Here’s a replacement for float level switches – Solartron’s Hydratect 2462. It’s a twin-electrode device with fault tolerance for steam drums, feedheaters, de-aerators, etc. It’s self-monitoring and requires no maintenance.
All electronics are in a wall-mounted IP65 stainless steel unit, and six LEDs indicate electrode status and fault conditions.
