Fig. 19: Radar sensors on traverse crane
Information:
Keep in mind that for these applications, the sensors are designed for
relatively slow level changes. When using VEGAPULS 68 on a mov-
able bracket, the max. measuring rate must be observed (see chapter
"
Technical data
").
Instruments for a temperature range up to 250 °C or up to 450 °C
have a distance piece between process fitting and electronics hous-
ing. Ths distance piece is used for thermal decoupling of the electron-
ics against high process temperatures.
Information:
The spacer may only be incorporated up to a maximum of 50 mm into
the vessel insulation. Only then is a reliable temperature decoupling
guaranteed.
