Eilersen has announced it is releasing a new series of digital load cells in a hygienic (aseptic) design for dynamic and process weighing, filling, packaging, and general weighing applications targeted primarily at food and pharmaceutical customers.
The European Hygienic Engineering and Design Group (EHEDG) compliant design is unique without any exposed grooves, threads, or hidden crevices, facilitating easy cleaning to minimise risks of bacteria and contamination on the load cells and ensuring an overall high level of hygiene.
All Eilersen load cells are developed and manufactured in Denmark and based on a highly accurate and very robust capacitive measuring principle. This technology allows an installation without complicated, non-hygienic stay rods, checking assemblies, and overload protection devices, which are used in most strain gage load cell installations. All of these devices can result in a non-hygienic final installation.
The absence of overload protection devices simplifies installation, while making the load cells easy to commission within a hygienic environment.
Patent-pending hygienic compression load cells
The new range of Eilersen type CL and CM compression load cells is based on a patent-pending capacitive sensor design, which provides high accuracies and a very high tolerance to overloads and sideloads.
In combination with the hygienic design that meets EHEDG principles and guidelines, these features ensure quick and easy cleaning, minimising the risk of product contamination and maximising safety. This reduces the risk of expensive discard or product recall, and production waste is minimised as a result, which saves time, money, and reputation.
The CL and CM range was developed for use in primarily food, pharmaceutical, and biotechnology installations but can be used in general industry to measure compression loads or forces. The load cells come in capacities up to 25000kg and are produced in electro-polished stainless steel, while being hermetically sealed (IP68) by laser welding.
In order to ensure a smooth mechanical installation, the new type CL and CM load cells can be supplied with a stainless steel base plate that matches the hygienic design and facilitates installation on almost any surface.
Load cells types CL and CM are ATEX certified for installation in ATEX zone 1, 2, 21, and 22. New application-specific integrated circuit (ASIC) provides optimal specifications during development of the new range and the specifications have been optimised through a proprietary ASIC, which is manufactured for Eilersen utilising the newest technologies.
Flexible instrumentation
The new load cells can be supplied with the most common fieldbus interface options such as PROFINET, Profibus DP, EtherNet IP, and Modbus TCP. In addition, the new load cells can be supplied with a range of digital weighing terminals, which include standard firmware for most weighing applications or customised firmware.
Reliable capacitive technology
Eilersen has more than 40 years’ experience as experts in industrial weighing, with capacitive load cells known for a simple mechanical and electrical installation, reducing both the overall installation cost and minimising maintenance costs.
These characteristics are known and appreciated by satisfied users in more than 85 countries worldwide.
