Abstract: This paper discussed the unbonded elastic wire resistance type osmometer and vibrating wire type osmometer in aspects such as research and development history, production status, engineering practices and problems. It concluded that both the two types of sensors would be applicable in seepage pressure monitoring for earth-rockfill dam and concrete dam. According to production status and engineering practice lessons of monitoring instruments in China, some measures and suggestion to guarantee the quality of dam safety monitoring were put forward.

摘要： 通过对国内差阻式和振弦式渗压计研发历史、生产现状、工程实践以及存在问题的讨论，认为两种仪器都适用于土石坝和混凝土坝渗流监测，并基于国内监测仪器生产现状和工程实践的经验教训，提出了保证大坝安全监测质量的措施建议。
