Based on your previous focus on thermal cycle life testing of hot runner sensors, the actual usage time corresponding to the thermal cycle life of a hot runner sensor has a clear industry reference range:
Under normal operating conditions, the lifespan of a typical K-type thermocouple hot runner sensor is 3-5 years. Under suitable environmental conditions and with proper maintenance, high-quality platinum-rhodium alloy or ceramic-encapsulated PT100 type sensors can operate stably for more than 10 years.
From the perspective of thermal cycle count, the thermal cycle life of a hot runner sensor typically corresponds to more than 4 million injection molding production cycles, with some high-end models reaching 8 million cycles without performance degradation.
