Perform one- and two-point testing to calculate spring constant and spring rate. Calculate free length and initial tension results for compression or extension springs. Load measurement accuracies to better than 0.1% are achieved using our IEEE 1451.4 compliant load cell sensors. Capacities range from 1N to 50kN (100 gf to 11,250 lbf). An automatic datuming feature helps to ensure accurate height/ extension/elongation measurements. Heights can be measured to 0.001 inch (0.025 mm). The deflection compensation feature is ideal for compressive testing where mechanical deflection can adversely effect measurement accuracy and repeatability. 495 M a terial T esting / F orce M easurement
