Insulated, waterproof, durable, piezoresistive pressure gauge

Insulated, waterproof, durable, piezoresistive pressure gaugeIt is a sensor for measuring seepage water or static water pressure, used to measure the pore water pressure or seepage pressure inside structures, suitable for measuring backfill or in-situ pore water pressure, uplift pressure, water level or fluid pressure in containers.

Insulated, waterproof, durable, piezoresistive pressure gaugeAdopting high-precision digital circuits, it outputs standard 485 digital signals or standard current signals, and can simultaneously measure temperature values. It has the characteristics of 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.
