Hygienic

Hygienic measurement instrumentation are designed for use by the food, drink and pharmaceutical industries, which require a high level of cleanliness in their manufacturing processes.

Hygienic applications require that all parts in contact with the process media must have a high level of cleanliness and include precautions against contamination.

To maintain hygiene in production processes, equipment needs to be designed so that it is possible to easily clean all parts in contact with the process media. Also the contact surface of these parts should deter the build up of bacteria and mould and other pathogens that may cause harm to human health.

Hygienic instruments have highly polished stainless steel parts exposed to the process media and are installed using clamped seals.

Direct threaded type fittings are avoided since they introduce crevices which would attract the build up of process material over time and require dismantling for cleaning. Threads are used in some types of clamped fittings in order to pull two components together to make a seal, but are only used on the non-contacting external surfaces.
