Feature Weighing & ingredients
he ability to maintain consistently high product quality and optimise operating capacity are just some of the reasons why ensuring the accuracy of measuring instrumentation is so important in manufacturing. Indeed, calibration can provide a number of benefits and ensure the safety of both employees and con- sumers alike. However, traditional calibration methods are typically associated with production downtime and high costs. This may mean calibration is priori- tised for some measuring instrumenta- tion at the expense of instruments considered less essential. But the risk of neglecting calibration can lead to even greater costs being incurred. Applied Weighing’s HydraCal direct force calibration system allows for a weighing vessel or silo to be fully cali- brated in a fraction of the time taken using traditional flowmeter or weigh- bridge calibration methods, thereby minimising production downtime and generating significant cost savings.

The technique can be carried out easily on any weigh vessel with suit- able jacking points fitted at each load cell location. There are two methods that can be used; reverse calibration and force calibration.
The reverse calibration method involves the HydraCal system being used to push a known amount of weight off a full or partially full system. Applied Weighing’s engineers jack the system in multiple, measured intervals back to zero, enabling them to check the overall system accuracy, the system linearity and repeatability. This method can often be carried out without the need to modify an existing system as most systems already have a suitable jacking point at each load cell. Reverse calibration is particularly good on bulk storage silos which are rarely emptied, because the calibration method can be carried out with product in the vessel. Alternatively, with the correct brack- ets in place, the force calibration method requires the HydraCal system to apply a measured force down onto a
The HydraCal system is fully traceable, with cer- tification issued as standard, and ATEX approved for use in hazardous areas. Calibration accura- cy is to within 0.1%, offering advantages over alternative calibra- tion methods
weighing vessel, thereby allowing Applied Weighing’s engineers to cali- brate the system in multiple intervals, often up to the full scale of the weigh- ing system.
Both techniques are quick and simple once the calibration system is positioned, consequently limiting the downtime of the vessel and ensuring less production schedule problems.
