DEScRipTiOn
Magnetrol's B40 liquid level switch is specifically designed
and constructed for high pressure, high temperature service
conditions. (It is suitable for use on 0.65 minimum specific
gravity liquids).
OpERaTing pRincipLE
B40 level switches employ permanent magnetic force as the
only link between the float and the switching element. As
the pivoted float follows liquid level changes, it moves a
magnetic sleeve ¨ into or out of the field of a switch
actuating magnet ≠ causing switch operation.
A non-magnetic barrier tube Æ effectively isolates the switch
mechanism from the controlled liquid.
