MEMS Tilt Beam

A Tilt Beam consists of a highly accurate MEMS sensor housed in a fully sealed enclosure which is mounted on a lightweight rigid GRP beam. This can be mounted onto the structure using special anchors. The GRP beam has a very low coefficient of thermal expansion meaning that thermal affects are minimised. The can be mounted horizontally or vertically and are best used as chain of beams that can pick up differential displacement over the chain.

The design of the beam and end fixings means the beam can easily be cut to any length on site to accommodate any unexpected changes or constraints.

Each unit is individually calibrated to provide the ultimate in system accuracy and repeatability. It can be used in conjunction with a hand-held readouts or automatic data acquisition systems.

Configuration Options

• Beam Length: 0.5, 1, 2, or 3 m with 50 x 50 x 6 mm dimensions.
• Supply Input: 8-15 V DC
• Output Signal: RS-485/Digital Bus as Sine of angle.
• Cable: Type 800 - Multi-core with braid, 2 x twisted pair, braided, PUR sheath.

Applications

• Monitoring tilt in retaining walls, diaphragm walls, concrete dams, party walls, structures and bridge piers
• Differential displacement within tunnels
• Monitoring of displacement of structures during compensation grouting

Features
