It features an accurate torquemeter (with an accuracy better than 1% of reading in the range of 2-100% of the machine capacity) and an accurate angle measurement transducer (resolution: 0.001\u00b0)<br \/>\nTorsion test can be performed with maximum speed of 30 RPM (3.14 rad\/sec or 10800 degree\/min) and minimum speed of 0.01 RPM (0.001 rad\/sec or 3.6 degree\/min) during torsion in one direction or twisting with specified turns (10 turns clockwise and 10 turns counterclockwise automatically)<br \/>\nIt is fully computerized system connected to a PC via an RS-232 serial port using Digital Signal Processing (DSP) software technology.<br \/>\nThe user-friendly software plots torque versus angle of twist curves and generates comprehensive reports, including data for stress shear (\u03c4), shear strain (\u03b3), shear modulus, yield shear strength, torsional toughness, test speed, specimen dimensions, graph analysis. Furthermore, the software identifies key structural points directly on the graph, such as the ultimate torque, fracture torque, yield point torque, and angle of twist at fracture.<br \/>\nAn optical safety curtain equipped with laser sensors automatically stops machine operation if any foreign object, including operator\u2019s hand or arm, enters the testing zone, or if the special key is left in the machine\u2019s three-jaw chuck.<br \/>\nFor enhanced user-friendliness, the machine is equipped with an independent control keyboard featuring JOG buttons for controlling grip rotation and positioning the specimen.<br \/>\nAdditionally, the machine is supplied with accessories for torsional torque calibration, allowing the customer to perform routine and periodic performance calibrations, complete with an instruction manual.<\/p>\n","protected":false},"excerpt":{"rendered":"<p dir=\"ltr\">&#8211; Maximum torque capacity: 300 N.m<br \/>\n&#8211; Designed in accordance with ASTM B502, ASTM E143, ASTM A938, ASTM B415, ISO 7800<br \/>\n&#8211; Servo-electromechanical operating mechanism<br \/>\n&#8211; Capable of performing fully controlled torsion tests, cyclic loading tests, and hysteresis testing<br \/>\n&#8211; Fully computerized control system with adjustable torsional speed using AC servo motor and servo drive<br \/>\n&#8211; Advanced software for plotting torque-twist angle diagram, performing graph analysis, and comparing multiple test curves<br \/>\n&#8211; Equipped with three-chuck grips featuring manual and hydraulic clamping mechanisms for secure gripping of specimens with different sizes and hardness levels<br \/>\n&#8211; Equipped with a torque transducer for accurate torque measurement (accuracy: 1% of reading)<br \/>\n&#8211; Equipped with an angle displacement measurement system with a resolution of 0.001\u00b0<br \/>\n&#8211; Automatic stop system upon specimen fracture<br \/>\n&#8211; Moveable grips mounted on low-friction bearings<br \/>\n&#8211; Dedicated mechanism for applying axial load to the specimen<br \/>\n&#8211; Supplied with accessories required for torque transducer calibration<br \/>\n&#8211; Includes a portable control keypad<\/p>\n","protected":false},"featured_media":49544,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_cat":[260],"product_tag":[],"class_list":["post-30164","product","type-product","status-publish","has-post-thumbnail","product_cat-300---en","first","instock","shipping-taxable","product-type-simple"],"gallery_images":[49536,49539,49533,49542],"_links":{"self":[{"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/product\/30164","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/comments?post=30164"}],"version-history":[{"count":13,"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/product\/30164\/revisions"}],"predecessor-version":[{"id":61095,"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/product\/30164\/revisions\/61095"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/media\/49544"}],"wp:attachment":[{"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/media?parent=30164"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/product_cat?post=30164"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/product_tag?post=30164"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
