The micro-stepper motor drive, high precision ball screw actuator, and electronic compensation for load cell deformation provide very high accuracy and repeatability of the ram position. High precision load cells are mounted on removable dovetail cartridges and provide high load accuracy. The load cell cartridges are pin coded to automatically identify the load range to the display module. The cartridges are easily changeable by the operator. The aluminum platens, which eliminate the effects of residual magnetism, are ground, nickel plated, and inspected for squareness and parallelism. Guide bearings are pre-loaded to eliminate the possibility of back lash.
The accompanying Model 3700 Display Module is used to collect and display spring tester data, as well as control the tester. The system uses LINK’s patented “Pass-Thru” feature provides a fast and accurate means of testing “on the run” with up to 8 load load and/or 8 height setpoints at which the spring is to be tested. As the spring "passes through" each control point, the corresponding data is automatically captured and displayed. Spring rate can be automatically calculated and displayed by selecting any two, non-corresponding set points (height or load. The module is powered with a universal power supply with US plug (standard).
