They provide innovative Instant Reset, Always On, and Laser Alignment features to maximize performance and increase testing throughput.<\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"line-height:normal\">They are suitable for testing high-modulus materials such as metals and composites, high-elongation materials, and thin or delicate specimens, for cyclic fatigue, strain-controlled testing, deflectometer applications, and measuring crack opening displacements. Strain or extension is measured and output in real time.<\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"line-height:normal\">Epsilon One\u2019s high resolution and ISO 0,5 \/ ASTM B-1 accuracy classes make it suitable for noncontact measurement of a wide range of strain values, from very small strains required to measure modulus of metals, composites, ceramics and CMCs, through elastomers and everything in between.<\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"line-height:normal\">Class-leading accuracy and resolution are achieved by Epsilon\u2019s comprehensive optical path optimization, a unification of several optical technologies and signal-processing algorithms. Ultrahigh camera resolution, real-time data rates up to 3000Hz, minimization of optical error sources, and signal processing techniques provide high strain resolution and accuracy with the lowest noise. No other system on the market combines all of these technologies.<\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"line-height:normal\">The Laser-Assist Alignment System provides an instant alignment and distance spot check. Epsilon One will project pre-aligned laser lines on the specimen before the test, revealing any misalignment. During the test, high precision telecentric lenses eliminate errors due to out-of-plane movements \u2013 on low strain materials and components. Epsilon One arrives factory calibrated \u2013 there are no calibration grids or gauge length bars, saving a great deal of time.<\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"line-height:normal\">The system sets up for new specimen types in minutes and requires very little training or skill to use. The desktop user interface software and optional Touch Interface provide continuous digital readouts and status information. Epsilon One was designed for the fastest specimen cycle times. <\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin-bottom:.0001pt\"><span style=\"line-height:normal\"><a href=\"http:\/\/www.tiniusolsen.com\">www.tiniusolsen.com<\/a> <\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Tinius Olsen, Horsham, Pa., offers the Epsilon One high-precision optical non-contact extensometers that perform high-accuracy, high-resolution, non-contacting axial strain and displacement measurements.<\/p>\n","protected":false},"author":63103,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[454,440,441,1],"tags":[],"class_list":["post-11077","post","type-post","status-publish","format-standard","hentry","category-metals-and-alloys","category-news","category-news-articles","category-uncategorized"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.9 -
