Bamo MNR 7 Magnetic Level Controllers

Bamo MNR 7 Magnetic Level Controllers The Reed contacts (up to 4) inside the stem, are actuated directly by the magnet float. Wet parts (stem and float) to choose between: or PVC & PP, or PP, or PVDF.

Bamo MNR 7 Magnetic Features

Versions in: PVC, PP or PVDF
1 to 4 level changeover contacts
Fitting 2” for standard models
No effects of foam, neither of vapours
Measuring height: up to 2500 mm

Quick commissioning:

Distance of each contact from sealing surface is fixed (requested on P.O.): No adjustment requested on site to guarantee the exact positioning of contacts.
The PP float passes through the BSP 2” fitting without dismantling the MNR.
At the stem bottom a nut limits the float movement: By unscrewing it, the float may be removed. Note: It is recommended to provide the optional flange ND100 to allow the PVDF float to pass through the fitting.

Recommendations:

The use of a relay ES2001 will protect the Reed contact and increase its switching power and lifetime.

Application

Level controllers for liquids, even aggressive ones, not viscous, not clogging and free of suspended solid particles.
