The Warrick 3C2B13 is a heavy-duty brass water column electrode fitting designed for high-performance liquid level control in steam boilers and pressure vessels. As a direct replacement for the legacy 3C2B7, this short external mount side chamber provides a pressure-tight sensing environment, ensuring accurate low water cutoff (LWCO) or high-level alarm functionality. Built with a red brass body and equipped with dual 6-inch 316 stainless steel probes, the 3C2B13 is engineered to withstand demanding industrial conditions, rated for up to 250 PSIG at 406°F. This unit utilizes conductivity-based sensing, where the liquid completes a circuit between the probes to trigger control relays. For field technicians, the 13-inch overall length and 1/2" NPT conduit connection allow for straightforward integration into existing hydropneumatic tanks or boiler water columns. When wiring, ensure the use of #14 or #16 AWG MTW or THHN copper wire to maintain signal integrity between the electrodes and the remote controller. Key Benefits for the Contractor: Direct Retrofit Compatibility: Seamlessly replaces the Warrick 3C2B7, minimizing repiping and downtime during field upgrades. Superior Material Durability: The red brass chamber resists corrosion and scale buildup, while 316SS probes with Teflon insulation ensure long-term conductivity. Versatile Application Range: Ideal for boiler feedwater control, condensate return tanks, and pump-up/pump-down sequencing in pressurized systems. Reliable Sensing Performance: Rated for high-pressure 250 PSIG service, providing precise differential level control without the failure points of mechanical floats. Common Questions & Troubleshooting: How do I adjust the sensing height for the probes? The 6-inch probes are fixed length; however, the 3C2B13 is designed for side-chamber mounting where the water level equalizes with the vessel. Verify your vertical alignment to ensure the dual probes hit your low and high setpoints. Can I use this for non-boiler applications? Yes, but ensure the liquid sensitivity matches your controller (e.g., 26K or 50K ohm). It is effective in any conductive medium like wastewater or process chemicals. Why is the relay not triggering even when the chamber is full? Check for probe bridging caused by mineral deposits or scale; cleaning the stainless steel electrodes often restores circuit continuity.
