Snap-on TTC11 Torque Transducer, 1/2″ Drive, 20-250 ft-lb, for Versatest and TTC Systems

Description

A quality lab that checks 1/2 in click wrenches up to 250 ft-lb needs a sensor sized for that work. The Snap-on TTC11 torque transducer covers that span, 20 to 250 ft-lb, through a 1/2 in square drive. That equals about 27 to 339 N·m. It also carries a memory chip, so a Versatest or TTC2000 monitor knows which sensor is on.

Range floors next to the TTC11

Snap-on quotes the Versatest and TTC2000 systems at ±0.25% of indicated value from 10 to 100% of full scale. So the TTC11 gives its best readings from about 25 ft-lb up. Below that, the TTC10 suits light wrenches better.

Single TTC11 or the 4-in-1 TTC400

The TTC400 also tops out at 250 ft-lb, yet it packs several ranges into one unit. That saves swaps on a bench that tests many small and mid-size wrenches. On the other hand, a lab that runs mostly 1/2 in tools may prefer the dedicated TTC11. In addition, the force kits for tensiometers and gauges work only with single transducers, not the TTC400.

Testers that read the Snap-on TTC11 torque transducer

The VERSA600LDR2 loader works with any TTC sensor from 15 in-oz to 600 ft-lb, so the TTC11 fits the VERSATEST600 bench. Next, the TTC2000 and TTC2800 systems recognize TTC smart transducers automatically. Snap-on also states that every TTC transducer includes the right adaptor for its range.

Mounting and limits for the TTC11

Mount the sensor on its TTC3422 bracket so it cannot twist under load. Then stay within 250 ft-lb, because Snap-on warns against exceeding rated torque. Snap-on also calls for periodic recalibration checks of the tester. For that work, the TTC1520 butterfly wheel and the No. 2 weight set cover this range.

Which calibration wheel matches its top end?

The TTC1520 10 in butterfly wheel, rated to 250 ft-lb. Snap-on says its wheels can calibrate any TTC series transducer.

What is the TTC11 range in N·m?

Snap-on rates it in ft-lb. Converted, 20-250 ft-lb equals about 27-339 N·m.
