Torque DTTIND-407

Digital Torque Transducer w/indicator

The intent of this ILC/PT is to provide a means for participant labs to evaluate the appropriateness and effectiveness of participant practices, training, and measurement uncertainty relating to calibration of a Torque Transducer.

The kit includes two torque transducers and a digital indicator. This ILC/PT refers to testing the smaller transducer. Participants are asked to make 10 measurements of Torque (5 CCW, and 5 CW) from 30 lbf-in to 300 lbf-in. The most common method used for this ILC/PT will consist of tests weights and torque arm.

Participants are expected to be familiar with, and have appropriate lab equipment and measurement uncertainties for calibration of similar devices.

**TRAVEL KIT: This kit travels with the DTTIND-417, should you decide to participate in the DTTIND-417 there is an additional $100 fee per ILC/PT.

Torque DTTIND-417

Digital Torque Transducer w/indicator

The intent of this ILC/PT is to provide a means for the participant to determine the appropriateness and effectiveness of participant practices, training, and measurement uncertainty relating to calibration of a torque transducer.

This kit includes two torque transducers and digital indicator. This ILC/PT includes the larger transducer. Participants are asked to make 10 measurements of Torque (3 CCW and 5 CW) within a range of 180 lbf-in to 1800 lbf-in. The most common method used for this ILC/PT will consist of tests weights and torque arm.

Participants are expected to be familiar with, and have appropriate lab equipment and measurement uncertainties for calibration of similar devices.

Torque TORQ-201

Torque Wrench Set of 3 Wrenches

The intent of this ILC/PT is to provide a means for the participant to determine the appropriateness and effectiveness of participant practices, training, and measurement uncertainty relating to calibration of Torque Wrenches with a reference uncertainty of 2% i.v. on pound*inch range and 1% i.v. on pound*foot range.  

This ILC/PT Kit contains three Torque Wrenches, covering ranges 30 in*lb to 540 in*lb and 20 ft*lb to 90 ft*lb. Participants are asked to use their lab practices to make measurements of Torque at nine set points (three set points per wrench). Measurement values will be appropriate for calibration of similar devices.

Participants are expected to be familiar with, and have appropriate lab equipment and measurement uncertainties for calibration of similar devices.

Torque TORQ-301

Torque Transducer

This program is offered to laboratories simulating torque measurements with transducers or the combination of weights and arms.

Participants measure torque in the clockwise (CW) and counter-clockwise (CCW) direction from 200 lbf*in to 2000 lbf*in. The results are provided in mV/V with the reported uncertainty. The associated uncertainty for this program is in the range of 0.002 mV/V to 0.004 mV/V.

Participants are expected to be familiar with, and have appropriate lab equipment and measurement uncertainties for calibration of similar devices.

Torque TORQ-514

Torque Wrench Set of 4 Wrenches

The intent of this ILC/PT is to provide a means for participant laboratories to evaluate the appropriateness and effectiveness of the their practices, training, and measurement uncertainties relating to the measurement of Torque by comparison of reported data and uncertainties to the data and uncertainties of other laboratories measuring the same data points on the same artifacts.

This ILC/PT Kit contains 4 Torque Wrenches: two Digital 1800 in*lb and 2 Flat Beam 600 in*lb Wrenches.

Participants are asked to use their lab practices to make Torque measurements at three Set Points per wrench for a total of 12 Set Points in the range of 100 to 1800 in*lb. Measurement values will be appropriate for calibration of similar devices. 

Participants are expected to be familiar with, and have appropriate lab equipment and measurement uncertainties for calibration of similar devices.
