Warrick 3R2A0 2 FT Brass Probe

For industrial level monitoring, the Warrick 3R2A0 is a specialized 2-foot brass conductivity probe designed for rigid-rod vertical mounting. As a veteran-grade liquid level control sensor, this 3R series metallic rod features a 1/4-20 threaded end, allowing for a secure direct-thread connection into Warrick electrode fittings such as the Series 3E, 3F, or 3B. This solid brass construction provides reliable conductivity and corrosion resistance in applications involving non-corrosive liquids, water storage, or general-purpose steam applications up to 225 psig at 150°F. When used with a compatible induction relay or solid-state controller, the 3R2A0 probe completes the electrical circuit upon liquid contact, providing precise point-level detection without moving parts. For contractors managing boiler feed systems or pump control, this brass electrode rod is the industry standard for maintaining consistent differential levels and high-low alarm setpoints.

• Durable Brass Material: Optimized for electrical conductivity and longevity in non-acidic industrial fluids.
• Universal Compatibility: Standard 1/4-20 threading ensures seamless integration with Series 3E NPT mounting and Series 3F flange fittings.
• Maintenance-Free Design: No moving parts reduce the risk of mechanical failure in turbulent tanks or high-vibration environments.
• Field Adaptability: The 24-inch length can be utilized for deep sensing or trimmed in the field to meet specific tank depth requirements.

Is the 3R2A0 compatible with corrosive chemicals?
While brass is excellent for water and steam, it is not recommended for acidic or highly caustic environments. For such applications, 316 stainless steel or Teflon-sheathed probes (Series 3R2C5) should be utilized to prevent material degradation.

What is the maximum pressure rating for this probe?
When installed in a brass body fitting, the 3R2A0 is typically rated for 225 psig at 150°F. Always verify the rating of the electrode holder housing, as the fitting material often dictates the ultimate pressure and temperature limits.

Can I use this rod with any level controller?
This probe is designed to work with conductivity-based controllers. It is a passive component that facilitates circuit completion. It is specifically engineered for use with Warrick liquid level controllers and induction relays.
