Description：
A, use:
YB - 150 - a precision pressure gauge is mainly used to check the ordinary pressure gauge used in industry, but also at the scene of the technology of precise measurement of copper alloy and alloy steel material non-corrosive, crystals, the solidification of medium pressure.
The instrument in the scale line set with mirror ring type (type B), in the use of more clear accurate readings.With zero device (type B)
Second, the precision pressure gauge structure principle:
Instrument by the pressure system, transmission mechanism, an indicating device and the shell.Pressure elastic element after the special craft processing, make its performance is stable and reliable, with high precision of transmission mechanism after debugging, to ensure accurate indication precision.
Instrument working principle is: when the measured medium pressure acting on the elastic element, make its produce elastic deformation, displacement, amplified by rod drive transmission mechanism, the measured pressure by indicating device instructions.
Three main technical indicators, precision pressure gauge:
Measuring range, accuracy grades, and characteristics
model | Spring tube material | Measuring range (MPa) | Precise level | Structural characteristics of |
YB-150A | Tin phosphor copper chrome vanadium steel | 0 ~ 0.1;0 ~ 0.16;0 ~ 0.25;0 ~ 0.4;0 ~ 0.6;0 ~ 1;0 ~ 1.6;0 ~ 2.5;0 ~ 4;0 ~ 6;0 ~ 10;0 ~ 16;0 ~ 25;0 ~ 40;0 ~ 60; | 0.4 | The mirror |
YB-150B | 0.25 | Mirror zero |
Using the environment conditions: 5 ~ 40 ℃, relative humidity is not more than 80%, and the environment vibration and pressure source can not influence the fluctuation of the accurate reading of the instrument.
Temperature: using the environment temperature deviations from 20 + / - 3 ℃ (type A) and 20 plus or minus 2 ℃ (type B), the additional error 0.4% / 10 ℃ temperature must be taken into consideration
Weight: 1 kg (type A) 1.4 kg (type B)
