Overview
The SeaMetrics FS10 is a magnetic float level sensor designed for dependable liquid level detection and control. The FS10 uses float-based magnetic transmission technology, comprising a guide tube with embedded Reed contacts, floats with fitted ring magnets, and a process connection module. The float rises with liquid level and operates a Reed contact through the guide tube wall via the magnetic field from permanent magnets in the float.
Key Features
- Reed contact can be configured as NO (normally open), NC (normally closed), or changeover function
- Potential free reed contacts make it ideal for use with PLC controllers
- Float stops prevent the float from passing the contact, assuring bistable switching
- Reliable operation in corrosive and demanding environments
- Vertical mounting design for compact installations
