Calibration schedules take into account the accuracy required for a particular sensor and the length of time during which it has previously been able to maintain that degree of accuracy. "It'sfaster, easier, and more accurate than our old paper-based procedures. " | | |
| | | Sensors that are found to be highly stable need not be re-calibrated as often as sensors that tend to drift. The trick is determining which sensors should be re-calibrated after a few hours, weeks, or years of operation and which can be left as-is for longer periods without sacrificing quality or safety. Doing so allows maintenance personnel to concentrate their efforts only where needed, thereby eliminating unnecessary calibration work. The calibration schedule at Croda is determined by three criteria. They must first comply with all governmental and insurance regulations that mandate protection for the plant, its personnel, and its environment. These are Croda's top priorities and in some ways the most expensive, not so much for the direct costs of complying with the mandated calibration operations, but for the potential cost of failing to comply. In the UK, as well as in the EU and the US, government agencies can shut down a plant completely for violating health and safety regulations, including those for calibration. | | |
