上图说明了滑动连接至少可以在4种应用种使用：
1) 安装在储罐顶部，用于调节最高物位。
2) 在高介质温度应用中用作冷却颈。
3) 通过调节将传感器探头放入储罐内部更深的位置。
The drawing shows how the sliding connection can be used for at least
4) 穿过隔热层到达介质。
4 applications:
1) Mounted at the top of a tank to adjust to a maximum level.
确保不超过电子元件所允许的最高环境温度至关重要。要了解通过ATEX
2) Serving as a cooling neck in high media temperature applications.
认证的产品的信息，请参阅表1。
3) Adjusted to place the sensor tip deeper inside the tank.
4) To reach in through insulation material.
如何读取曲线1：举例
3)
长250 mm的滑动连接安装在储罐上，总插入长度为150 mm。因此，滑动
连接的外部长度就是250 - 150 = 100 mm。
介质温度最高160 °C。
Example, how to read Curve 1:
x-轴取100 mm，y-轴取160 °C，对应的环境温度必须保持低于50 °C。如果
A 250 mm sliding connection is mounted in a tank with a total insert
来自储罐的热辐射会在外壳处形成较高的环境温度，则必须在储罐周围
length of 150 mm. Hence the external length of the sliding connection
设置有效的隔热层。
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.
在不同介质温度和给定环境温度的情况下滑动连接的工作条件参见曲线1。
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
