Connection for the Milk Tube Fitting

29 September 2009

Since a new process connection was also required for the new milk tube, the Nestlé PTC developed a special adapter for the ED701 in co-operation with Baumer. Whilst Baumer delivered the connection for the pressure-receiving side, the matching part on the product side was constructed by Nestlé.

"For the milk tube fitting, Baumer offered us the CombiConnect adapter, which we found most suitable thanks to its flush-mounted O-ring", says Ernst Strahm, measurement technologist at the Nestlé PTC in Konolfingen.

The CombiConnect system provides a series of hygienic, replaceable process connections made of acid-proof stainless steelThey can be used with the pressure transmitters FlexBar and ED701 as well as the temperature measuring device CombiTemp. The connections were developed according to the demands of the food industry fulfilling the FDA and EHEDG criteria.

A further challenge this application posed was the very small pipe with a diameter of only 10mm, making it very difficult to clean. The problem was solved with a high flow rate and a pressure transmitter with a small volume compared to that of the tube.
