The distance between the grips allows specimens with an effective gauge length of 70 mm to be securely mounted for testing.<br \/>\nFor enhanced user-friendliness, the machine is equipped with an independent control keypad featuring JOG buttons for controlling grip rotation and positioning the specimen. Additionally, an axial force up to 5 kgf can be applied to the specimen using a dead-weight loading system with a pulley mechanism.<\/p>\n","protected":false},"excerpt":{"rendered":"<ul dir=\"ltr\">\n<li>Capable of performing torsion and twist tests on wires and other suitable materials<\/li>\n<li>Designed in accordance with ASTM B498, ASTM B415, ASTM B502<\/li>\n<li>Electromechanical operating mechanism comprising a gearbox, AC servo motor, and servo drive<\/li>\n<li>Equipped with a digital RPM counter with a resolution of 0.1 RPM<\/li>\n<li>Capable of performing torsion and twist cycles, including reverse-twist and wrap tests<\/li>\n<li>Equipped with an axial tensile loading mechanism using dead weights<\/li>\n<li>Equipped with specialized grips for secure clamping of high-strength wires<\/li>\n<li>Equipped with a dedicated controller for twist-speed adjustment and selection<\/li>\n<li>Includes an accurate turn-counting system for monitoring the number of twists until specimen fracture<\/li>\n<li>Automatic stop mechanism upon specimen fracture<\/li>\n<li>Safe and user-friendly operation<\/li>\n<\/ul>\n","protected":false},"featured_media":49713,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_cat":[263],"product_tag":[],"class_list":["post-30167","product","type-product","status-publish","has-post-thumbnail","product_cat-25---en","first","instock","shipping-taxable","product-type-simple"],"gallery_images":[49714,49711,49708,49705,49702,49699,49696],"_links":{"self":[{"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/product\/30167","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=30167"}],"version-history":[{"count":13,"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/product\/30167\/revisions"}],"predecessor-version":[{"id":61088,"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/product\/30167\/revisions\/61088"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/media\/49713"}],"wp:attachment":[{"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/media?parent=30167"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/product_cat?post=30167"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/product_tag?post=30167"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
