Hygienic Load Cell and Mounting Kit: Contego

A special design feature is the consistent implementation of the construction principles for hygienic design according to the specifications of the European Hygienic Engineering Design Group (EHEDG).

Additionally, no compromises were made in selecting the materials. They are oriented towards internationally certified standards and provisions as well. The Contego® mounting plates are made of stainless steel grade 1.4404 and provide solid protection against corrosion even when using strong cleaning agents.

The protective cover made of FDA-compliant silicone ensures a reliable encapsulation of the module and prevents the intrusion of dirt and microorganisms. The well thoughtout connecting geometry between protective cover and mounting plates guarantees a safe fitting and, together with the already excellent resistance to aging of the silicone, ensures reliable protection over years.

The Contego® weighing module therefore represents an absolutely hygienic unity of load cell and installation kit. As a result, you can refrain from using other expensive and complicated constructions to protect the weighing technology against dirt.

Besides the hygienic aspect, the Contego® weighing module provides all the other important mechatronic functions for a fast operational startup and reliable results. Therefore, this weighing module has an integrated constrain, which holds the process vessel in the proper position and, at the same time, allows movement through thermal expansion of the vessel. The integrated lift-off protector is a reliable safety feature to protect the vessel from tilting. At the same time, this feature can be used as a lifting system as well. This way, the vessel leg can be raised a few millimeters without using supplemental tools.

A PR 6241 S-type load cell is used with this module. This series is distinguished by its unmatched reliability, robustness and stability, enabling years of undisturbed usage without any readjustment, not to mention the high measuring accuracy and reproducibility.

Application
The Contego® Hygienic Weighing Module has been designed especially for the instrumentation of process vessels in which ease of cleaning and avoidance of hygienically critical areas are highly important for a safe and efficient production process.

The weighing module can be used for all types of process vessels such as production, mixing, charging and storage vessels, as well as intermediate and permanent storage tanks. The use of the hygienic weighing module allows a significant reduction in cleaning effort and, at the same time, decreases the contamination risk for products.

The use of high-quality materials provides high chemical resistance and therefore guarantees reliable long-term use, even when cleaning frequently with aggressive cleaning agents.
