Negative pressure -60kPa vacuum gauge: installation strategy

The installation and repair of a negative pressure -60kPa gauge is critical to its proper operation and measurement accuracy. In terms of installation, the first thing to do is to choose a suitable installation location, because there is a potential pressure gradient in the vacuum chamber, it should be avoided to install the vacuum gauge in an area with large pressure changes to ensure the accuracy of the measurement results. At the same time, it should be noted that the connecting flange should be as short as possible, and the number of seals should be reduced to a minimum to prevent pressure leakage due to connection problems and affect the measurement accuracy. For example, during installation, if the connection flange is too long or there are too many seals, the pressure indicated by the gauge may be higher than the actual pressure in the vacuum chamber, resulting in measurement errors.
