Hydrolevel EL1220-SV Sensing Probe
The Hydrolevel EL1220-SV is a specialized low water cut-off (LWCO) sensing probe designed for high-performance liquid level monitoring in hydronic heating and steam boiler systems. Featuring a rugged short ceramic insulator, this 45-221 part number is engineered for tight clearance installations where standard probes may interfere with internal castings or piping. The 1/2" NPT threaded connection ensures a secure, leak-proof seal, while the 2 1/16" inside dimension (insertion length) provides precise conductivity sensing without the risk of grounding against the boiler wall.
As a veteran HVAC technician, you know that Hydrolevel 45-221 probe reliability is critical for preventing dry-firing and thermal damage. This replacement sensing probe is fully compatible with Safgard 24, 400, 500, and 700 series controls, as well as CycleGard units. The durable ceramic construction resists scale buildup and corrosion, maintaining high signal integrity even in harsh, mineral-heavy water conditions. When replacing an older boiler water level sensor, the EL1220-SV is the standard for contractors requiring dependable short-probe geometry and industrial-grade durability.
Key Benefits- Engineered for Compact Spaces: The 2 1/16" insertion length is ideal for smaller boilers or reducing tee installations where space is a premium.
- Enhanced Corrosion Resistance: High-grade ceramic insulation prevents mineral bridging and scale-related false signals.
- Direct OEM Replacement: Seamlessly replaces Hydrolevel 45-221 and EL1220-SV models without requiring modification to the existing control.
- Thermal Stability: Designed to withstand the high-temperature and pressure cycles typical of residential and light commercial steam systems.
- Conductivity Sensing Accuracy: Maintains a precise electrical path to the control module for instantaneous low water detection.
What is the difference between the EL1220 and the EL1220-SV?
The standard EL1220 features a 2 7/8" insertion length, while the EL1220-SV (Short Version) has a 2 1/16" length. Use the SV model if your boiler casting or mounting tee has limited depth to avoid grounding the probe.
Can I use this probe with other LWCO brands?
This probe is specifically designed for Hydrolevel Safgard and CycleGard controls. Using it with non-Hydrolevel systems may result in incorrect sensitivity readings or signal failure.
How often should I clean the ceramic probe?
In systems with hard water, we recommend inspecting the probe annually. If you notice calcium or scale buildup on the short ceramic surface, it should be cleaned with a mild abrasive or replaced to ensure accurate water level sensing.
