Why Buy From Us
Every quote personally reviewed. Direct sourcing from top manufacturers.
Maintain precise liquid level monitoring in your hydronic system with the McDonnell & Miller 354081, also known as the PA-800 probe assembly. This component is engineered to serve as a critical sensor for low water cutoff controls, ensuring that your boiler equipment operates within safe parameters by detecting probe contact with water.
The probe functions as a conductive sensing element that completes an electrical circuit when submerged in water. As the water level drops and contact is broken, the control unit interprets this signal change to interrupt the burner circuit, providing reliable protection against dry-firing and potential heat exchanger damage.
Key System Performance Baselines:
- Durable Construction: Engineered to withstand harsh internal boiler environments for long-term reliability.
- Precise Conductivity: Designed to maintain signal integrity for accurate low water cutoff switching.
- Seamless Integration: Optimized for use with compatible McDonnell & Miller control systems for simplified maintenance.
ā ļø Application Profile: Recommended for use in commercial and residential steam or hot water boiler low water cutoff assemblies, particularly where frequent cycling or sediment exposure is a factor.
