Hydrolevel EL1214 Sensing Probe

The Hydrolevel EL1214 (also identified as Part Number 45-214) is a heavy-duty 3/4" NPT standard ceramic sensing probe engineered for precise liquid level detection in residential and light commercial boiler systems. Featuring a 2-7/8" insertion length (inside dimension), this probe is a critical component for low water cut-off (LWCO) safety controls, providing the essential conductance signal required to prevent dry firing and catastrophic heat exchanger failure. Constructed with a high-grade standard ceramic insulator, the EL1214 sensing probe resists scale buildup and high-temperature degradation, ensuring reliable electrical continuity between the probe tip and the boiler water.

Designed for seamless integration with Hydrolevel Safgard and 1150 Series controls, this replacement water level sensor utilizes a threaded 3/4 inch NPT connection for a secure, leak-proof fit. As a veteran-preferred HVAC boiler part, it is built to withstand the rigors of hydronic and steam environments. Technicians should note that this standard model provides optimal clearance in most boiler shells, facilitating accurate water level monitoring without the nuisance tripping associated with shorter probes in high-sediment applications.

• Direct Compatibility: Fits a wide range of Hydrolevel Safgard low water cut-offs, serving as a reliable OEM replacement probe.
• Durable Insulation: The standard ceramic body prevents short-to-ground failures caused by moisture or carbon tracking.
• Optimal Insertion: The 2-7/8" inside dimension ensures the probe reaches past the nozzle for accurate sensing.
• Universal Threading: Standard 3/4" NPT male threads allow for straightforward installation in existing boiler tappings.

• Can I use Teflon tape on the threads? It is recommended to use a conductive pipe sealant (like Megalock) rather than Teflon tape, as the probe requires a good electrical ground through the threads to the boiler shell.
• How do I know if the probe needs cleaning? If you experience nuisance shutdowns or the "Low Water" light persists despite proper levels, inspect the ceramic for scale or mineral deposits that may be insulating the tip.
• Will this work in a 1/2" tapping? No, this model is specific to 3/4" NPT. For 1/2" applications, the EL1220 (Part 45-220) is typically required.
