Unlike motorized testing machines, which operate at a fixed speed, the MDD allows the operator to control the rate at which force is applied\u2014which can be an advantage for certain tests that require a gradual approach or a reading once the force has stabilized.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">For applications requiring controlled and repeatable travel speeds, automated force-displacement curves, or high test rates, ACRN also offers Mecmesin (MultiTest) motorized test stands, available upon request.<\/p>\n<h3>Advantages of the MDD<\/h3>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li><span style=\"color: #215876;\">Portable and robust<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li><span style=\"color: #215876;\">Crank + screw: stable, sensitive and precise (2mm\/turn)<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li><span style=\"color: #215876;\">High precision with advanced dynamometer up to 1000N<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li><span style=\"color: #215876;\">Multiple options for better accuracy and ergonomics<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<div class='content-column one_half'><h3>Options<\/h3>\n<table style=\"border-collapse: collapse;

It is the ideal solution for quality control laboratories and workshops that need a reliable, portable testing station without having to rely on a motorized test bench.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">The operating principle is based on a precision ball screw driven by an ergonomic crank. Each turn of the crank moves the crossbar 2 mm, allowing for precise and repeatable positioning of the applied force. A self-locking screw mechanism maintains pressure on the sample during the measurement, eliminating the need for the operator to hold the position manually.<\/p>\n<p class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\">The MDD is compatible with all Mecmesin force gauges (BFG, AFG) and can be supplemented with an optical digital scale (resolution 0.01 mm) to simultaneously measure displacement and force\u2014transforming the bench into a true basic force\/displacement tester.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"featured_media":4356,"template":"","meta":{"_acf_changed":false,"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":""},"product_brand":[],"product_cat":[97],"product_tag":[],"class_list":{"0":"post-4399","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-compression-tensile-bench","8":"first","9":"instock","10":"shipping-taxable","11":"purchasable","12":"product-type-simple"},"acf":[],"_links":{"self":[{"href":"https:\/\/www.acrn.fr\/en\/wp-json\/wp\/v2\/product\/4399","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.acrn.fr\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.acrn.fr\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.acrn.fr\/en\/wp-json\/wp\/v2\/media\/4356"}],"wp:attachment":[{"href":"https:\/\/www.acrn.fr\/en\/wp-json\/wp\/v2\/media?parent=4399"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.acrn.fr\/en\/wp-json\/wp\/v2\/product_brand?post=4399"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.acrn.fr\/en\/wp-json\/wp\/v2\/product_cat?post=4399"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.acrn.fr\/en\/wp-json\/wp\/v2\/product_tag?post=4399"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
