Oil filled seismic pressure gauge is introduced, and matters needing attention

Oil filled seismic pressure gauge is a kind of pressure gauge, its working principle as well as pressure gauge, it is through the form of sensitive element ( Bourdon tubes, bellows, bellows) Elastic deformation, the pressure deformation by the transformation of movement in table to Pointers, cause the hands to display the pressure. It is the oil filled to the normal pressure list, oil-filled main purpose is to reduce the pointer in relatively large variations in pressure buffer to zero, so that we can effectively ensure the sensitivity of pressure gauge. General pressure table filling oil is glycerin and silicone oil. Models: PG22 avncpg type: 1 half steel radial oil filled pressure gauge structure: radial type cover circle: flange type, flat panel material: SS304 / brass tooth head: 1/4 & quot; BSP other optional surface diameter: 63 mm shells: S304. Base: brass other optional pressure range: 0 - 10 mpa /公斤,平方厘米( Can be customized) Accuracy: + 2 - 1. 6 - 2% table: PC other optional protection grade: IP65 ( Dustproof, moisture proof, waterproof) Instrument for everybody below says the need to pay attention to the following four points: 1. After a period of use with pressure, pressure gauge movement deformation and wear, hard to avoid can appear some pressure gauge can produce all kinds of errors and failures. In order to guarantee the accuracy of its original without distortion, dissemination should be replaced in a timely manner, to ensure that the correct, safe and reliable. 2. Pressure gauges need to clean them regularly. Because the interior of the pressure gauge is not clean, will increase the wear parts, thus affecting its normal work, serious can make the pressure gauge failure, scrap. 3. In the pressure on the installation of pressure gauge, according to the JJG52 - 1999 rules, it a calibration cycle ship no more than half a year. 4. Pressure parts of the medium wave, frequent use, the accuracy of the demand is higher, and more strict with safety factor, will test cycle shorten appropriately according to the specific situation.
