摘要
差动电阻式传感器基于电阻丝变形与电阻变化率成正比的原理而工作。具有防潮、长期测量、测值稳定、可靠性高、测试原理简单、适用范围广等优点,在我国得到了广泛的应用。本文在阐述此类传感器的工作原理基础上,详细介绍了FWC2000型差动电阻式网络测量系统及其测试原理,此外,还就该测试系统在安全监测中的应用情况作了简介。
The differential resistor sensor works on that the change of the resistor value functions with the distortion caused by the external force. For the advantages of damp-proof performance, long-term detection, high-stability, high-reliability and visualized working principle, it becomes one of the most potential types of earthwork sensors widely used in our country. On the basis of its principle, a high performance automatic instrument for the differential resistor sensor named FWC2000 (one of our company's products) is described in detail. Some application results of FWC2000 are briefly presented in the end.
