MEMS Horizontal Inclinometer

MEMS Horizontal Inclinometer

The Model 6155 MEMS Horizontal In-Place Inclinometer consists of a string of MEMS (Micro-Electro-Mechanical Sensor) tilt sensors mounted on lengths of stainless steel tubing, which are linked together by universal joints. A spring-loaded wheel assembly, designed to engage the grooves of conventional inclinometer casing, is located at each joint.
