Torque-Angle-Tension Testing of Threaded Fastener Components

Three-In-One System: Test, Analyze, Certify

The LabMaster Portable (Model 3210, 083210-01000) is an advanced, multi-purpose system designed to test threaded fasteners, analyze bolted joints, and certify power tools. The system is comprised of two components: the LabMaster Portable module that contains data acquisition and a laptop or desktop PC running the LabMaster testing software. The module and computer interface using a USB port.

Simple Test Setup

The LabMaster testing software provides a user-friendly graphic interface. Quickly make changes to existing test setups, easily select different tools and transducers, and view results of previous tests. An easily accessed transducer parameter and test setup directory further simplifies testing setup.

Easy Operation

Once the test is set up, the LabMaster Portable module conducts all of the data acquisition operations. The recorded data are then displayed and managed on the computer for access to network printers, archiving, and communications.

Multiple Inputs

Four analog inputs are available on the LabMaster Portable module to accept data signals from the following:

• Rotary Torque Only and Torque-Angle Transducers
• Tension and Torque-Tension Load Cells
• Hand Torque Wrenches
• Force Washers
• Any 10 Volt Analog Device

High Speed Sampling

The LabMaster Portable includes a data acquisition card which provides high-speed sampling of up to 4000 Hz (software selectable). Sampling can be done on a time or angle basis.

Comprehensive Data

A LabMaster Portable system with a torque-tension research head and a torque-angle sensor can measure and calculate the following:

• Input torque
• Clamp force
• Thread friction torque
• Underhead friction torque
• Angle of fastener rotation
• Torque tension coefficient (T = KDF)
• Thread friction coefficient
• Underhead friction coefficient

Statistical Calculations

The LabMaster Portable offers a variety of statistical reports in numeric and graphic form. Statistical plot of ±3 sigma provides insightful data summaries.

Real-Time Display

The LabMaster Portable and the LabMaster testing software provide real-time display during the test. A user-selectable automatic “Data Save” feature for both numeric and graphic data speeds technician testing time.

Variety of Plots

After the test is completed, rundown data and plots may be viewed on the computer display, printed as hard copy, and/or saved for later data analysis. Numerous configurable plots can be generated.

Thorough Joint Analysis

A joint analysis system will typically include a rotary torque-angle transducer, a thread torque-tension research head, and a printer for numeric and graphic data reports, all of which are available from RS Technologies.
