Title:
加速度又は圧力測定用の接地絶縁された圧電型センサ
Document Type and Number:
Japanese Patent JP4909284
Kind Code:
B2
Abstract:
The invention describes a sensor comprising an element package 2 including piezoelectric elements with an upper area 6 and a lower area 7. A preload sleeve 3 surrounds the said upper area 6 of the said element package 2, while an insulation sleeve 1 sits between the upper area 6 of the said element package 2 and the said preload sleeve 3. An outer housing 4 partially or fully surrounds the said preload sleeve 3 and the lower area 7 of the said element package 2. An insulation part 5 sits between the said lower area 7 of the element package 2 and the said outer housing 4, whereas the said upper area 6 of the said element package 2, the said insulation sleeve 1 and the said preload sleeve 3 have conical shapes and have conforming surfaces. Due to the conical size of the insulation sleeve 1, the load during a shock measurement is distributed on a larger surface area resulting in a reduced compression of the said insulation sleeve. Thereby, the maximum range of the sensor is increased.
