Tilt Measurement Instruments

Measurement of tilt is an important parameter in the monitoring of structures, slopes and the influence of construction activity in the environs of the Works. Originally, tilt technology was based on either resistive pendulum sensors or electro-mechanical servo accelerometers originally used in inertial guidance. We use solid state MEMs in our tilt devices which gives increased reliability, faster response times, lower power requirements and options for innovative logging strategies.

Inclinometer System

An inclinometer system is used to manually monitor installed inclinometer tubes. The system comprises a wheeled probe which runs within the orthogonal keyways of the tube, connected to a cable and cable reel which is connected in turn to a logger readout. In practice, the probe is lowered to the base of the installation and a pair of readings are taken in X and Y axes with the results stored within the logger. The probe is then pulled up in successive 0.5 metres and further sets of readings are taken. This is then repeated with the probe rotated 180 degrees. In this way a profile of the inclinometer tube can be constructed using tilt angles over 0.5 m segments allowing changes in this profile with time to be displayed in tabular and graphical format.

Portable Tiltmeter

The portable tiltmeter is a unit used to determine the tilt of ceramic or bronze tiltplates which are attached to structures.

Pendulum Tilt System

The Pendulum Tilt System is for monitoring tilt of tall structures & high rise buildings and for measurement & monitoring of relative displacement in concrete and masonry dams.
