APPLIED WEIGHING’S CALIBRATION INNOVATION

Whilst traditional calibration methods are usually associated with production downtime and high costs, Applied Weighing’s HydraCal direct force calibration system allows for a weighing vessel or silo to be fully calibrated in the fraction of the time taken using flowmeter or weighbridge calibration methods. The spectre of production downtime arising from calibration can lead some manufacturers to delay the procedure. Others prioritise their equipment; exposing neglected instrumentation to unwanted deviations. But by minimising production downtime and generating significant cost savings, the HydraCal system presents a real solution to the concerns associated with calibrating measuring instrumentation. Given the significance of the ability to maintain consistently high product quality and optimise operating capacity, ensuring the accuracy of measuring instrumentation is afforded great importance within the manufacturing industry. Both a proven and revolutionary technique, the HydraCal system can be carried out easily on any weigh vessel with suitable jacking points fitted at each load cell location. There are two methods that can be used depending on the suitability and type of the vessel; 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 brackets in place, the force calibration method requires the HydraCal system to apply a measured force down onto a weighing vessel, thereby allowing Applied Weighing’s engineers to calibrate the system in multiple intervals, often up to the full scale of the weighing 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. Calibration accuracy is to within 0.1%, signalling the technical superiority that Applied Weighing’s HydraCal system has over alternative calibration methods. The system is also fully traceable, with certification issued as standard, and ATEX approved for use in hazardous areas. First established in 1990, Applied Weighing provides a complete range of weighing solutions and systems. These are custom built to meet individual customer requirements. Their range includes platform scales, silo and vessel weighing systems, drum filling systems, high speed weighing systems, telemetry systems and load cells. Applied Weighing products are used in a diverse variety of industry areas including pharmaceutical, food processing, milling and bakeries, aggregates and cement, fuel oils, chemicals and plastics. Their aim is to provide quality products on short delivery times, backed up with comprehensive technical support. Applied Weighing is an ISO 9001:2015 registered company and is certified for the manufacture of ATEX compliant products.
