Warrick 3L1D12 Liquid Level Accessory

The Warrick 3L1D12 is a professional-grade liquid level control electrode engineered for high-accuracy sensing in conductive fluid applications. This conductivity-based level sensor features a single 12-inch 316 stainless steel probe rod, providing superior corrosion resistance in demanding HVACR and industrial environments. Designed with high-performance Teflon sheathing, the electrode ensures reliable electrical insulation and prevents false bridging caused by vapor or foam. The assembly includes a secondary 1/8" NPT tank connection for secure mounting into pressure vessels or tanks, paired with a 3/16" female thread probe connection for easy maintenance. As a direct field-trimmable replacement for the shorter 3L1D02 model, the 12-inch rod allows technicians to customize the sensing depth on-site to meet specific high-limit or low-water cut-off requirements. Rated for 150 PSI at 365°F, this compact electrode fitting is built for the rigors of boiler feed systems, condensate tanks, and pump control circuits.

• Corrosion-Resistant Construction: The 316 stainless steel probe and housing offer maximum longevity when exposed to aggressive water chemistries.
• Field Versatility: The 12-inch rod is fully trimmable in the field, allowing it to replace 2-inch or custom-length probes without ordering separate SKUs.
• Teflon Insulation: High-grade sheathing maintains dielectric strength at temperatures up to 365°F, ensuring precise signal transmission to the controller.
• Compact NPT Mounting: The 1/8" NPT bushing allows for installation in tight spaces where larger flange or NPT fittings are impractical.
• Direct OEM Compatibility: Serves as a streamlined replacement for legacy 3L series components, ensuring seamless integration with existing Warrick conductivity relays.

Can I use the 3L1D12 to replace the 3L1D02 in my existing tank?
Yes. The 3L1D12 is the direct technical replacement for the 3L1D02. While the 3L1D02 came with a 2-inch probe, this 12-inch version allows you to trim the rod to the exact 2-inch length (or any length up to 12 inches) required for your specific application.

Is this probe compatible with non-metallic tanks?
When installing in a non-metallic or lined vessel, you must ensure a ground reference is established. This is typically done by adding a second probe to serve as the common ground or by using a metallic fitting connected back to the liquid level controller’s ground terminal.

Do I need special tools to shorten the probe rod?
A standard hacksaw or pipe cutter can be used to trim the 316 stainless steel rod. After cutting, ensure you strip back the Teflon sheathing slightly to expose the tip for proper conductivity sensing.
