The invention proposes devices and methods for detecting and tracking the number of sterilization cycles that a component of a system undergoes during reprocessing. A sterilization cycle count tracking device includes a bimetallic coil made of two metals of different thermal coefficients of expansion connected to an extended limb to move a wheel integrated with a mechanical counter. The method of tracking the number of sterilization counts involves incrementing the mechanical counter using the pointer connected to the bimetallic coil when the device is subjected to cycling in a specified temperature range. The resultant count indicates to the end user the number of cycles completed. The method provides a means of notifying the user about the potential degradation of a sterilized part and for planning early replacements. The device and method can be used across industries as the device can be mounted onto any part undergoing thermal cycling.
