Automatic Torsion Spring Tester
The ATST is a motorized torque / angle tester that is available in six load ranges: 3, 25, 100, 200, 500 and 1,300 in-lb. Fast, quiet testing with closed loop servo drives. The solid steel base and aluminum frame is rugged for durability in many different testing environments. The ATST, like all LSI testers, comes standard with an NIST traceable certificate of calibration.
FLASH technology was redesigned from the ground up with full color interactive graphics using a 10.4″ LCD touch screen interface and allows for on-demand statistical and graphical analysis and Larson Systems’ new Quick Test and Quick Launch features. Quick Test automatically finds basic testing points without having to program anything except torque or angle limits. Quick Launch allows multiple operators to efficiently use one tester using fast user switching; no more time wasted saving and loading programs!
Take the guesswork out of testing with LSI’s revolutionary absolute zeroing technique. Used with custom interchangeable tooling, this technique improves repeatability of setups and results during testing. Parts are then measured against the nominal dimensions according to the drawing or specifications, not to a relative point requiring intuition and guesswork.
Custom Interchangeable Tooling
Using LSI’s custom interchangeable tooling technique, you can machine tooling blanks to fit your specific applications or send the information to us and we will do the work for you.
- Achieve 30 second tool-less changeovers from type to type
- Identical setups each time enhance repeatability
- Pre-machined blanks make tooling inexpensive and standardized
- Tooling can be designed to exactly match assembly features for best correlation
- Built-in angle zeroing provides ± 0.1° setup accuracy every time
- The best solution for repeating parts or specific spring types or families

With the universal tooling supplied by LSI, you can test many parts with no special fittings. This is great for unique or one-time job runs with a minimum of setup time.
- 2″, 3″ & 4″ universal fittings
- A conventional approach that has good flexibility in making setups
- Includes chuck, mandrill set to 17/32″ diameter and reaction plate

Both custom and universal tooling is designed to be changed in seconds… YES! In just seconds, you can go from one setup to the next, maintaining your repeatability and reproducibility. Setups within ± 0.1°.
Smart Interchangeable Torque Cartridges
Switch from one torque cartridge to another in just minutes, allowing for a single tester to test a wide range of capacities quickly and accurately. Smart torque cartridges can be digitally calibrated. You can also send in only the smart torque cartridge to LSI for remote calibration (full system calibration is better than individual component calibration).
Delicate lower-capacity torque cartridges feature overload-preventing lockout mechanisms
Crank Z-Axis the control to desired length for specific length compression testing.
Available on our ATST 200, ATST 500 and ATST 1300 standard base units for both high and low profile models.
