To measure pore water pressure in the soil, earth/rock-fill foundations and concrete structures, we have EPP-30V. It is a vibrating wire piezometer that is 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 is provided for an easy cable connection. Using the grouting technique these piezometers can be mounted at different levels in a borehole.
Piezometer - heavy duty
Used for embedment in soil, rockfills, concrete for pore pressure monitoring; observation well for water level monitoring
Water level/pore pressure
0.2, 0.35, 0.5, 0.7, 1.0, 1.5, 2.0, 3.5, 5.0, 10.0 MPa; specify
Thermal cycling (-20 to +80°C), Pressure cycling (2000 cycles), individually temperature compensated, reverse pressure test, individually calibrated providing high accuracy & repeatability
Hermetically sealed with electron beam welding
IP-68, water resistant up to its full range
