MAGNETROL B60-2C20-JEE

Flanged External Cage
Float Actuated
Liquid Level Switches
DESCRIPTION
External cage type level switches are completely selfcontained units designed for side mounting to a tank
or vessel with threaded or flanged pipe connections.
In hundreds of industrial applications throughout the
petroleum refining, petrochemical production and
power generation markets, these switches have
thoroughly demonstrated their worth for years.
FEATURES
• Carbon steel float chamber.
• Easy inspection of float chamber through
removable head.
• Stainless steel float and trim.
• Service pressures up to 900 psig (62 bar).
• Process temperatures up to +1000° F (+538° C).
• Specific gravity ratings as low as 0.40.
• Available switch styles including dry contact,
hermetically sealed and pneumatic.
• Operating level differentials field-adjustable.
• Single or multiple switch mechanisms available.
• Available switch enclosures include:
NEMA 1 carbon steel for pneumatics

TECHNOLOGY
A permanent magnet Œ is attached to a pivoted
switch actuator and adjustment screw . As the
float Ž rises following the liquid level, it raises the
attraction sleeve  into the field of the magnet,
which then snaps against the non-magnetic
enclosing tube , actuating the switch ‘. The
enclosing tube provides a static pressure boundary
between the switch mechanism and the process.
On a falling level, an inconel spring retracts the
magnet, deactivating the switch.

 IEC Installation Instructions:
The cable entry and closing devices shall be Ex d certified suitable for the conditions of use and correctly installed.
For ambient temperatures above +55° C or for process temperatures above +150° C, suitable heat resistant cables shall be used.
Heat extensions (between process connection and housing) shall never be insulated.
Special conditions for safe use:
When the equipment is installed in process temperatures higher than +85° C the temperature classification must be reduced
