摘要： Provided is a Angevin type quartz sensor which is high in measurement sensitivity, suppresses the influence of the surface tension of a sample solution during measurement, and enables an installed quartz resonator to stable oscillate. An opposing surface portion opposes one surface side of the quartz resonator via a housing area and a pouring opening formed in the outside area of the opposing surface portion. Measurement is conducted in a standstill state where the sample solution is filled in the lower side of the opposing surface portion. Since stress due to the surface tension of the sample solution does not act in this state, the quartz resonator can oscillate with reliability. Therefore, the quartz sensor can reduced the thickness of the quartz resonator, which realizes highly sensitive and highly accurate measurement.

摘要： In a sensing instrument using a quartz sensor on whose front surface an adsorption layer for adsorbing a substance to be sensed is formed and which changes in natural frequency by the adsorption of the substance to be sensed, the present invention has an object to quickly detect a trouble of the quartz sensor to prevent an operator from recognizing an incorrect measurement result.In the present invention, a level detecting circuit detecting a signal level of an oscillation output of an oscillator circuit is provided, and after the time for stabilization passes after the power-on time, a computer takes a level detection value therein to compare the signal level and a threshold value. Then, when the signal level is lower than the threshold value, the signal level is determined as abnormal and, for example, the abnormality notification is displayed on a display unit, whereby an operator is notified of the occurrence of the abnormality.
