Hygienic fittings designed for food

Bourdon-Haenni has introduced its In-Line system of sensor fittings for hygienic pipelines in the food processing industry.

Bourdon-Haenni – a new company formed by the merger of Bourdon Sedeme, Haenni Instruments and Kamstrup Process – has introduced its In-Line system of sensor fittings for hygienic pipelines in the food processing industry.

Easily welded into process piping, the In-Line components comprise a short length of pipe (between 170 and 490mm, depending on pipe diameters from 38 to 101.6mm) fitted with either one or two integrated unions for industry standard 3A/DN38 connections. These connections allow temperature or pressure sensors to be introduced into the process system with no risk of contamination.

Made from acid-resistant, electropolished stainless steel, the In-Line system complies with the requirements of FDA, EHEDG and is certified 3A, meeting the requirements for cleaning and sterilisation in place and aseptic capability. Each standard connection can accept sensors such as the FlexBar HRT pressure transmitter or CombiTemp temperature sensor. The version with two directly opposed unions enables precise spot measurements of both temperature and pressure.

Each connection is engineered to eliminate any shapes or crevasses that could trap product or cleaning fluids. When fitted with a pressure transmitter, the diaphragm is flush to the walls of the pipe, avoiding any shadow areas.

A specially designed groove and O-ring seals the connection. A leakage detection hole alerts the operator if the O-ring seal should fail.
