Type ANV / ANH
Magnetic Level Switches
Features and Benefits
• Horizontal or vertical tank mounting allows for
flexible mounting options
• Certified material, NACE, radiography options
to meet Customer specifications
• Certified explosion-proof or intrinsically safe
Description
The vertical (Series ANV) or horizontal (Series ANH) level
switches are designed to detect level variations in tanks
containing liquids. The alarm switches activate electric
or pneumatic circuits to switch relays, pumps, electric
valves or control luminous signal or alarms. They can
be used for normal, corrosive or hazardous liquids.
A stainless steel float follows the level of the liquid and
transmits its movement to a rod equipped with an emitter.
The rod and emitter assembly moves into a scaled, nonmagnetic
guide-tube and magnetically activates the
switch which is protected by a water-proof case-housing.
ANV / ANH Magnetic Level Switches
Principle of Operation
The ANV models must be mounted vertically, either
directly on the top of the tank (series ANV-T) or on the
side of the tank through an independent chamber fitted
with two side connections (series ANV-C)
The ANH models must be mounted horizontally, directly
on the side of the tank or through an independent chamber
(type ANH-C).
