Product Overview
Earth pressure gauge (earth pressure gauge) is an embedded pressure sensor mainly used to measure the stress of the soil inside structures such as earth and rock dams, soil lifts, slopes, roadbeds, retaining walls, and tunnels. It is suitable for long-term automated monitoring. The main components of the sensor are made of special steel and can be used in harsh environments. Its performance is excellent, with good accuracy and sensitivity, excellent waterproof performance, corrosion resistance, and long-term stability. After improving cable protection measures, it can be directly buried in compacted soil with high requirements for instruments.
