The inert base and top fixings with spanner flats allow ease of installation. The strain geometry possesses a plane with good EFI performance defined as perpendicular to the loading axis and the spanner flats. This is particularly useful when a loadcell is used to support mass with its weight acting perpendicular to the measurement axis.<\/p>\n<p>We are happy to design variants of this loadcell to meet your specific requirements. Versions can be manufactured for higher temperature operation. Ranges from 100kg to 250kg can be manufactured for fully compensated operation up to +250\u00b0C. Please consult our engineering department.<\/p>\n<p>Note:<br \/>\nEFI = Extraneous Force Immunity<\/p>\n<p>The 20 and 50kg ranges are manufactured in aluminium; the 100 to 250kg ranges are manufactured in stainless steel. When this loadcell is rationalized, the resistors are housed in a capsule located in the loadcell cable 100mm from the free end. Capsule dimensions are \u00d810mm by 57mm.<\/p>\n<p>Connections<br \/>\nThe loadcell is fitted with 2 metres of PVC insulated 4 core screened cable type 7-1-4C.<br \/>\nExcitation + = Red Signal + = Yellow Screen = Orange<br \/>\nExcitation &#8211; = Blue Signal &#8211; = Green<br \/>\nReverse the signal connections to obtain a positive signal in tension mode. The screen is not connected to the loadcell body.<\/p>\n<table class=\"spec\" border=\"0\">\n<tbody>\n<tr>\n<th>Parameter<\/th>\n<th>50 to 500N<\/th>\n<th>1 to 2.5kN<\/th>\n<th>Unit<\/th>\n<\/tr>\n<tr>\n<td>Non-linearity &#8211; Terminal<\/td>\n<td class=\"centre\">\u00b10.1<\/td>\n<td class=\"centre\">\u00b10.35<\/td>\n<td>% RL<\/td>\n<\/tr>\n<tr>\n<td>Hysteresis<\/td>\n<td class=\"centre\">\u00b10.1<\/td>\n<td class=\"centre\">\u00b10.1<\/td>\n<td>% RL<\/td>\n<\/tr>\n<tr>\n<td>Creep &#8211; 20 minutes<\/td>\n<td class=\"centre\">\u00b10.2<\/td>\n<td class=\"centre\">\u00b10.1<\/td>\n<td>% AL<\/td>\n<\/tr>\n<tr>\n<td>Repeatability<\/td>\n<td class=\"centre\">\u00b10.05<\/td>\n<td class=\"centre\">\u00b10.05<\/td>\n<td>% RL<\/td>\n<\/tr>\n<tr>\n<td>Rated output &#8211; Nominal<\/td>\n<td class=\"centre\">1.2<\/td>\n<td class=\"centre\">1.2<\/td>\n<td>mV\/V<\/td>\n<\/tr>\n<tr>\n<td>Rated output &#8211; Rationalised<\/td>\n<td class=\"centre\">1.0<\/td>\n<td class=\"centre\">1.0<\/td>\n<td>mV\/V<\/td>\n<\/tr>\n<tr>\n<td>Rationalisation tolerance (applies to single direction calibrations)<\/td>\n<td class=\"centre\">\u00b10.5<\/td>\n<td class=\"centre\">\u00b10.5<\/td>\n<td>% RL<\/td>\n<\/tr>\n<tr>\n<td>Zero load output<\/td>\n<td class=\"centre\">\u00b14<\/td>\n<td class=\"centre\">\u00b14<\/td>\n<td>% RL<\/td>\n<\/tr>\n<tr>\n<td>Output symmetry<\/td>\n<td class=\"centre\">2.0<\/td>\n<td class=\"centre\">2.0<\/td>\n<td>% AO<\/td>\n<\/tr>\n<tr>\n<td>Temperature effect on rated output per \u00b0C<\/td>\n<td class=\"centre\">\u00b10.005<\/td>\n<td class=\"centre\">\u00b10.005<\/td>\n<td>% AL<\/td>\n<\/tr>\n<tr>\n<td>Temperature effect on zero load output per \u00b0C<\/td>\n<td class=\"centre\">\u00b10.01<\/td>\n<td class=\"centre\">\u00b10.01<\/td>\n<td>% RL<\/td>\n<\/tr>\n<tr>\n<td>Temperature range &#8211; Compensated<\/td>\n<td class=\"centre\">-10 to +50<\/td>\n<td class=\"centre\">-10 to +50<\/td>\n<td>\u00b0C<\/td>\n<\/tr>\n<tr>\n<td>Temperature range &#8211; Safe<\/td>\n<td class=\"centre\">-10 to +80<\/td>\n<td class=\"centre\">-10 to +80<\/td>\n<td>\u00b0C<\/td>\n<\/tr>\n<tr>\n<td>Excitation voltage &#8211; Recommended<\/td>\n<td class=\"centre\">10<\/td>\n<td class=\"centre\">10<\/td>\n<td>V<\/td>\n<\/tr>\n<tr>\n<td>Excitation voltage &#8211; Maximum<\/td>\n<td class=\"centre\">10<\/td>\n<td class=\"centre\">10<\/td>\n<td>V<\/td>\n<\/tr>\n<tr>\n<td>Bridge resistance<\/td>\n<td class=\"centre\">350<\/td>\n<td class=\"centre\">350<\/td>\n<td>\u03a9<\/td>\n<\/tr>\n<tr>\n<td>Insulation resistance &#8211; Minimum at 50Vdc<\/td>\n<td class=\"centre\">500<\/td>\n<td class=\"centre\">500<\/td>\n<td>M\u03a9<\/td>\n<\/tr>\n<tr>\n<td>Overload &#8211; Safe<\/td>\n<td class=\"centre\">50<\/td>\n<td class=\"centre\">50<\/td>\n<td>% RL<\/td>\n<\/tr>\n<tr>\n<td>Overload &#8211; Ultimate<\/td>\n<td class=\"centre\">200<\/td>\n<td class=\"centre\">200<\/td>\n<td>% RL<\/td>\n<\/tr>\n<tr>\n<td>Sealing<\/td>\n<td class=\"centre\">IP65<\/td>\n<td class=\"centre\">IP65<\/td>\n<td>&nbsp;<\/td>\n<\/tr>\n<tr>\n<td>Weight &#8211; Nominal (excluding cable)<\/td>\n<td class=\"centre\">50<\/td>\n<td class=\"centre\">70<\/td>\n<td>g<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p>Compact axial load cell with improved EFI compared to diaphragm load cells<\/p>\n","protected":false},"featured_media":288831,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[5487],"product_cat":[3377],"product_tag":[5030],"class_list":{"0":"post-288832","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-althen-sensors","7":"product_cat-miniature-load-cell","8":"product_tag-force-sensor-en2","10":"first","11":"instock","12":"taxable","13":"shipping-taxable","14":"product-type-simple"},"acf":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/casscale.net\/en\/wp-json\/wp\/v2\/product\/288832","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/casscale.net\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/casscale.net\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/casscale.net\/en\/wp-json\/wp\/v2\/comments?post=288832"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/casscale.net\/en\/wp-json\/wp\/v2\/media\/288831"}],"wp:attachment":[{"href":"https:\/\/casscale.net\/en\/wp-json\/wp\/v2\/media?parent=288832"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/casscale.net\/en\/wp-json\/wp\/v2\/product_brand?post=288832"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/casscale.net\/en\/wp-json\/wp\/v2\/product_cat?post=288832"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/casscale.net\/en\/wp-json\/wp\/v2\/product_tag?post=288832"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
