Material heaps
You can detect large material heaps using several sensors which you can installed on crane beam, for
example. For material cones it is a good idea to align the sensors as perpendicular as possible to the surface
of the solids. The sensors will not affect each other.

Information
For these applications you should remember that the sensors are designed for relatively slow changes of level.
If the Nico 30 is used on a moving arm, you should note the maximum measuring rate (see section entitled
"
Technical data
").
Installation in the vessel insulation
Devices for a temperature range up to 250 °C or up to 450 °C have a spacer between the process connection
and electronic housing. This is designed to ensure the thermal isolation of the electronic system from the high
process temperatures.
Information
The spacer may only be inserted into the vessel insulation by a maximum of 50 mm. This is the only way to
ensure reliable thermal isolation.
