The material used in the construction of a measuring instrument is an important consideration, especially when the instrument is to be used in food processing.
Stainless steel is used most often for instruments and equipment which come in contact with food. Both 316 and 316K have become accepted internationally in food applications. However, there are a number of reasons other metals may be used in various parts of a process, for example certain applications require the thermal conductivity of copper or the robustness of standard steel.
Plastics are indispensable, both as a material for seals, as an insulating layer for certain measuring techniques and for use in highly aggressive media. Although plastics may be totally resistant, they can be severely damaged by products or cleaning media. The guidelines of the Food and Drug Administration (FDA) on the use of plastics in food production are internationally recognized. 3-A also publishes proposals regarding the selection of materials.
For more than ten years, teams of Endress+Hauser instrumentation specialists have worked together to focus on the international requirements of individual industries. This know-how is used both to advise and support our food and beverage customers as well as to guide Endress+Hauser's research and development efforts.
