McDonnell & Miller 176208 Probe Rod

The McDonnell & Miller 176208 is a professional-grade 4-1/2" 316 stainless steel probe rod (Model P-1/3-SS) engineered for high-accuracy liquid level detection in demanding boiler and industrial vessel environments. Designed as a direct replacement component for RS series sensors, this probe integrates seamlessly with PCH, PCL, and LPC-2000 series liquid level controls to ensure consistent conductance-based monitoring. Its 316 stainless steel construction provides superior corrosion resistance and structural integrity under high-pressure conditions up to 250 psig. For technicians managing low water cut-off (LWCO) systems, this probe offers a reliable metal-to-metal seal when paired with standard brass hex adapters, minimizing the risk of signal loss or mechanical failure in steam and hot water applications.

• Corrosion Resistance: High-grade 316 stainless steel ensures longevity even in harsh chemical or high-temperature feedwater environments.
• System Compatibility: Explicitly designed for McDonnell & Miller RS sensors used in remote level sensing configurations.
• Precision Sensing: The 4-1/2 inch length is optimized for critical height monitoring in small tappings or dedicated sensor chambers.
• Conductance Reliability: Provides a stable electrical path for liquid level controllers to prevent dry-fire conditions in commercial boilers.

Can this probe be cut to a shorter length?
Yes, field technicians often trim these stainless steel probe rods to meet specific low-water cut-off elevations prescribed by the boiler manufacturer.

Is this compatible with non-McDonnell & Miller controls?
While designed for RS series sensors, it functions as a standard conductive probe; however, matching it with McDonnell & Miller PCH or LPC series controls ensures calibrated performance.

What is the maximum pressure rating for this probe?
When installed within the appropriate RS sensor housing, it is typically rated for steam applications up to 250 psig.
