McDonnell & Miller RS-3-BR-1 Remote Sensor

The McDonnell & Miller RS-3-BR-1 (Part Number 179526) is a heavy-duty three-level remote sensor probe holder designed for high-demand industrial and commercial boiler applications. Engineered to integrate seamlessly with 750 Series LPC-2000, PCH, and PCL liquid level control units, this sensor is a critical component for achieving precise multi-level sensing in tanks and hydronic systems. Featuring a rugged 2" NPT tank connection and a NEMA 4X enclosure, it is built to withstand harsh environments where reliability is non-negotiable. This liquid level control accessory manages up to three "P" series probes, allowing for customized setpoints across a broad range of fluid levels. Designed for high-pressure environments, it maintains operational integrity up to 250 psi (steam or water) and can handle extreme temperatures reaching 406°F. This probe holder is an essential solution for contractors requiring low water cut-off protection and sophisticated pump control in complex thermal systems without the need for manual blow-down.

• High-Pressure Durability: Rated for 250 psig maximum pressure, making it suitable for high-pressure steam and water boilers.
• Multi-Level Versatility: Supports three independent probes for sophisticated pump-on, pump-off, and low-water alarm configurations.
• Corrosion Resistance: Equipped with a NEMA 4X enclosure to protect internal connections from moisture, dust, and corrosive elements.
• Simplified Installation: Standard 2" NPT threaded connection ensures a secure fit into existing boiler tappings or tank headers.
• Broad Compatibility: Fully compatible with industry-standard McDonnell & Miller P-Series stainless steel probes (sold separately).

• Does this include the probe rods? No, the RS-3-BR-1 is the probe holder and enclosure only. Stainless steel "P" series probes must be ordered separately based on your specific length requirements.
• What level controls is this compatible with? It is designed to work with 750 Series, LPC-2000, and PCH/PCL liquid level control and low water cut-off units.
• Can this be used for high-temperature steam applications? Yes, it is rated for temperatures up to 406°F, specifically for high-pressure steam environments.
