Always attentive to improve existing products as well, Minebea Intec evolves in the checkweighers sector: thanks to the new load cell with electromagnetic force compensation, high speed meets precision
The new WZED load cell with electromagnetic force compensation from Minebea Intec, allows its checkweigher models to take another step further. The new load cell with digital controller have received MID approval (Measuring Instruments Directive) in the legal-for-trade range for belt speeds of up to 3 metres per second – this means up to 600 pieces per minute. The upgrade package contains many more features that pay off for user of high-speed applications. As a specialist in weighing and inspection solutions, Minebea Intec is continuously working to improve existing products as well. With its upgrade to the new generation load cell, the company has put together a complete package of features that in the future will be included in all verifiable checkweigher models which use a high-precision load cell with electro magnetic force compensation.
Products from 5 grams can be verified
The upgrade consists of three elements: The new WZED load cell with electromagnetic force compensation and integrated high-speed electronics with digital controller. The advantages for the customer are therefore many and varied. For example, the new weighing sensor in combination with the digital controller offers increased reliability and precision. In addition, the sensor allows for an extremely low minimum weight: products from 5 grams can be verified according to all standards. In addition to the higher weighing speed and increased precision, the digital controller also offers lower susceptibility to disturbances such as temperature, humidity or wind. The legal-for-trade checkweigher models equipped with this load cell upgrade are, due to the reduced minimum weight, very well suited for dynamic weighing with low-weight products, such as in the confectionery industry or canned products. In other industries such as pharmaceuticals, chemicals or cosmetics manufacturing, the reduced minimum weight, together with support for higher belt speeds, increases efficiency and throughput. Minebea Intec’s checkweighers are highly precise and provide reliable control for numerous weighing applications, completeness checks and filling process optimisations, allowing customers to optimise their output and efficiency.
Will the new load cell be available to equipment manufacturers?
As we said, with MID certification for legal-for-trade applications, the WZED load cell is certified for belt speeds of up to 3 metres per second, processing speeds of 600 products per minute. Thanks to the integration into the weigh cell housing, the new electronics of the load cell consumes less space and at the same time allow for better cleanability, in accordance with Hygienic Design. The new housing allows for easy installation and improved accessibility of the load cell for servicing or in case of maintenance. Initially, this upgrade will reach all Minebea Intec checkweigher series. However, this is only the beginning, as Product Manager Sara Vivanco said: the WZED upgrade is a concrete testimony that the company always tries to get the maximum out of it. Checkweighers with EMFC weighing technology have always scored with maximum precision and reliability – but with the WZED upgrade as an integrated component, Minebea Intec are opening a new chapter. And Vivanco gives a small glimpse into the exciting future: “We also plan to make the new load cell available to equipment manufacturers. The variety of available interfaces makes the WZED ideal for integrating into existing plants in the future”.
