Explosion-Proof Valve Testing with SinceVision Laser Displacement Sensor
In the lithium industry, precise testing of explosion-proof valves is essential before welding the core top cover. Positive and negative testing ensures that bulges or sags do not introduce errors into subsequent processes. SinceVision’s SD33-85 laser displacement sensor offers high-precision, non-contact detection by measuring the range values to accurately determine the orientation of the explosion-proof valve. This intelligent solution optimizes manufacturing quality and ensures reliable performance in every step of the process.
