Torque testers are essential devices in various industries, providing critical measurements of torsional moments, or the turning and twisting forces, that act on objects during rotation. These machines are vital in ensuring the safety, reliability, and performance of numerous products, ranging from electronics to consumer goods. This article delves into the functionalities, types, and applications of torque tester machines, highlighting their importance in quality control and research and development.
What is a Torque Tester?
A torque tester is a device designed to measure the torque applied to an object, such as screws, bottle caps, or rotary switches. These measurements are crucial in determining the opening and closing forces, turning forces, and sliding resistance of various components. Torque is typically measured in units such as Newton-meters (N-m), Newton-centimeters (N-cm), kilogram-force meters (kgf-m), kilogram-force centimeters (kgf-cm), pound-force inches (lbf-in), or ounce-force inches (ozf-in).
Types of Torque Testers
There are three main types of torque testers: desktop, handheld, and built-in.
- Desktop Torque Testers: These are ideal for measuring the opening and closing torque of container lids, such as those on PET bottles and jars. The sample is fixed to a table, and the measurement is performed manually. With various attachments, these testers can accommodate samples of different sizes and shapes, making them versatile for different applications.
- Handheld Torque Testers: These portable devices are used to measure the tightening and loosening forces of screws and bolts, as well as the operating forces of rotary switches. Handheld testers can be taken directly to the sample location, making them convenient for on-site measurements. They are also suitable for testing finished products.
- Built-in Torque Testers: These are integrated into production lines for continuous torque measurement. They are ideal for environments with limited space due to their small sensor size and can be incorporated into torque control systems for real-time monitoring and quality assurance.
Selecting the Right Torque Tester
When selecting a torque tester, consider the following factors:
- Measurement Environment: Determine whether the sample will be brought to the tester (desktop type) or if the tester needs to be taken to the sample (handheld type). For integrated measurements within a production line, a built-in type is ideal.
- Maximum Torque Value: Choose a torque tester with a range that exceeds the expected maximum torque value to prevent damage to the device.
- Special Functions: High-performance torque testers offer additional features such as angle input/output and two-step peak acquisition, which enhance the precision and versatility of measurements.

How to Measure Torque
Handheld Measurement: Handheld torque measurement involves manually turning the sample fixed to the tester or holding the sensor and turning the sample attached to it. Handheld testers are designed for ease of use and stable measurements. They are particularly useful for imitating human motion, such as opening a lid, where the force applied is not constant but adjusted unconsciously based on the resistance encountered.
Desktop Measurement: Desktop torque testers provide easy and stable sample fixation, allowing for efficient and repeatable measurements. These testers are equipped with double bearing support mechanisms to minimize the effects of lateral and bending forces, ensuring precise measurements.
Attaching Samples and Accessories
Torque testers can be equipped with various attachments to accommodate different sample shapes and sizes. Proper attachment selection is crucial to apply the appropriate force accurately. For instance, the DTXS/DTXA series and HTGS/HTGA series torque testers have specific methods for mounting attachments, ensuring efficient and secure sample fixation.
Enhancing Precision with Torque Stands
Combining a torque tester with a torque stand enhances measurement precision. The method of attaching the tester to the stand varies by model but typically involves securing the tester with screws or using a centering jig for accurate alignment. Torque stands provide stability and repeatability, essential for high-precision measurements.
Visualizing Data with Torque Graphs
Graphing torque measurement data allows for visual analysis of torque values over time. This visualization helps in identifying abnormal torque values and understanding the physical characteristics of the sample. Advanced software options are available to create detailed graphs, overlay multiple datasets, and generate reports in various formats, aiding in comprehensive result evaluation and documentation.
Conclusion:
Torque testers are indispensable tools in numerous industries, supporting both quality control and research and development. By providing accurate measurements of torsional forces, these devices ensure the reliability and performance of products ranging from electronics to consumer goods. Understanding the different types of torque testers and their applications helps in selecting the right tool for specific measurement needs, ultimately enhancing product quality and safety.
