METHOD AND DEVICE FOR DETERMINING THE TEMPERATURE OF A PIEZO-ELECTRIC ELEMENT

摘要

The present invention relates to a method and a device for determining the temperature of a piezo-electric element. This method and this device can be used for determining the capacity of a piezo-electric element at a desired temperature as well as for determining the desired temperature of the piezo-electric element on the basis of both the determined capacity and the capacity variability relative to the temperature. This method and this device can therefore be used for easily determining the temperature of the piezo-electric element without influencing the function thereof.
