How long can a hot runner sensor be used after aging?

The degree of age has a direct impact on how long a hot runner sensor will last. Moderate aging can be used for one to three months, severe aging needs to be replaced right away, and mild aging can be used for three to six months. The following are specific classifications:

Only the component has mildly aged (Slight Drift, Recoverable After Calibration). After calibration, accuracy can restore to acceptable levels. It can still be used steadily for three to six months with correct use and routine calibration, and it usually won't break down unexpectedly.

Moderate Aging (Drift Speed Increased, Accuracy Hardly Acceptable After Calibration): Sensitivity has dropped by 5%–10%, and the diaphragm has some rust. This level can only be sustained for a little time by calibration. Usually, the remaining lifespan is between one and three months. Accuracy may unexpectedly surpass acceptable bounds, necessitating the preparation of replacement parts beforehand.

Severe aging (accuracy still exceeds norms after calibration, or adhesive leakage/signal abrupt changes occur): Internal component damage, seal failure, or diaphragm corrosion are irreversible and may result in total scrapping at any time. Usually, the remaining lifespan is no longer than two weeks. The hot runner may also be harmed by adhesive leaks; replacement is advised right away.

Even minor aging should be planned ahead of time for high-precision items to prevent batch scrap from unexpected accuracy problems.
