With the help of limit switches, data can be easily and reliably recalled from the system – for example, on-off information that can be electrically forwarded to the control system.
Our product range includes mechanical, inductive, and magnetic limit switches.
Several operating options
In mechanical models, the motion of the valve stem is tied to the switch that rises or lowers with the motion of the valve and signals the opened or closed state of the valve.
An inductive switch generates an output signal if a metallic or other conductive material approaches the sensing surface.
The operation of magnetic switches is based on changes in the magnetic field while the valve stem rises or lowers. This equipment is also applicable in explosion hazard areas.
