Its various end fixing options are all inert and easily modified for direct inclusion in mechanical assemblies.<\/p>\n<p>The basic versions of the ALF257 are all sealed to IP65. If better sealing is required IP67 is available as an option. An SY014 integral 4 to 20mA output amplifier can be fitted as an option.<\/p>\n<p>We are happy to design variants of this loadcell to meet your specific requirements.<br \/>\nVersions can be manufactured for operation up to +250\u00b0C. Please consult our engineering department.<\/p>\n<p>Geometry: Beam and diaphragm combination. Tension, compression and bi-directional options are available. All standard bi-directional loadcells are calibrated in both modes.<\/p>\n<p>All standard ranges are manufactured in stainless steel.<\/p>\n<p>Notes<br \/>\n1. AL = Applied load. 3. Temperature coefficients apply over the compensated range.<br \/>\n2. RL = Rated load.<\/p>\n<p>Connections<br \/>\nThe loadcell is fitted with 2 metres of PVC insulated 4 core screened cable type 16-2-4C.<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<h6 id=\"technical-specifications-title\">Technical Specifications<\/h6>\n<div class=\"rounded border border-gray-line\/20 overflow-hidden\">\n<table class=\"!my-0\">\n<thead class=\"sr-only\">\n<tr>\n<th>Specification<\/th>\n<th>Value<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<th class=\"align-top\">Bridge resistance<\/th>\n<td>700 \u03a9<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Creep &#8211; 20 minutes<\/th>\n<td>\u00b10.05% AL<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Excitation voltage &#8211; maximum<\/th>\n<td>20V<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Excitation voltage &#8211; recommended<\/th>\n<td>10V<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Hysteresis<\/th>\n<td>\u00b10.1% RL<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Inclined load error &#8211; concentric at 3\u00b0<\/th>\n<td>\u00b10.25% RL<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Insulation resistance &#8211; minimum at 50vdc<\/th>\n<td>500M\u03a9<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Load direction<\/th>\n<td>Tension, compression, bi-directional<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Measurement range<\/th>\n<td>80kN, 120kN, 160kN, 240kN<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Non-linearity &#8211; terminal<\/th>\n<td>\u00b10.1% RL<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Overload &#8211; safe<\/th>\n<td>50% RL<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Overload &#8211; ultimate<\/th>\n<td>100% RL<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Rated output &#8211; rationalised (applies to single direction calibrations)<\/th>\n<td>2.0mV\/V<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Rationalisation tolerance<\/th>\n<td>\u00b10.1% RL<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Repeatability<\/th>\n<td>\u00b10.02% RL<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Sealing &#8211; r option<\/th>\n<td>IP65<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Sealing &#8211; s option<\/th>\n<td>IP67<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Temperature effect on rated output per \u00b0c<\/th>\n<td>\u00b10.002% AL<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Temperature effect on zero load output per \u00b0c<\/th>\n<td>\u00b10.005% RL<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Temperature range &#8211; compensated<\/th>\n<td>-10 to +50\u00b0C<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Temperature range &#8211; safe<\/th>\n<td>-10 to +80\u00b0C<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Weight &#8211; nominal (excluding cable)<\/th>\n<td>5.5 to 6.5kg<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Zero load output<\/th>\n<td>\u00b14% RL<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Axial compensated loadcell<\/p>\n","protected":false},"featured_media":289012,"comment_status":"open","ping_status":"closed","template":"","meta":{"_acf_changed":false},"product_brand":[5487],"product_cat":[3448],"product_tag":[5030],"class_list":{"0":"post-289013","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-althen-sensors","7":"product_cat-force-sensor","8":"product_tag-force-sensor-en2","10":"first","11":"instock","12":"taxable","13":"shipping-taxable","14":"product-type-simple"},"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.4 (Yoast SEO v27.4) -
