Digital Inclinometer
Since 2003, RST’s Inclinometer systems have had the shortest overall length available for a given base length compared to competitive inclinometers.
With a minimum negotiable casing radius of 1.93 m, RST’s Digital MEMS Inclinometer can still traverse a smaller radius bend than all other inclinometers available in the industry. A local microcontroller in the probe manages data collection, applies precision digital calibration, and provides a fast settling time which results in very efficient data collection.
The RST Digital Inclinometer App functions as the data collector. The app is designed for field personnel to easily configure and collect readings from the inclinometer probe.
Digital In-place Inclinometer
RST’s new, MEMS Digital In-Place Inclinometer (IPI) System is designed to reliably measure lateral movement in and around dams, embankments, landfills, landslides, piles, piers, retaining walls, and abutments, particularly when continuous remote monitoring is required. It provides an early warning for movements, essential for protecting life and equipment.
Each IPI employs MEMS accelerometer sensors housed inside a 28.6 mm (1.125 in.) diameter, watertight, stainless steel enclosure. The sensor body is rigidly connected to a 25.4 mm (1.0 in.) diameter bay rod which establishes the length of the IPI. Multiple IPIs are assembled with pivots allowing for sensing of displacement over discreet, configurable intervals. Wheel assemblies centralize the pivot point and establish the azimuth of each IPI. They are available in sizes to fit 70 mm (2.75 in.) or 85 mm (3.34 in.) O.D. inclinometer casings.
The sensors are read through a connected signal cable designed to chain together multiple sensors. A data logger is used to monitor the deflection of each sensor on the digital bus. If necessary, an alarm can be triggered when movement reaches a threshold rate or magnitude.
Designed for ease of installation, serviceability and fast delivery, RST’s In-Place Inclinometer System comes standard for both biaxial and uniaxial in one model.
Measurand ShapeArray (SAA)
ShapeArray is an integrated, inclinometer-style instrument that measures deformation in soil and structures in real-time. This patented shape-sensing, technology can be used vertically, horizontally, or in an arc to automate lateral deformation, settlement, or convergence measurements in tunneling applications.
ShapeArray’s design—rigid stainless steel sensorized segments connected by flexible joints—is durable and allows for simple installation from its shipping reel. Every segment of ShapeArray contains a triaxial MEMS tilt sensor, a microprocessor, and a digital temperature sensor. ShapeArray data are available in real-time, enabling engineers and designers to reduce risk and save money by making smarter, faster decisions.
