McDonnell & Miller RS-2-BR-1 Remote Sensor

For high-performance liquid level control in commercial boilers and hydronic systems, the McDonnell & Miller RS-2-BR-1 Remote Sensor (Part Number 179525) provides industrial-grade reliability. This two-level remote sensor probe holder is engineered with a 2" NPT tank connection, making it a drop-in solution for tanks and vessels requiring precise high and low level detection. Built to withstand demanding boiler room environments, it features a NEMA 4X enclosure for superior protection against moisture and corrosion. Designed for seamless integration with series 750, LPC-2000, or PCH/PCL liquid level control units, this unit handles a maximum pressure of 250 psig and operating temperatures up to 406°F. As a veteran technician knows, the remote sensor configuration allows for flexible mounting away from the control unit, ensuring the low water cut-off sensor remains accurate even in high-vibration or tight-clearance applications. This probe holder requires McDonnell & Miller "P" series probes, which are sold separately to allow for custom length field adjustments.

• Durable Brass & NEMA 4X Construction: Provides long-term environmental protection and prevents scale bridging in high-pressure hydronic systems.
• Two-Level Monitoring: Supports both high-level alarm and low-level cut-off functions within a single 2" NPT mounting point.
• Versatile Application: Optimized for use in steam boilers, hot water systems, and industrial storage tanks with high-heat requirements.
• Maintenance-Free Design: No blow-down is required for the sensor itself, reducing the contractor's routine service time.

• Does this include the sensor rods? No, the RS-2-BR-1 is the probe holder and enclosure only. You must purchase the stainless steel "P" series probes separately based on your required insertion depth.
• Can I use this for high-temperature steam? Yes, the unit is rated for saturated steam at 250 psi and temperatures up to 406°F.
• Is this compatible with 120V or 240V systems? The sensor is a passive component; compatibility depends on the McDonnell & Miller 750 series or equivalent control unit you are wiring it to.
