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. The string of sensors is installed inside the casing with all the sensor cables passing to the surface where they are connected to Terminal Boxes or Dataloggers.
