Series B40 External Caged Liquid Level Switch
B40 liquid level switch is specifically designed and constructed for high-pressure, high-temperature service conditions. These type level switches are completely self-contained units designed for side mounting to a tank or vessel with welded or flanged pipe connections.
Operating Principle
As the counter weighted float follows liquid level changes, a magnetic sleeve is moved into or out of the field of a switch-actuating magnet causing switch operation. A non-magnetic barrier tube isolates the switch mechanism from the controlled liquid.
