Description
I. directions for use:
The YB-150A precision pressure gauge is mainly used to calibrate industrial pressure gauges. It can also accurately measure the pressure of non corrosive, non crystalline and non solidified media on copper alloy and alloy structural steel at the process site.
The instrument is equipped with a mirror ring (A B type) under the scale line, and the reading is clearer and more accurate in use. And with zero adjustment device (B type).
Two. The structure principle of precision pressure gauge:
The instrument consists of a pressure measuring system, a transmission mechanism, an indicating device and a case. The piezo elastic element is processed by special technology to ensure its performance is stable and reliable. After debugging with the high-precision transmission mechanism, it can ensure accurate indication accuracy.
The working principle of the instrument is that when the pressure of the measured medium acts on the elastic element, it causes elastic deformation and displacement, and drives the transmission mechanism to enlarge through the pull rod, indicating the measured pressure by the indicating device.
Three, the main technical indicators of precision pressure gauge:
Measurement range, accuracy grade and characteristics
Model | Spring tube material | Measurement range (MPa) | Accuracy grade | Structural characteristics |
YB-150A | Tin phosphor bronze 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; 0~4;;;;; | Zero point four | Mirror surface |
YB-150B | Zero point two five | Mirror zero adjustment |
The environmental conditions are: 5~40 C, the relative humidity is not greater than 80%, and the fluctuation of environmental vibration and pressure source has no effect on the accurate reading of the instrument.
Temperature influence: when the ambient temperature is deviated from 20 + 3 A (type 20) or 20 + 2 C (B), the additional error of temperature should be considered.
Weight: 1kg (type A) 1.4kg (B type)
