How to determine the quality of the diaphragm box in a double-flange transmitter?
Thread Content
In the factory, there is a gauge diaphragm box that is dented, but it still has elasticity and the silicone oil is still present. If the load is removed, the gauge also returns to zero. Please, those who understand can explain – can this watch still be used?
If it is determined that there is no leakage of silicone oil, as long as the diaphragm still has elasticity, it can be used weiterhin.
If there is still silicone oil present, it shouldn’t leak; otherwise, it would seep out little by little. It’s recommended to check first (as someone else mentioned above)! Pressure vessels cannot afford the slightest carelessness: lol
Check a few points to see the linearity and such; zeroing is just part of it
