Description 1.1 Introduction The magnet-strain sensors type QE-1008 are latest generation extensometers with two integrated super magnets to measure the bending compensated tie-bar elongation and/or load ( load: if two extensometers are used on one tie bar). The improved design does not only make the sensor shorter, but also increases the absolute accuracy. Therefore all the sensors are interchangeable.
