Horizontal Inclinometer mempunyai tujuan untuk mengetahui profil penurunan seperti monitoring penurunan dan timbunan dibawah tangki penyimpanan, atau pondasi LNG (mis), Bendungan, dan lainnya.
Sistem Inclinometer Horizontal terdiri dari Casing inclinometer, Sensor Horizontal, control Cable, Pull cable, dan Alat Baca.
Casing is installed in a horizontal trench or borehole with one set of grooves aligned to vertical. If the far end of the casing is not accessible, a
dead-end pulley and cable-return pipe are installed with the casing.
The probe, control cable, pull-cable, and readout are used to survey the casing. The initial survey establishes the profile of the casing. Subsequent
surveys reveal changes in the profile if ground movement occurs.
The Digitilt probe employs a forcebalanced servo-accelerometer to measure tilt in the plane of the probe wheels. During a survey, tilt measurements are obtained at half-meter or 2-foot intervals as the probe is drawn from one end of the casing to the other.
The probe is then reversed end-forend and drawn through the casing a second time. Tilt measurements from the reversed probe are used to eliminate any error due to sensor bias and to generate checksums for validating the survey.
Settlement and heave are calculated as L(sine q1 - sine q0), where L is the measurement interval, q1 is the current tilt, and q0 is the initial tilt.
Settlement profiles are generated by summing displacements and plotting them.
Differential Settlement: Horizontal inclinometers provide full profiles of differential settlement.
Simple Operation: Horizontal inclinometer surveys are simple and relatively quick. Unlike other profilers, there are no reservoirs or pressure
sources to adjust and maintain.
Proven Reliability: The Digitilt inclinometer probe has earned a world-wide reputation for high precision and durability.
