When to choose a dry pressure gauge?

　　In some applications, Glycerine filled pressure gauge may not be an ideal gauge because its features may be excessive. Dry pressure gauges are mainly used in industrial machines including air compressors. It is very suitable for environments where mechanical vibration is not a problem and there is almost no moisture. A sufficiently low temperature will cause moisture to turn into ice, which will cause the meter to fail completely.

　　Although dry gauges are generally cheaper than Glycerine filled pressure gauges, they may cost more in the long run if they are used in incorrect applications. The glycerine-filled pressure gauges can absorb vibration and pressure peaks, which will reduce the possibility of poor performance or failure. The low failure rate means that less money is spent on alternatives.

　　The pressure ranges of liquid and dry pressure gauges are equal to each other, but in some cases, Glycerine filled pressure gauge can be used in a higher range. Choosing the right meter is the key to saving money.

　　In short, it is always a good thing to understand the environment required by the meter to ensure that you choose the right meter. It is also good to remember the advantages and disadvantages of each instrument. Each operation is different and may require specific meters.
