Cảm biến đo áp suất chất lỏng GEOKON 4500H-350KPA     

Standard Piezometers (VW) | Model 4500S(V) · 4500SH · 4500AL(V)

The Model 4500 Standard Piezometer is designed to measure fluid pressures such as ground water elevations and pore pressures when buried directly in embankments, fills, etc. Also for installation inside boreholes, observation wells and standard (>19 mm diameter) piezometer riser pipe. The Model 4500SH is designed with a heavy duty housing for pressures that exceed 3 MPa. The Model 4500AL is designed for low-pressure ranges. The vented version (ALV) provides automatic compensation for barometric pressure changes. Thermistors are included to measure temperatures.*
