline project, the high pressure bellows pressure gauge is also applicable to coating equipment and spraying machinery, air pipeline, gas pipeline, burning device and other similar devices, such as building adjustable dividers, gasification station, gas station position, burner, boiler, oven, oven, kitchen utensils and appliances and other industrial equipment gas measuring display instrument.Advantages: 1. Beautiful appearance and superior quality.2. Complete specifications, with overpressure protection and zero adjustment device.3. Reasonable price and quick delivery.4. Product quality guarantee for one year, we have excellent and perfect after-sales service.5. Accept large small orders and undertake OEM and ODM orders, which can be customized according to customer requirements.
