Snap-on TTC8 Torque Transducer, 3/8″ Drive, 80-1,000 in-lb, for TTC Test Systems

Description

Plenty of mid-size click wrenches on a factory floor use a 3/8 in drive and work below 100 ft-lb. The Snap-on TTC8 torque transducer checks that band with a 3/8 in drive and a range of 80 to 1,000 in-lb. In other units, that is about 9.0 to 113 N·m, or roughly 6.7 to 83 ft-lb.

TTC8 between its neighbors

So the TTC8 picks up where the TTC7 tops out. It also overlaps the TTC10 from 120 to 1,000 in-lb.

Wrenches that suit the Snap-on TTC8 torque transducer

Snap-on quotes ±0.25% of indicated value from 10 to 100% of full scale for its TTC2000 system. For the TTC8, 10% of full scale is 100 in-lb. Many labs test a wrench at 20, 60 and 100% of its scale. For a QC2I75 body (5 to 75 ft-lb), those points are 180, 540 and 900 in-lb. As a result, all three fall inside the TTC8 range. By contrast, the 3/8 in ControlTech CTECH2FR100A reads up to 100 ft-lb, which is 1,200 in-lb. So its top point needs the TTC10 instead.

Snap-on TTC8 torque transducer or the TTC400 4-in-1?

The TTC400 in the TTC2000SYS and TTC2800SYS kits already has a 3/8 in 80 to 1,000 in-lb section, per the Snap-on UK brochure. So a kit owner may not need a separate TTC8 for routine wrench checks. However, Snap-on notes that force testing works only with single transducers, not the TTC400. In addition, the TTC400 needs the TTC5000-1 adaptor plate on Snap-on loaders, while the TTC8 sits on the TTC3421 bracket.

Monitors, loaders and smart memory

The TTC8 plugs into the same family of TTC2000, TTC2800 and Versatest monitors. Each TTC transducer carries a memory chip that identifies it and keeps its calibration, so the monitor sets up on its own. For loading, the VERSA600LDR2 accepts any TTC transducer from 15 in-oz to 600 ft-lb, which covers this sensor.

Mounting and checking the TTC8

Bolt the TTC3421 bracket to a rigid bench, then mount the TTC8 so it cannot rotate. Never load it past 1,000 in-lb, since Snap-on warns against exceeding rated torque. Also plan periodic recalibration checks, as Snap-on advises for its testers. For that work, Snap-on offers weight sets and the TTC25002 calibration stand kit for TTC transducers.

TTC8 buying questions

What drive and range does the TTC8 have?

A 3/8 in square drive and 80 to 1,000 in-lb, about 9.0 to 113 N·m.

Can the TTC8 check a 100 ft-lb wrench at full scale?

No. Its top is 1,000 in-lb, about 83 ft-lb, so use the TTC10 for that point.

Which bench bracket goes with the TTC8?

Snap-on lists the TTC3421, the same mount it gives the 1/4 in sensors and the TTC7.
