MEMS Vertical Inclinometer


The Model 6150 Series MEMS In-Place Inclinometers consist 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. The string of sensors is inserted inside a pipe, or a casing installed in a borehole in the ground, with the sensor cable(s) passing to the surface where they are connected to Terminal Boxes or Dataloggers. Several models, including analog, digital, addressable and wheelless versions, are available allowing for optimal configuration based on application and site specifics.
