 Merry-go-around, also in dusty atmosphere


The ATEX-approved level switch NIR-9 monitors a wide range of applications for
bulks and solids in silos and hoppers regardless of humidity and conductivity of the product.

A synchronous motor drives a shaft at which a rotating vane is fastened at the lower end. When this rotating vane is decelerated or stopped by bulk solid, the engine moves over the pivoted gear from one end position to the other and thereby switches two microswitches, one shutting down the engine and the other providing an alert signal for display of limit level.
When fill level decreases, rotating vanes are released again and motor is pulled into its primary position by the force of a spring. Thereby the motor is switched on again and working contact is switched back.

The mechanical connection is via flange or screw connection without any problem. The drive shaft can be elongated up to 4 meters.

Different rotating vane shapes enable optimum adjustment to bulk solid.
All wetted parts are of stainless steel and therefore allow operation even with aggressive chemical bulk solids. The model is ATEX-approved and allows operation in a dust-explosive environment (zone 21/22).
Depending on selected options, the devices may be used over the entire medium temperature range of –20°C to +200°C.
