Based on your previous focus on the conventional coaxiality adjustment of LVDT sensors in hot runner scenarios, here are three simpler, tooling-free adjustment methods:
Hand Resistance Method: Loosen the sensor mounting bracket, manually push and pull the probe without any jamming, then tighten the screw. Suitable for general injection molding scenarios with low precision requirements, this can be completed in 1 minute.
Signal Extreme Value Method: After powering on, fine-tune the sensor position to find the center point where the zero-point output voltage is closest to 0V, then tighten it. No additional measuring tools are needed, and it is suitable for most common operating conditions.
Flexible Connector Compensation Method: Directly connect the probe and needle valve using a universal flexible connector. The float of the connector compensates for minor coaxial deviations, eliminating the need for repeated calibration and significantly reducing the operational threshold.
These methods are simple to operate, require no professional tooling, and can quickly meet the coaxiality requirements of most hot runner scenarios.
