The Sliding Connection (Figure 1)
The drawing shows how the sliding connection can be used for at least
4 applications:
1) Mounted at the top of a tank to adjust to a maximum level.
2) Serving as a cooling neck in high media temperature applications.
3) 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 1.
The working conditions for the sliding connection in different media
temperatures and specified ambient temperatures can be found in
curve 1.
Media Temperature versus External Length of Sliding Connection (Curve 1)

Example, how to read Curve 1:
A 250 mm sliding connection is mounted in a tank with a total insert
length of 150 mm. Hence the external length of the sliding connection
will be 250 - 150 = 100 mm.
The media temperature will be max. 160 °C.
Read the x-axis at 100 mm an the y-axis at 160°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.
