Introduction
The DT-HLS-XXX series differential pressure static level gauge is a settlement monitoring instrument developed by Da Tie Detection with a focus on structural health monitoring. Based on years of application experience, this instrument employs high-precision and high-stability silicon piezoresistive pressure sensors, which have undergone linear calibration and full temperature compensation. It is suitable for automated settlement monitoring of large structures such as tunnels, bridges, dams, slopes, railways, and highways.
