摘　　要：振弦式渗压计是土建测应力较为先进的高精度传感器之一。设计和实现了一种能够实时监测的渗压测量模块,较好地解决了该传感器测量时信号微弱、距离远、干扰大、校准要求高等难点;同时设计了一种实用高精度热敏电阻器测量模块,实现了对振弦式渗压计的校正。该模块与同类的监测仪器相比,具有结构简单、精度高、扩展性好、抗干扰性强等优点。By now,vibrating wire osmometer is one of the advanced high-precision sensors which are used in the measuremeat of stress in foreign countries. A real-time measurement module is designed in order to solve the problems when using vibrating wire osmometer, such as weak signal, long measure distance, big interfere. A practical measurement module for high-precision thermistor is designed. The calibration of vibrating wire osmometer is carried out. Compared with the similar monitor instrument, this module has many advantages, such as simple structure, high-precision, good scalability and high anti-interference.
