LY-100 pressure gauge calibrator

1. Structural Characteristics
The pressure gauge calibrator is a new type of instrument newly developed and patented by our factory. The instrument has a booster device and a manually operated pressure pump can obtain higher pressure by gently pressurizing it. It has advanced design, easy operation, light performance, stable pressure rise and fall, uniform working pressure, high measuring range, and the instrument is equipped with multiple calibration joints (uniform quick joints). Multiple pressure gauges can be installed at one time. The upper gauge is locked and does not require a wrench. It can be installed quickly and conveniently for work efficiency. High advantages. This calibrator is an ideal and practical measuring equipment for pressure gauge calibration by measurement departments at all levels and factories, mines, enterprises and institutions.
2. Main technical parameters
Measuring range: (/㎡).
, Accuracy: Depends on the accuracy of the standard table. Generally, a . or . grade standard table is used.
Working medium: clean instrument oil or transformer oil.
, Sealing: After fully removing the air, pressurize until the overpressure sealing test is carried out. The pressure drop value in the last minute starting from the minute is less than.
, Number of table connectors: one (one of which is installed with a standard table).
, Connector thread specifications:. .
, appearance dimensions.
, weight.
3. Structure and working principle
The overall structure of this pressure gauge calibrator mainly includes: hand pump, supercharger, boost switch, return inspection switch, zero return switch, pressure gauge holder, The pipeline system (including high-pressure pipeline system, low-pressure pipeline system, oil inlet pipe, oil return pipeline), oil tank, etc.
This machine uses the standard pressure gauge as the standard device based on Pascal's principle to perform pressure gauge calibration by comparing the calibrated gauge with the standard gauge.
This machine uses a hand pump to generate normal pressure and pressurize it through the supercharger inside the machine to obtain a higher working pressure. Therefore, it has the characteristics of flexible operation and lightness.
