Embodiment

[0028] Embodiment: The measuring product is a vibrating cylinder pressure sensor, and the transducer sheet is a piezoelectric sheet. The piezoelectric sheet is pasted on a non-sensitive part, and pasted on a sensitive part as a control.

[0029] The piezoelectric element is pasted on the position where the non-sensitive part of the sensitive body of the vibration cylinder pressure sensor can feel the vibration signal. The structure of the sensitive part and the non-sensitive part of the vibration cylinder pressure sensor is integrated. One surface is insulated from each other, the piezoelectric sheet is a cuboid, the length direction of the piezoelectric sheet is the same as that of the sensitive part of the vibration cylinder pressure sensor, and the piezoelectric sheet is rigidly pasted on the non-sensitive part. The piezoelectric sheet is pasted on the non-sensitive part of the sensitive part of the vibrating cylinder pressure sensor, and the distance from the sensitive part...

Abstract

The invention belongs to the technical field of sensors and various measurement products by utilizing piezoelectric elements for achieving a work motivation or signal pickup function, and particularly relates to a pasting method of a piezoelectric piece of the sensors and the various measurement products by utilizing the piezoelectric elements for achieving the work motivation or signal pickup function. The pasting method solves the problem that measurement accuracy is reduced because the piezoelectric piece is pasted on sensitive portions. According to the pasting method, the piezoelectric piece is pasted on non-sensitive portions of the sensors and the various measurement products. The pasting method has the advantages of improving measurement accuracy and stability of the sensors and the various measurement products by utilizing the piezoelectric elements for achieving the work motivation or signal pickup function.

Description

technical field [0001] The invention belongs to the technical field of measurement products using a transducer sheet to realize the function of work excitation or signal pickup, in particular to a method for pasting the transducer sheet of a measurement product using a transducer sheet to realize the function of work excitation or signal pickup. Background technique [0002] Existing transducers usually include piezoelectric sheets, strain gauges, etc., and measurement products that use transducers to realize work excitation or signal pickup usually include sensors, transmitters, and force-sensitive components. [0003] However, the transducer sheet of the existing measurement product that uses the transducer sheet to realize the work excitation or signal pickup function is pasted on the sensitive part, and this method reduces the measurement accuracy of the measurement product. Specifically, for the piezoelectric sheet and the pressure sensor, the influence of the piezoelec...
