PCT No. PCT/CH93/00216 Sec. 371 Date Apr. 29, 1994 Sec. 102(e) Date Apr. 29, 1994 PCT Filed Sep. 2, 1993 PCT Pub. No. WO94/06025 PCT Pub. Date Mar. 17, 1994.The sensor comprises at least one quartz body (1) sectioned from a quartz crystal, an optical fiber connected to the quartz body in at least one given length, and means for detecting changes in length of the optical fiber which are caused by piezoelectrically caused changes in shape of the quartz body in an electric field. It is shown how the mostly undesired temperature dependence of the sensor measurement signal can be influenced and, as the case may be, even eliminated in a purely passive manner by a mixture of the two independent piezoelectric coefficients d11 and d14 which contribute to the piezoelectrically caused change in dimension of the quartz body.
