Control accuracy is increased by servo motor and driver; the test can be carried out in a wide range of speed with high accuracy (0.001-1000mm\/min) via feedback from the encoder. Load frame is designed so that various grips can be mounted in order to carry out different tests. Precision load cell attached to the grip can directly sense any change in force. Low profile load cell, capacity 2000Kgf is used to carry out class 0.5 compression tests, i.e. max error 0.5% of reading in a range of 2%-100% of the load cell capacity as per EN 10002, and ISO 7500 standards (SANTAM calibration certificate is attached), resolution 1\/100000; this minimizes the machine error, leading to increase in force measurement accuracy during the test. From the other side, various tools and accessories with SANTAM software (STM controller and advanced JADOO) provide the capability of carrying out the spring tests. Precision displacement control with feedback from encoder with high resolution (0.001mm), accuracy 0.05mm stabilizes the test velocity. Wide range of grip velocity enables the operator to carry out pertinent tests in different fields. To carry out the compression tests on spring, the machine automatically calculates the initial length as well as the decrease in length of the spring to obtain K curve as per the common definition; the machine can be calibrated according to the compression and tensile grips stiffness as well. Different extensometers with high resolution are other auxiliary tool used to measure strain from the specimen (instead of jack). For this purpose, the machine can use SANTAM powerful software (STM controller, and JADOO). In case of using JADOO, the machine can either read the displacement by means of the extensometer attached to the specimen or use the extensometer to receive feedback for closed loop control, and control the precision loading rate. Another advantage is easy installation of different fixtures and specialized grips by means of pin fasteners with self-aligning capability.<\/p>\n","protected":false},"excerpt":{"rendered":"<ul>\n<li dir=\"ltr\" style=\"text-align: left;\">Designed based on the tests carried out on springs<\/li>\n<li dir=\"ltr\" style=\"text-align: left;\">Servo electrical operating mechanism with ball screw (double columns)<\/li>\n<li dir=\"ltr\" style=\"text-align: left;\">Capable of testing types of springs with respect to the machine capacity<\/li>\n<li dir=\"ltr\" style=\"text-align: left;\">Equipped with precision compression grip with surface parallelism<\/li>\n<li dir=\"ltr\" style=\"text-align: left;\">Low profile load cell, class 0.5, capacity 2000Kgf<\/li>\n<li dir=\"ltr\" style=\"text-align: left;\">Displacement sensor to measure the cross head displacement<\/li>\n<li dir=\"ltr\" style=\"text-align: left;\">AC servo motor and driver with closed loop control<\/li>\n<li dir=\"ltr\" style=\"text-align: left;\">Fully computerized control via port serial RS-232 and USB by means of DSP technology with no restriction in PC type<\/li>\n<li dir=\"ltr\" style=\"text-align: left;\">A powerful software compatible with Windows OS to carry out test complete with full test report and applying various constant rates of loading and displacement (such as force rate, stress rate, strain and displacement rates)<\/li>\n<li dir=\"ltr\" style=\"text-align: left;\">Low profile load cells can be easily mounted to increase the measurement accuracy<\/li>\n<li dir=\"ltr\" style=\"text-align: left;\">Various fixtures and specialized grips can be easily installed by pin fasteners<\/li>\n<li dir=\"ltr\" style=\"text-align: left;\">High repeatability of results<\/li>\n<li dir=\"ltr\" style=\"text-align: left;\">Ease of operation, mountable on table<\/li>\n<\/ul>\n","protected":false},"featured_media":41985,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_cat":[275,565],"product_tag":[],"class_list":["post-30180","product","type-product","status-publish","has-post-thumbnail","product_cat------2--en","product_cat-spring-testing","first","instock","shipping-taxable","product-type-simple"],"gallery_images":[59213,59210,59207,59204,59201,59198,59195,59177],"_links":{"self":[{"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/product\/30180","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=30180"}],"version-history":[{"count":7,"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/product\/30180\/revisions"}],"predecessor-version":[{"id":33333,"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/product\/30180\/revisions\/33333"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/media\/41985"}],"wp:attachment":[{"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/media?parent=30180"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/product_cat?post=30180"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.santamco.ir\/en\/wp-json\/wp\/v2\/product_tag?post=30180"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
