Title:
METHOD OF COMPENSATING CHARACTERISTIC CHANGE DUE TO TEMPERATURE SURFACE ELASTIC DEVICE AND PRESSURE TRANSDUER
Document Type and Number:
Japanese Patent JPS55153412
Kind Code:
A
Abstract:
An arrangement for temperature compensating transducers including two elastic surface wave oscillators whose frequencies are mixed to produce an output frequency that is a function of a parameter to be measured such as force, pressure or acceleration. A delay element such as a transmission line having a delay that is a function of temperature is inserted into the loop of at least one of the oscillators to balance oscillator frequency deviations resulting from temperature changes.
