The Warrick 3E5B Series 3E is a heavy-duty, pressure-tight electrode fitting designed for dependable liquid level control in demanding industrial environments. Engineered with a robust red brass body, this 3-inch NPT multi-probe fitting accommodates up to five electrodes, making it a staple for contractors managing complex boiler feed, pump control, or wastewater systems. Its cast metal construction ensures a secure, leak-proof seal capable of withstanding operating pressures up to 250 psig at temperatures reaching 406°F. This specific 3E5B model is optimized for use with 3R rigid rods or 3W wire suspended electrodes, providing the flexibility needed for deep tank or high-vibration applications. In the field, the Warrick 3E5B is valued for its terminal housing accessibility, allowing technicians to quickly land 14 or 16 AWG wiring on the internal lugs. By utilizing the liquid's own conductivity, this fitting facilitates precise level detection without the failure points found in mechanical float switches. Key Benefits Five-Probe Capacity: Allows for multi-point level control, including high/low alarms and pump start/stop cycles from a single vessel entry. High-Temperature Rating: Rated for 406°F, making it suitable for steam boiler and high-pressure condensate applications. Corrosion Resistance: The red brass composition provides superior durability against scaling and oxidation compared to standard cast iron. Versatile Mounting: The 3" NPT male threading integrates seamlessly into existing industrial tank ports and process piping. NEMA Construction: Features a die-cast aluminum epoxy-coated terminal housing to protect electrical connections from moisture and debris. Common Questions What type of electrodes are compatible with this fitting? The 3E5B is designed to work with Warrick 3R rigid rods or 3W wire-suspended electrodes. For rigid rods, ensure you select the appropriate material (such as 316 Stainless Steel) for your specific chemical media. Does this fitting require a specific controller? Yes, this fitting acts as the sensor interface and must be wired to a Warrick conductivity-based level control relay (such as the Series 16 or 26) to manage the pump or valve logic. Can I use this in a non-metallic tank? Yes, but when installing in plastic or fiberglass tanks, a reference probe must be used as a ground to complete the electrical sensing circuit through the liquid.
