Hydrolevel EL1214-LSV Sensing Probe

The Hydrolevel EL1214-LSV Sensing Probe (Part Number 45-227) is a professional-grade low water cut-off sensor engineered for hydronic and steam boiler applications where space is at a premium. As a veteran-preferred short ceramic sensing probe, this unit features a 3/4" NPT threaded connection and a compact 2-1/16" inside dimension (insertion length). This specific geometry is designed for seamless integration into standard reducing tees and low-clearance boiler tappings, ensuring the metallic probe tip maintains at least 1/4" clearance from internal baffles or pipe walls to prevent false grounding.

Constructed with high-density ceramic insulation, the 45-227 probe provides superior resistance to scale buildup and corrosion, which is critical for maintaining signal integrity in high-temperature steam environments. This replacement sensing probe is compatible with various Hydrolevel Safgard control systems, effectively monitoring water levels to prevent dry firing and heat exchanger damage. Its solid-state design eliminates the mechanical failures common in float-style switches, providing contractors with a reliable HVAC water level sensor that requires minimal annual maintenance beyond simple cleaning with a scouring pad.

Key Benefits

• Compact Insertion Depth: The 2-1/16" length is purpose-built for short clearance installations and standard 3/4" tees.
• Industrial Ceramic Build: High-grade ceramic prevents electrical tracking and withstands aggressive boiler water chemistry.
• Reliable Signal Transfer: Threaded 3/4" NPT connection ensures a secure, leak-proof mechanical fit and a consistent electrical ground.
• Preventative Safety: Vital component for boiler low water cut-off logic, protecting equipment from catastrophic dry-fire conditions.

Common Questions

• Will this probe work in a standard tee? Yes, the EL1214-LSV is specifically designed for 3/4" reducing tees where a standard 2-7/8" probe would be too long.
• Does it require specialized tools for installation? No, it installs into a standard 3/4" tapping. Ensure you use pipe sealant on the threads rather than excessive Teflon tape to maintain a proper ground.
• How often should the probe be inspected? For optimal performance, a technician should inspect and clean the ceramic and metal tip annually to remove any sediment or scale.
