Torque Controller - AMT

A torque controller is a device used to regulate and monitor the amount of torque being applied by a torque tool (such as a nutrunner or torque wrench). It ensures that the fastener is tightened to the desired torque setting, typically based on manufacturer specifications or quality standards. The controller may feature settings for different torque ranges, visual or auditory indicators to alert the operator when the target torque has been reached, and safety features to prevent over-tightening. It plays a crucial role in ensuring the accuracy, consistency, and safety of bolting operations.

The working principle of a torque wrench is based on a mechanical or electronic system that measures the amount of rotational force (torque) applied to a fastener. When the torque wrench is used to tighten a bolt or nut, the internal mechanism (such as a spring, dial, or electronic sensor) detects the amount of force being applied. Once the preset torque value is reached, the wrench either clicks (in the case of a mechanical torque wrench) or displays an alert (in the case of a digital wrench), signaling to the operator that the desired torque has been achieved. This helps ensure that the fastener is tightened correctly without being over or under-tightened.

The function of a torque tool is to apply a specific amount of torque to a fastener, such as a bolt or nut, ensuring it is tightened to the correct specification. Torque tools are essential for ensuring the structural integrity and safety of bolted joints in various industries, including automotive, construction, aerospace, and manufacturing. They are used to prevent damage to fasteners and components, avoid over-tightening (which can cause material damage or deformation), and ensure that the correct tension is applied for proper joint performance. Torque tools can be manual (like a torque wrench) or powered (like an electric or pneumatic nutrunner).
