Level Monitoring
-
Magnetic level switches are used for the monitoring and control of liquid level in tanks. These level switches are specifically manufactured to customer specifications. The float switches are manufactured with a hermetically sealed contact which is located within the guide tube. The float sliding on the tube contains a ring magnet which activates the sealed contact in a non-contacting fashion. The sealed contacts are available as SPST (N/O or N/C) or SPDT (N/O + N/C). The float sliding up and down on the guide tube is the only moving part on the M-series magnetic float switches.
