MSM31 DEMEC Mechanical Strain Gauge Features Analog / Digital Indicator Suitable for wide Strain Ranges Calibrated to Measure based on Micro-Strain (200 measurements per hour) Option of Connection to Data Processor Easy to Use, De-mountable and Re-usable Description The DEMEC Mechanical Strain Gauge developed as a reliable and accurate way of taking strain measurements at different points on a structure using a single instrument. Standard gauge lengths are from 100mm to 500mm, while length of up to 2000mm available on request. The DEMEC strain gauge is ideal for use on many types of structure for strain measurement and crack monitoring. The digital DEMEC strain gauge incorporates a digital indicator with a resolution of 0.001mm, zero set, pre-set and output for Statistical Process Control (SPC) systems. The indicator can be connected to a data processor for recording and analysis of results. The indicator displays spindle movement digitally by means of a linear encoder and has a response speed of 1000mm/sec, and is battery operated. Applications Crack monitoring Strain Measurement of Structures in: Civil Engineering Mining Research Technical Specifications The DEMEC strain gauge consists of an invar main beam with two conical locating points, one fixed and the other pivoting on a special accurate knife edge. The points locate in pre-drilled stainless steel discs which are attached to the structure with adhesive. Movement of the pivoting point is measured by the strain gauge which is attached to a base plate on the invar beam. Design is such that thermal movement within the instrument is negligible.
