Digital Bus In-Place Vertical Inclinometer System

Digital Bus Vertical In-Place MEMS Inclinometer Systems are designed to measure lateral movement of soil and rock or deflection

Description

Digital Bus Vertical In-Place MEMS Inclinometer Systems are designed to measure lateral movement of soil and rock or deflection of man made structures such as piles or retaining walls, when remote and continuous monitoring is required.

These inclinometers consist of one or more MEMS inclinometer sensors housed inside a 31.75 mm (1.25 in.) diameter, water-tight, stainless steel enclosure. Each sensor is separated from the next by stainless steel rods and wheel assemblies; however, the entire system is connected by a digital bus system which consists of one single cable running the length of the entire chain of connected sensors; this eliminates the need of a separate cable for each sensor and reduces the amount of cable to be managed. Rod lengths can be varied to alter the bay length and sensors can be concentrated in areas of expected movement. An optional analog cable system is also available.
