Capsule Pressure Gauge
Brief DescriptionYE-150 capsule pressure gauge is suited to measure micro pressure and negative pressure which won't have corrosive effect upon copper alloy in non-hazard occasions, the gas is widely used in devices such as boiler ventilation and gas piping, etc This gaug
DetailsStructure Principle
This gauge consists of measuring system (including joint, bellow sylphon), driving device (including pull rod mechanism and gear drive), and indicating part (including needle and dial plate) and casing (including case, ring gasket and meter glass). Working principle is that under the medium pressure, the free end of the sylphon will be elastic deformation, then driven by gear drive mechanism and amplified, and the needle fixed on the gear shaft will indicate the measuring value on the scale plate. There is also zero-adjusting device which is easy to adjust zero position.

Working environmental temperature: -25-55℃
Temperature effect: No more than 0.4% / 10℃
Relative humidity: not more than 80%
When working temperature deviation is 20±5℃, the temperature additional error is not more than 0.4%/10℃.
