McDonnell & Miller RS-1-HP Sensor

The McDonnell & Miller RS-1-HP Sensor (Part #176199) is a professional-grade single-level high-pressure remote sensor probe holder designed for critical liquid level monitoring in boilers and pressure vessels. Engineered by Xylem for industrial field service, this remote sensor probe holder features a robust 3/4" NPT tank connection and is housed in a NEMA 1 enclosure. Built to handle high-pressure boiler sensor applications, the RS-1-HP supports operating pressures up to 250 psig (17.6 kg/cm²) and temperatures reaching 406°F (208°C). This OEM component ensures reliable signal transmission when paired with a compatible conductance probe rod, maintaining system integrity in high-demand steam or hydronic environments. For a complete installation, field technicians must source the appropriately sized probe rod to meet specific tank depth requirements.

Technical Benefits:

• Heavy-Duty Pressure Rating: Certified for high-pressure sensor probe applications up to 250 psig, ensuring safety in industrial steam systems.
• Thermal Resilience: High-temperature ceramic insulators maintain electrical isolation at 406°F.
• Standardized Integration: The 3/4" NPT connection allows for straightforward retrofitting into existing sensor tapping points.
• OEM Precision: Guaranteed compatibility with McDonnell & Miller 176199 level control systems, eliminating signal drift common in aftermarket alternatives.

Common Questions:

What probe rods are compatible with the RS-1-HP?
The unit is designed for use with McDonnell & Miller G-series or R-series stainless steel probe rods. Selection depends on the required insertion length for your specific low-water cutoff or level-control setpoint.

Does this unit come as a complete assembly?
This is the probe holder and enclosure assembly only. The internal probe rod must be purchased separately based on the required cut length for the application.

Is the RS-1-HP suitable for outdoor installation?
No, the NEMA 1 enclosure is intended for indoor use, providing protection against dust and contact in mechanical rooms or protected plant environments.
