The invention discloses a high-precision resonant mode quartz temperature sensor with a plurality of arrow-shaped vibrating arms. The high-precision resonant mode quartz temperature sensor with the arrow-shaped vibrating arms aims to solve the problems of large volume, fixed thermosensitive quartz resonator, complex mounting structure, slow response speed and the like of an existing temperature sensor. The high-precision resonant mode quartz temperature sensor with the arrow-shaped vibrating arms comprises an integrated packaging part and a thermosensitive quartz resonator, wherein the integrated packaging part is filled with helium gas; the integrated packaging part comprises a pipe cap and a pipe seat; the pipe seat comprises an insulator, a first pin and a second pin; the thermosensitive quartz resonator comprises a base region and n vibrating arms, and n is an even number not less than four. According to the high-precision resonant mode quartz temperature sensor with the arrow-shaped vibrating arms, the mechanical strength of the thermosensitive quartz resonator is improved, a parasitic vibration mode in a conventional structure is reduced, structures are simple to support, fixand mount, high cost rate is achieved, and more importantly the precision, response speed, repeatability and long-term stability of the sensor are improved. The high-precision resonant mode quartz temperature sensor with the arrow-shaped vibrating arms has low working frequency, low power consumption, high precision, high response speed, clean frequency spectrum and high anti-interference capability.

The invention relates to a method for manufacturing a tiny-pore plate by using a wave flat belt, comprising the following steps of: overlapping a wave-shaped belt (2) and a flat belt (3) to form a wave flat belt (1); fixing the starting end of the wave flat belt (1) on a center shaft (4); winding the wave flat belt (1) on the center shaft (4) for a plurality of circles by taking the center shaft (4) as a center; and fixing the termination end of the wave flat belt (1) after the winding so as to obtain the tiny-pore plate (5).
