Description

We have EPP-30V to measure pore water pressure in soil, earth/rock-fill foundations, and concrete structures. It is a vibrating wire piezometer made of stainless steel and hermetically sealed under a vacuum of 0.001 Torr. These sensors have a built-in thermistor for temperature measurement and a surge arrester for protection from lightning. A glass-to-metal seal solder pin connector provides an easy cable connection. These piezometers can be mounted at different levels in a borehole using the grouting technique.
