FLASH 11


LSI revolutionized the spring testing industry again with the FLASH series 1,000 lb testers. Our Whisper Servo drive is a closed loop servo drive that increases rapid travel speed by 200%! Load speeds are now maintained at rapid speed to full load. It operates very quietly at any speed or load. These changes result in faster and quieter testing. Faster test speeds will result in test cycle time reductions of 30% to 400% with the largest time reductions on the heaviest springs.

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.

Fatigue Plate Assembly (Requires Fatigue Test Option)

Fatigue Plate Assembly

Part Number: 025-0000-0449-01

Test the endurance of your part, and keep track of it’s performance throughout the test. With capability of up to 10 million test cycles, you can put your part in and forget about it! And if the part falls below spec, the test automatically stops.

Test up to 8 springs or other parts at a time with Larson’s Fatigue Plate Assembly. Special knobs keep parts in place during testing; choose diameters between 3/4″, 1/2″, and 1/4″.

  • Up to 10 million cycles
  • Abort test on bad condition
  • Performance test at beginning, during, and after fatigue test as desired
  • 10 million cycle option included with Fatigue Assembly or Pro Ultimate Software Package, or as a separate feature.
How do you use the Fatigue Testing Option?
Typical test:
The part must be cycle tested 90,000 cycles from 2.2 to 1.8″. Performance at the end of the cycle test must maintain load ratings.

Air Vibration Damping Feet (Set of 4)

Fatigue Plate Assembly

Part Number: 025-0000-0305-00

Air vibration damping feet make possible very accurate force measurements in normal industrial environments that have floor or building transmitted vibrations. These vibrations may be induced by industrial equipment, local vehicle or rail traffic, and, in some cases, people walking by. The feet attenuates the magnitude of the vibration by 10 to 100 times, making possible accurate force measurements at very light load levels in environments that make testing impossible. The feet should be considered for applications with forces less than 10 lbs. and is highly recommended at less than 2 lbs.

Vibration Damping Table Setup:

  • Mount Air Vibration Damping Feet to bottom of Flash 11 or 24 (Requires 4)
  • Fill with air
