为了应用电阻应变仪测试外力,从而提高外力的测试精度和测试效率,解决千斤顶、拉伸机在施工现场校正的问题。四川省建工局建筑科学研究所对传感器进行了探讨。通过两年来的试制和试用,设计、制造成功了适用于建筑工业的荷载传感器(以下简称传感器)。它同目前其他行业的传感器相比较,主要作了以下改进:1.传感器内径增大,粗钢筋可从中穿过; In order to apply resistance strain gauges to test external forces, thereby improving the test accuracy and test efficiency of external forces, the problem of correcting jacks and stretchers at the construction site is solved. The Institute of Construction Science, Sichuan Construction and Construction Bureau discussed the sensors. Through two years of trial production and trial operation, load sensors suitable for the construction industry (hereinafter referred to as sensors) have been successfully designed and manufactured. Compared with other sensors in other industries, the main improvements are as follows: 1. The inner diameter of the sensor is increased, and the thick steel bar can pass through;
