Triaxial tilt sensor STSL

XYZRS-485TTL

Product Introduction
The STSL is a compact, low-power, multi-parameter dual-axis inclinometer designed by RUICOM Technology for industrial field-control applications. It simultaneously measures tilt angle, oscillation frequency, oscillation amplitude and center offset, making it suitable for structural monitoring of towers, bridges and other industrial installations.
