Hydrolevel EL1214-SV Sensing Probe

The Hydrolevel EL1214-SV is a professional-grade short ceramic sensing probe engineered for precise liquid level detection in hydronic and steam systems. Built with a 3/4" NPT threaded connection, this 45-215 sensing probe features a compact 2 1/16" inside dimension, making it the standard choice for low water cut-off (LWCO) applications where clearance is restricted, such as within a standard reducing tee. The durable ceramic insulator is designed to handle high-pressure environments up to 1000 PSI, providing reliable signal continuity for Safgard 500, 600, and 700 series controllers. This OEM Hydrolevel replacement part ensures accurate water level monitoring, preventing dry firing and potential vessel damage by maintaining a consistent electrical path to the control board. For contractors performing system maintenance, the Hydrolevel EL1214-SV 3/4" NPT probe offers a rugged solution for residential and light commercial boilers that require a shorter insertion depth than standard long-nut alternatives.

• Compact Insertion Depth: The 2-1/16" inside dimension allows for seamless installation in tight clearance areas and standard reducing tees without bottoming out.
• High-Pressure Durability: Rated for up to 1000 PSI, the ceramic construction resists scale buildup and thermal stress in demanding boiler environments.
• Universal Compatibility: Specifically designed to interface with Hydrolevel Safgard 1150, 170, 24, and 500-750 series low water cut-off controls.
• Enhanced Conductivity: The 3/4" NPT short ceramic probe maintains a high-integrity electrical circuit to ensure the burner shuts down immediately if water levels drop below the safety limit.

• Can I use Teflon tape on the probe threads? It is recommended to use a pipe sealing compound instead of Teflon tape. Excessive tape can insulate the probe from the boiler shell, breaking the ground circuit and causing the control to malfunction.
• How do I maintain the sensing probe? To ensure optimal performance, remove and inspect the probe annually. Clean any sediment or mineral scale from the ceramic and metal surfaces using a scouring pad or steel wool.
• Will this probe work in a horizontal header? Yes, the EL1214-SV can be mounted in vertical or horizontal piping. Ensure there is at least 1/4" clearance from the probe tip to any internal boiler surface or pipe wall.
