Sealing issues of pressure transmitters after filling with oil
Thread Content
1. After evacuating the pressure transmitter and filling it with silicone oil, how can it be sealed to prevent leaks? I am considering using a stainless steel capillary with a diameter of 3 mm and a wall thickness of 0.5 mm to fill it with oil; after that, it will be flattened using tools and then welded at the ends. What tools are available to flatten a stainless steel tube with a diameter of 3 mm and a wall thickness of 0.5 mm, ensuring no oil leakage? 2. Is there any better method of filling oil to ensure a good seal after filling and prevent leaks for good? Thank you
It may require professional manufacturers to carry out the filling; it’s uncertain whether filling it oneself can ensure quality
Our company uses filling systems with steel ball seals; however, over time, the silicone oil inside such seals leaks. What can be done to ensure no leakage? Are there any good solutions?
I have a dedicated filling device; the question is, how can I seal it after filling to ensure no leaks for ever?
