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 = 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.
