Warrick 3R7C0 Probe Rod

For industrial conductivity-based level control, the Warrick 3R7C0 is the standard-duty 316 stainless steel probe rod engineered for precision sensing in demanding environments. This 84-inch (7-foot) metallic rod features a 1/4" threaded connection, allowing it to screw directly into the fitting and extend vertically into the process liquid. Designed for broad compatibility, this liquid level accessory is the primary sensing element for Series 3E, 3F, 3G, and 3B fittings.

As a veteran tech knows, material integrity is critical; the 316 stainless steel construction provides superior corrosion resistance compared to standard grades, making it suitable for boilers, storage tanks, and industrial fluid systems. At a full 7-foot length, these Warrick 3R7C0 rods can be field-cut to meet specific setpoint depths for high-level alarms, low-level cutoffs, or pump control logic. The 0.25-inch diameter ensures structural rigidity even in high-agitation applications. When replacing older liquid level control probes, ensure your existing fitting threads are clean to maintain a secure electrical path for the conductivity signal.

• High-Grade Media Resistance: 316 Stainless Steel is ideal for corrosive or high-temperature industrial fluids.
• Universal Compatibility: Seamlessly integrates with Warrick Series 3E, 3F, 3G, and 3B fittings.
• Field-Adjustable Length: The 84-inch rod can be cut to the exact depth required for your specific tank geometry.
• Secure Installation: The 1/4" threaded end ensures a reliable mechanical and electrical connection to the electrode holder.

Can the Warrick 3R7C0 be used in pressurized vessels?
Yes, provided it is installed in a pressure-tight fitting such as the Series 3E. The rod itself is solid 316 SS and maintains integrity under standard boiler and tank pressures.

What happens if the probe rod develops scale or mineral buildup?
Buildup can act as an insulator or cause "bridging" between probes. Regular inspection by a technician is recommended to ensure the conductivity-based liquid level control system remains accurate.

Do I need a separate adapter for the 1/4" thread?
The 3R7C0 includes a standard 1/4" threaded end designed to fit directly into compatible Warrick fittings without additional adapters.
