Calibration is a vital step in ensuring tools are working as they should be, giving correct readings, providing a safe working environment for end-users, and ensuring that companies are upholding their legal obligations. However, calibration is often confused with accuracy and precision. Here we explore what exactly is meant by calibration and why it’s so important.

What is calibration?

Your tool is working fine, but how do you know it is measuring accurately? That’s where calibration comes in.

Calibration is determining and documenting the difference in readings given by a tool compared with reading a given by a measuring standard (fixed device that is known to be accurate). It is generally followed by the adjustment of the tool. 

The process checks whether the values are within

Mining and earth moving operations can be the ultimate test to your ability to ensure bolted joints stay tight. Constant vibration associated with moving equipment over rough terrain can cause even the nuts to loosen and cause damage or possible injury. 

Air-powered and battery-operated torquing tools make it easy to spot check these connections to insure they are still tight. They can also allow for the regular maintenance check on bolts that have a history of loosening. These hand-held tools are convenient and cost effective. 

Torquing is a critical step in your installation of flanges and equipment, but, it is just so time consuming. You could have flanges with 16 or 60 bolts or turbines with nearly 100. Take the sheer number of bolts times the time it takes to turn them with a hydraulic wrench times the number of passes you have to make to get each flange done. Wow, that’s a lot of minutes. There are a few options to help you speed up this operation and reduce your time to something reasonable. 

Make sure your hydraulic pumps have multiple outlets. Pumps that operate up to 4 tools at once are readily available for rent or purchase. This is good for smaller tools and the time you’re saving is the moving of tools for each bolt. 

Air powered nut runners are a calibrated option to get bolts tightened quickly to
