ABSTRACT OF THE DISCLOSURE: The invention relates to a process for the compensation of temperature variations in devices incorporating two elastic surface wave oscillators, whose oscillation frequencies are mixed so as to supply the difference between these frequencies. The process consists of inserting a delay element into the loop of at least one of the oscillators which introduces a delay which varies with the temperature and whose length is selected so as to balance out the variations of the two oscillators. The invention is more particularly applicable to force and pressure transducers and to accelerometers. Figure 1
