一种位移传感器和道面弯沉测量设备
摘要：
本实用新型提供一种位移传感器和道面弯沉测量设备，位移传感器中，千分尺具有定尺和动尺；动尺上具有预定数目个动刻度线，每两个动刻度线之间为一个动刻度量程；位移容栅检测传感器，与千分尺固定在一起，具有一个能够对动刻度量程进行测量并得到一个第二长度的测量单元，以及一个能够显示定尺测量测量精度得到的第一长度与第二长度的和数的显示单元；第二长度的精度高于第一长度的精度一个量级；传感器外壳，与千分尺固定在一起。定尺能够通过测量得到一个较低精度的第一长度，由于位移容栅检测传感器能够对动刻度量程进行测量并得到一个第二长度，该第二长度的精度高于动刻度量程所确定的精度至少一个量级。
摘要（英）：

The utility model provides a displacement sensor and a road surface sink measuring device, wherein in the displacement sensor, a micrometer is provided with a fixed ruler and a moving ruler, the moving ruler is provided with a predetermined number of moving scale lines, the distance between two moving scale lines is a moving scale measuring range, a displacement capacitance detection sensor is fixed with the micrometer together and comprises a measuring unit capable of measuring the moving scale measuring range and obtaining a second length and a display unit capable of displaying the measuring precision of the fixed ruler and obtaining the sum of a first length and the second length, the precision of the second length is higher than that of the first length by an order of magnitude, and a sensor housing is fixed with the micrometer together. The fixed ruler can obtain the first length being lower in precision through measurement, and because the displacement capacitance detection sensor can measure the moving scale measuring range and obtain the second length, the precision of the second length is higher than the precision determined by the moving scale measuring range by at least one order of magnitude.
