Load Cell Type Soil Pressure Gauge
Load Cell Type Soil Pressure Gauge
A TML load-cell-type soil-pressure-gauge is a robust geotechnical instrument from Tokyo Measuring Instruments Laboratory (TML) that uses strain gauges to measure pressure in soil, converting it into an electrical signal for monitoring construction, dams, tunnels, and ground stability, known for precision, durability, and resistance to lateral pressure. These stainless-steel devices, like the KDG-PA/KDH-PA models, are designed to be installed directly in soil to capture stress, ensuring long-term structural safety.
The sensor core is a strain gauge, a sensitive resistor that changes resistance when stretched or compressed. When soil pressure acts on the gauge, it deforms the sensing element, creating mechanical stress. The strain gauge detects this stress, and the change in resistance is converted into a precise electrical signal. Then this signal is measured by a data logger or strain meter, providing real-time pressure data. TML (Tokyo Measuring Instruments Laboratory) is one of the only few manufacturers of this type of sensors useful in geotechnical engineering and investigation
KDG-PA/KDH-PA Load Cell type Soil Pressure Gauge 200kPa to 2MPa
These are all-stainless steel soil pressure gauges each 100 mm in outer diameter. They are load cell-type soil pressure gauges that are less sensitive to side pressure. KDG-PA and KDH-PA models are available with differing cable exit directions.
