Premium Honeywell 48-3250-60 12 Inch Hydrostat Sensor

The Honeywell 48-3250-60 is a 12-inch immersion sensor designed for use with the Hydrolevel 3200 Hydrostat boiler control system. This sensor monitors water temperature or water level conditions within a hydronic heating boiler, providing the Hydrostat control with the input it needs to manage burner operation and protect the system. Licensed heating technicians and boiler service professionals install this component as part of a complete low-water cutoff or operating control assembly. The 12-inch insertion length is suited for standard residential and light commercial boiler installations where correct sensing depth is critical to accurate system response.

This sensor is intended for hydronic heating systems equipped with the Hydrolevel 3200 Hydrostat control. It is installed directly into the boiler pressure vessel or associated piping at a depth of 12 inches, enabling the control to monitor operating conditions and respond to unsafe or out-of-range situations. Typical applications include residential gas and oil-fired hot water boilers in forced hot water heating systems.

Key Features

• 12-inch insertion length sized for proper sensing depth in standard boiler installations
• Designed as a direct accessory for the Hydrolevel 3200 Hydrostat boiler control
