FLASH 48
The FLASH 48 is a fully featured upgrade of our FLASH 25 tester with a 48-inch stroke designed to accommodate large parts with heavy loads. It features our four ball screw design for stability with a triple load cell lower platform to prevent off-center loading problems. With a fully enclosed assembly for maximum safety, this tester has a standard platform diameter of 12” and is even capable of being outfitted with any of our Quick Change Load Cells, giving the FLASH 48 an extremely versatile load capacity range from 2 lbf to 15,000 lbf.
Optional Features:
The FLASH 48 was designed from the ground up to be compatible with a variety of other optional features, like a light curtain guard for additional safety, a thru rod support assembly or a center length transducer for very accurate testing of small deflection, high-rate parts, like Belleville washers or wave springs.
Center Length Transducer
The Center Length Transducer is an optional secondary encoder used on the FLASH 48 to test small deflection, high-rate springs, like Belleville Washers or wave springs. When activated, the tester will switch over to this encoder to measure length for parts that are shorter than 0.850 inches, giving extremely accurate readings for small parts with high spring rates.

Includes Length Deflection Compensation
What is length deflection compensation?
All force/length 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.
