Warrick 3C2B13 Brass Probes

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.

• 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.

• 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.
