RRX ELECTRONIC EXTENSOMETER

A complete range of single and multi-height electronic extensometers with local and remote reading capability, providing highly accurate but simple, low-cost monitoring of rock movement in mines and tunnels

The units are tough and rugged and are spring loaded to allow installation at various orientations, with a 75mm range per anchor, providing a reliable and flexible solution and a total range of up to 300mm when using a four height extensometer

Every RRX can be read individually utlising the RRT-PR Hand-held read-out unit, or up to 1200 units can be connected together by a single twin-core cable to provide a mine-wide monitoring solution that can be read at any point along the line. Can be incorporated into a full Remote Reading Telltale system for automatic reading via a surface PC
