I’m seeking expert advice on how to solve the problem with the gauge shown in the image

As shown in the video, the meters kept getting damaged. How can this be fixed? The medium used is liquid alkali at a concentration of around 32 percent. Plunger pump. 423
The instantaneous pressure shock is quite high; try using a pressure gauge with a larger range, such as one rated at 10 MP
Pulse eliminator added at pump outlet； Replace the table itself with a seismic-resistant one ； The range of the gauge is a bit small; switch it to 1.6 MPA.
In such cases, it is first necessary to prevent the medium from corroding the pressure gauge, as well as to reduce the impact of pressure fluctuations on its service life. Recommendations are as follows: 1. Use a sealing fluid pack to prevent corrosion by the medium. (Glycerin is generally used for sealing oils.) 2. Use a shock-proof pressure gauge.
Add a pressure gauge buffer tube, replace the pressure gauge with a shock-resistant one; if that still doesn’t work, add a pulse damper as well
Add a pressure gauge bend and replace it with a high-range pressure gauge.

First, check whether there are any problems with the plunger pump in this area, and whether there are any leaks in the pump or pipes. The pressure sometimes drops to almost 0; by listening carefully, it’s possible to determine if there is a leak or if there is steam or nitrogen leaking from somewhere nearby. If it’s confirmed that the operating conditions here are normal, then there’s no need to install a pressure gauge here; instead, consider installing a pressure gauge at the end of the material flow path
