Diaphragm pressure gauge

 Diaphragm pressure gauge for measuring a certain corrosive, pressure or negative pressure of non-coagulating or non-crystalline variety of fluid media. Corrosion resistance depends on the membrane material. Diaphragm pressure gauge [1] Structural principle:? Instrument by the measurement system (including flange joints, corrugated diaphragm), transmission indication institutions (including connecting rod, gear transmission, pointer and dial) and housing (including case and Hood) and other components. Instrument case is splash-proof structure, with good tightness, it could protect its internal organs from contamination ingress. Action principle instrument is based on the elastic element (diaphragm measuring system) deformation. Measured medium under pressure, forcing the diaphragm to produce the corresponding elastic deformation - displacement, through the link set by the drive transmission mechanism and to zoom in, will be measured by the value of the fixed gear pointer on the dial It is indicated. Diaphragm pressure gauge main technical indicators Accuracy: 2.5 Ambient temperature: -40 ~ + 70 ℃; relative humidity less than 90% temperature: Temperature deviation from 20 ± 5 ℃, its temperature additional error of less than 0.04% / ℃ Operating position: vertical mount housing Protection class: IP64 · scale range, dimensions and weight scale range models bearing unit case outer diameter dimension D1 D Weight kg YPF-100A 0 ~ 0.06,0 ~ 0.1,0 ~ 0.16 0 ~ 0.25,0 ~ 0.4, 0 ~ 0.6,0 ~ 1,0 ~ 1.6,0 to 2.5, from -0.1 to 0, -0.1 to 0.06, -0.1 to 0.15, -0.1 to 0.3 -0.1 to 0.5, -0.1 ~ 0.9, -0.1 ~ 1.5, -0.1 ~ 2.4MPa φ85 φ100 1.6 YPF-100B YPF-100B-F φ115 YPF-150A φ85 φ150 1.8 YPF-150B YPF-150B-F φ115 YPF-100B YPF-100B-F 0 ~ 1.6,0 2.5,0 ~ 4,0 ~ 6,0 ~ 10 ~, 0 ~ 16,0 ~ 25,0 ~ 0 ~ 40 * -1.6, -2.5 ~ 0, ~ 4-0, -6 ~ 0, -10 to 0, -16 to 0, -25 0, -40 ~ 0 ~ 0.8 * -0.8, -1.2 ~ 1.2, ~ 2 -2, -3 to 3, -5 to 5, -8 ~ 8, -12 ~ 12, -20 ~ 20 * KPa φ160 φ100 2.9 YPF-150B YPF-150B-F φ160 φ150 3.2 * 0 ~ 40, -40 ~ 0. ± 20KPa standard pressure unit size D, 1 to φ85. . ◆ disadvantages advantages: 1 overload performance is good; 2 linear; 3 adapted to measure absolute pressure, differential pressure; 4 small, affordable; 5 can be used for thick slurry measurements..... Disadvantages: 1 Seismic, impact resistance good; 2 maintenance difficulties; 3 low pressure was measured...
