What Equipment is used for Torque Wrench Calibration?

Calibrating torque wrenches plays a role in ensuring the accuracy and reliability of torque applications across industries like mining, automotive, aerospace and manufacturing. The precision of these tools directly impacts the quality and safety of products. To uphold standards, specific equipment is used for torque wrench calibration. Here we highlight the tools involved in the calibration process and explains their functions and significance.


What is Torque Wrench Calibration?


Torque wrench calibration involves verifying and adjusting the torque tools output to guarantee it applies the correct torque when used on fasteners or bolts. Regular calibration is essential to meet quality control standards and prevent equipment failures or product defects resulting from torque application. The process includes comparing the torque wrenchs readings with a known standard and making adjustments to ensure alignment.


What are Torque Calibrators?


At the core of torque wrench calibration equipment are torque calibrators. These devices serve as high precision standards for testing and calibrating torque wrenches. Torque calibrators come in different types, such as bench top models and portable units catering to individual calibration requirements. They typically feature a display for easy measurement reading. They can handle a broad range of torque values to accommodate different types of torque wrenches. Advanced models come with features such, as data logging, which helps in keeping records of calibration for quality assurance purposes.


What are Calibration Benches?


Calibration benches are workstations designed to make the calibration of torque wrenches and other torque tools more efficient. These benches often include a torque calibrator as part of their setup along with fixtures and adapters to hold different types of torque wrenches during calibration. The design of a calibration bench allows for alignment and stabilisation of the torque wrench ensuring accurate and consistent calibration results. Some benches also have computer interfaces that allow transfer of calibration data for record keeping and analysis.






Torque Testers


Torque testers play a role in the calibration testing of torque wrenches. They help identify any discrepancies in torque output before the formal calibration process begins. While similar to torque calibrators, these devices are specifically designed for testing and verification rather than precise calibration. Torque testers are particularly useful in environments where torque tools are used frequently and need checks to ensure accuracy, between formal calibration intervals.


Load Cells


Load cells are components used in torque calibration equipment to measure force or load accurately. In the context of torque wrench calibration load cells convert the applied torque into a signal that can be measured and displayed. These sensors are well known for their accuracy and dependability playing a role in the calibration process. It is essential to select load cells with precision to match the torque wrenches required range and sensitivity during calibration.


Joint Simulators


Joint simulators, also known as torque simulators replicate the real world conditions in which torque wrenches are used. These devices imitate the stiffness of bolted joints offering a reflection of how the wrench performs in practical applications. Joint simulators are especially vital for calibrating torque wrenches used in scenarios where precise and consistent fastener torque's necessary.


What does Calibration Software do?


Modern calibration processes for torque wrenches often incorporate software for managing and documenting calibration data. This software helps automate calibration procedures ensuring uniformity and accuracy in data collection. Additionally it can send reminders for recalibration schedules and generate calibration certificates and maintain a history of each torque wrenchs calibration records. The use of software enhances efficiency and traceability in the calibration process.




Calibrating torque wrenches is a process that demands specialised equipment to guarantee the tools precision and dependability. Different equipment, like torque calibrators, calibration benches, load cells and joint simulators all have roles in the calibration process. They work together to make sure that torque wrenches function within their specified tolerance limits, which is crucial for ensuring the accuracy of tasks carried out with these tools. By having a grasp of the equipment involved in calibrating torque wrenches industries can gain an understanding of why regular and accurate calibration is vital, for upholding quality and safety standards.
