Description
The Xylem-McDonnell & Miller RS-1-HP is a Single Level High Pressure Remote Sensor Probe Holder designed for use with McDonnell & Miller remote-style low water cutoff and water feeder systems. Engineered for high-pressure boiler applications, this probe holder provides a secure, leak-free 3/4″ NPT tank connection that positions the sensing probe at the correct water level within the boiler vessel.
Product Overview
The RS-1-HP probe holder is a critical component in McDonnell & Miller’s remote sensor system, separating the probe assembly from the control head for installations where direct-mount configurations are not practical. Its high-pressure rating makes it suitable for demanding steam boiler environments where reliable water level detection is essential for safe and efficient operation.
Key Features
- Single-level high-pressure remote sensor probe holder
- 3/4″ NPT tank connection for secure boiler vessel mounting
- Designed for high-pressure steam boiler applications
- Compatible with McDonnell & Miller remote-style low water cutoff systems
- Durable construction engineered for long-term reliability in demanding hydronic and steam environments
- Part Number: 176199
Application
The RS-1-HP is intended for use as a replacement or OEM component in McDonnell & Miller remote sensor low water cutoff assemblies on high-pressure steam boilers. It allows the sensing probe to be mounted directly to the boiler shell or vessel while the control head is remotely located, simplifying installation in tight spaces and improving serviceability.
