Large material heaps are detected with several sensors, which can be
mounted on e.g. traverse cranes. For this type of application, it is best
to orient the sensor toward the solid surface. A mutual infuence of the
sensors is not possible.

Information:
Keep in mind that for these applications, the sensors are designed
for relatively slow level changes. When using VEGAPULS SR 68 on
a movable 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 distance piece must only be incorporated up to max. 50 mm in
the vessel isolation. Only then, a reliable temperature decoupling is
guaranteed.
