Piezoresistive permeameter for dams

Piezoresistive permeameter for damsPressure resistance type permeameter is a sensor used to measure seepage water or static water pressure, and is used to measure the pore water pressure or osmotic pressure inside structures. It is suitable for measuring backfill or in-situ pore water pressure, uplift pressure, water level or fluid pressure in containers.

Piezoresistive permeameter for damsThe piezoresistive pressure gauge adopts high-precision digital circuits, outputs standard 485 digital signals or standard current signals, and can simultaneously measure temperature values. It has strong anti-interference ability, long-term stability, and reliable sealing. Widely used in civil engineering fields such as architecture, railways, transportation, reservoirs, hydropower stations, dams, tunnels, etc.
