FLASH 25

The FLASH 25 has been redesigned from the ground up alongside its big brother, the FLASH 48. It features our four ball screw design for stability, 12″ diameter platforms, a 24″ stroke, our Whisper Servo Drive for fast, quiet testing and the FLASH touch screen interface. The FLASH 25 also has a bevy of optional features: a light curtain (the two yellow bars in the photo) for additional safety when testing Belleville washers or wave springs; a center length transducer for increased accuracy when testing small parts with high spring rates; a pneumatic thru-rod assembly for parts that tend to buckle under load, and Quick Change Load Cell capability.

Center Length Transducer
The Center Length Transducer is an optional secondary encoder used on the FLASH 25 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/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.
