The Sliding Connection (Figure ) ) External length of sliding connection Insulation Insulation ) Free external length of sliding connection see curve below ) ) 4) Lumpy or sticky media 4) Lumpy or sticky media ) The drawing shows how the sliding connection can be used for at least 4 applications: ) Mounted at the top of a tank to adjust to a maximum level. ) Serving as a cooling neck in high media temperature applications. ) Adjusted to place the sensor tip deeper inside the tank. 4) To reach in through insulation material. It is essential that the max. ambience temperature for the electronics is never exceeded. For ATEX approved products please refer to table. ) Example, how to read Curve : A 50 mm sliding connection is mounted in a tank with a total insert length of 50 mm. Hence the external length of the sliding connection will be 50 50 = 00 mm. The media temperature will be max. 60 C. ead the xaxis at 00 mm an the yaxis at 60 C and find that the ambient temperature must be kept below 50 C. In case the radiated heat from the tank will cause a higher ambient temperature at the housing efficient insulation of the tank must be established The working conditions for the sliding connection in different media temperatures and specified ambient temperatures can be found in curve.
