Length Deflection

Length Deflection Compensation

Our testers have built in length deflection compensation. Our pre-programed calculations will measure the load cell compression and correct the length. We do the measuring and the math for you, creating greater accuracy in testing results. 

What is length deflection compensation? 

Spring deflection, also known as spring travel or motion, is the action of a compression spring compressing (being pushed), an extension spring extending (being pulled), or a torsion spring winding (being twisted) when a load is applied or released. This is one characteristic (spring deflection) that is measured by a Larson Systems Spring Tester. 

All force/lengh testing devices, regardless of manufacturer, have additional deflection by the load cell and tester frame which occurs as the spring is loaded. If you buy/use a tester without deflection compensation, measurements might include significant length errors. 

Larson Systems has BUILT-IN Length Deflection Compensation so that the user does not have to calculate and apply length corrections. Most competitors do not have length deflection compensation. 

With a Larson Systems product, forget about calculating load cell and frame deflection when testing, we’ve got you covered.
