Hydrolevel EL1214-R 3/4" Low Water Cut-Off Probe with Junction Box

The Hydrolevel EL1214-R is a 3/4 inch National Pipe Taper (NPT) remote mount probe with junction box and cover designed for use with low water cut-off systems in residential and commercial boiler applications. This 3/4" NPT ceramic sensing probe provides reliable water level detection to protect boilers from dangerous low water conditions.

Key Features:

• 3/4" NPT Standard Ceramic Probe in Junction Box w/Metal Cover (2-7/8" ID)
• Remote mount design with pre-wired junction box for simplified installation
• Durable ceramic construction for long-lasting performance
• Compatible with Hydrolevel Safgard low water cut-off controls
• Standard inside dimension fits most boiler applications

A probe is installed in the boiler shell or external manifold and is connected to the control unit. Water is used as a conductor to complete the circuit between the probe and the boiler shell. When water is in contact with the probe, the circuit is completed; when the water level drops below the probe, the circuit opens. This electronic sensing method provides accurate, reliable low water detection without moving parts that can wear, stick, or malfunction.

The EL1214-R includes a protective junction box with metal cover for secure mounting and electrical connections. This complete assembly simplifies installation and replacement of sensing probes in existing low water cut-off systems. Regular maintenance includes annual inspection and cleaning of any scale buildup from the probe surface.
