WebMeasurements from the deepest part of an inclinometer casing have the highest potential for systematic errors due to four factors: (1) instrument warm-up drift being most acute, (2) calibration hysteresis more probable, (3) tendency of the borehole to drift from vertical, and (4) greatest distance from the top reference point. WebMay 19, 2024 · A digital inclinometer system makes use of a traversing type digital tilt sensing probe that is attached to a reel unit. The reel unit is made up of a winding reel that holds the cable and a wireless Bluetooth relay unit that transmits the digital probe data to the readout unit. The Cable Reel Unit also has a rechargeable battery that supplies ... How to Install Digital Inclinometer in a Borehole? Borehole Drilling Start by drilling a 125mm hole around 0.5m more than the planned depth of the inclinometer casing. (Try keeping the hole as vertical as possible) The diameter of the drill hole should facilitate grouting around outside of the casing.
