YPF Series Diaphragm pressure gauge diaphragm pressure gauge for measuring a certain corrosive, non-pressure or negative pressure solidification or crystallization of a variety of fluid media. Corrosion resistance depends on the film material. Accuracy: 2.5 Ambient temperature: -40 ~ + 70 ℃ relative humidity less than 90%. Temperature: Temperature deviation from 20 ± 5 ℃, its temperature is an additional error of less than 0.04% / ℃. Working position: vertical installation. Protection class: compliance with IP64. Pressure P effect instrument technical performance in line with the industry standard JB / T5491-91 "diaphragm pressure gauge," the provisions of the principles of structural diaphragm pressure gauge when measuring medium in the diaphragm, the diaphragm pressure gauge wholesale produce ammonia deformation, compression pressure gauge measuring only sealing hydraulic system, to form a P- △ P pressure. When the diaphragm is rigid enough hours of ammonia pressure gauge selection, then △ P is small manufacturer of ammonia pressure gauge, pressure gauge pressure measurement system formed near the pressure in the measuring medium pressure due to divide the table by filling sealing system was used as delivery pressure of the medium, because the temperature coefficient of volumetric expansion of the seal, so that the pressure receiving portion with pressure meters and temperature indication is also increased, and the temperature affect the amount of sealing liquid expansion coefficient, the stiffness of the diaphragm and the pressure receiving portion temperature. Especially for low-range pressure gauge, the effect is more pronounced. General provisions of the pressure receiving portion temperature error of not more than 0.1% / ℃. Therefore, the overall impact of the diaphragm pressure gauge temperature is normally provided by general-purpose instrumentation and temperature affect the amount of pressure on the diaphragm assembly unit temperatures affect the amount of the sum of both.
