STRAIN GAUGE PIEZOMETER SGP-3400 SERIES
The SGP-3400 Series of strain gauge piezometers are designed for monitoring soil pore pressure or changes in water level and are also suitable for dynamic monitoring such as pumping tests.
They are accurate, highly-reliable and suitable for use in the harsh environments often found within civil engineering including water wells, boreholes, dams, reservoirs, rivers, tanks or any other body of water.
Description
The sensor is housed in a robust stainless steel sealed body with a porous filter tip, which are available in different porosities to suit specific site conditions.
It comprises a highly sensitive stainless steel diaphragm onto which a Wheatstone bridge strain gauge is mounted and connected to a signal-conditioning board to convert to a 4-20mA output within the piezometer housing.
When liquid pressure is applied to the diaphragm it causes the Wheatstone bridge strain gauge to output a signal, which is directly proportional to the applied pressure.
They are available in standard or vented versions and can be read by simple hand held readout units or integrated into a data logger for fully automated monitoring.

DRIVE-IN PIEZOMETERS WP-3400 & SGP-3500 SERIES
In stock
Drive-in piezometers, also referred to as push-in piezometers, are designed for installing in soft clays, organic or fine grained cohesionless soils typically with a SPT-N value less than 10. They are available with a CPT fitting or 1” BSP thread.
Depending on the depth and type of soil, they can either be pushed directly into the soil from ground level to the required depth or pushed into the base of a CPT test or drilled borehole.

HPS-3500 (Hanging) and IPS-3000 (Inverted) Pendulums are used to measure the tilt or rotation by measuring the relative internal horizontal displacement of points along a true vertical line. Each has a tensioned, stainless steel wire and the effects of the earth gravitational forces to guarantee a perfectly vertical line between a fixed point and a tensioning mechanism. Typical applications include concrete dams, bridges and high rise buildings.
