How to re-fill the oil into the pressure gauge

The general reasons of the oil leaking are: The aging of the sealing gasket, Instrument mounted on equipment vibrates frequently or excessively, the loosing of the bezel, Man-made accidental instrument falls to the ground causing the deformation of the watch cover and so on. So must find the reason of the leaking before refill the oil.

If you want to re-fill,, you have to ask to the supplier to know whether it is silicone oil or glycerin in it. Generally, there is an oil injection hole at the top of the shell of the shock-proof pressure gauge, which is sealed with a rubber plug. You can pull the rubber plug out, (take care not to destroy the rubber plug). Then you can fill the silicone oil or glycerin in and cover the rubber plug after filling.

What is a barometer

A barometer is a scientific instrument used in meteorology to measure atmospheric pressure. Pressure tendency can forecast short term changes in the weather. Numerous measurements of air pressure are used within surface weather analysis. Barometers and pressure altimeters (the most basic and common type of altimeter) are essentially the same instrument, but used for dif...

Use and Maintenane of Bimetallic Thermometer

The length of the bimetallic thermometer protective tube immersed in the measured medium must be longer than that of the temperature sensitive element. Generally, the immersion length is greater than 100 mm, and the immersion length of 0-50 (?) C range is greater than 150 mm, so as to ensure the accuracy of the measurement. Bimetallic thermometers should avoid collision...

Liquid Thermometer

Working liquids in liquid thermometers are used to sense temperature changes, So there are three requirements for it: First, the temperature range of liquids should be wide, that is to say, its freezing point should be low and its boiling point should be high. Second, the volume expansion coefficient should be large. Third, liquids should be pure, not stained with glass,...
