The Coil Spring Tester is a low cost alternative for measuring high capacity springs. Test parts up to 1,500 lbf and get accurate force and length readings from this sturdy two-post frame. The CST has two-line LED display for easy viewing of its force and length measurements. Length can be measured in inches or millimeters and force can be measured in pounds, kilograms, or Newtons. The CST measures flexible items in compression only. Although low in cost, the Coil Spring Tester features a high degree of built-in precision and accuracy to assure excellent repeatability and reproducibility.
All of Larson Systems’ manually operated spring testers have built-in load cell and frame deflection compensation. This deflection compensation, along with integrated force and length measurements, means the length reads accurately, as displayed, at any force.
The Coil Spring Tester is made with a rugged two-post steel frame and equipped with a precision load cell for force, a glass scale for length and our proprietary precision electronics for analysis and display of exact measurements.
What is length deflection compensation?
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.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.
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.
