Faceplate
The TST is a manually operated torque / angle tester that is available in six
force ranges: 0.3, 3, 25, 100 and 200 in-lb. The solid steel base and aluminum
frame is rugged for durability in many different testing environments. The TST,
like all LSI testers, comes standard with an NIST traceable certificate of calibration.
Absolute Zero
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.
 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.
- Custom tooling is used for repeating parts or specific spring "types" or "families."
- 30-second changeovers with no tools from type to type.
- Identical setups each time.
- Enhanced repeatability.
- Pre-machined blanks make tooling inexpensive and standardized.
- Standard angle zeroing built into the fixture, setup within ± 0.1° every time.
- Better data matching between source and user because of standardization of testing and tooling.
 Universal
Tooling
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.
Rapid Changeovers
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 degree.
Limit Lights / Statistical Analysis - Click
for example
Offered as an option, these features specify a range or tolerance in either load
or deflection angle. Then, with the convenient light indicators, you can determine
if the item tested is low, good or high. Print out a full statistical analysis
clearly showing the results.
Digital Control Panel
The TST has a built-in mean, standard deviation, range, statistical summary and
data logger that can store up to 1,800 test points. It also has automatic deflection
compensation, which corrects for torque windup and always displays accurate angle
measurements. RS 232 is standard. Soft keys give the user access to digital calibration,
linearization and features like user programmable force filter, programmable
length offset, user customized print headings, automatic calculation of mean,
standard deviation and range of data. Use the RS 232 port for statistical printout
or talking to a PC. It works great with LSI's SSS, a PC-based “Statistical & Spreadsheet
Interface Software,” which features dynamic data exchange, allowing you
to communicate to spreadsheets like Excel. Measure torque in in-lb, N-mm, gm-mm,
kg-m, in-oz, ft-lb, N-m, kg-mm and kg-cm.
Automatic Spring Rate Calculation
Two-point testing with automatic spring rate calculation. Test it, then print
out with a statistical summary
Three Rotational Stops
For repetitive applications requiring multiple test points on a given spring,
the Torsion Spring Tester comes equipped with three stops that can be preset
to any given test point.
Battery or 115V AC Powered
A self-contained tester with an internal, rechargeable battery pack (approximately
8-10 hours of continuous operation). Includes 115V AC charger.
Loading Capability
The TST 200 comes standard with two cranking ratios, giving the operator flexibility
when testing. Use the 1:1 ratio for light springs or course movements. Choose
the 40:1 micro adjust to fine tune the measurements.
 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. Lower capacity
torque cartridges have an overload-preventing lock
mechanism.
