Soil Instruments Vibrating Wire W9

The Vibrating Wire Piezometer is designed for accurate and long term measurement of pore water pressures in fully or partially saturated soil and rock.The transducer is made from high quality 316 grade stainless steel and designed to handle pressure ranges from -50 to 4000 kPa. It incorporates an over voltage surge arrestor that oﬀers protection from a lightning strikeThe piezometer may be ﬁtted with either a low air entry sintered steel or high air entry ceramic ﬁlters. A coned nose piece is available for push in installations. An integral thermistor for temperature monitoring is included.
