Danfoss KPI 35 Pressure Switch (Product Code: 061B010266)
The Danfoss 061B010266 is a heavy duty, industrial grade KPI 35 Pressure Switch engineered by Danfoss for regulating, monitoring, and alarm signaling systems in commercial and industrial settings. It is specifically optimized for fluid and gaseous media (such as water, air, and light oils), making it a staple component in booster pump sets, plant ventilation systems, and heating installations. This electromechanical device translates fluid pressure variations directly into crisp snap action electrical switching loops.
Key Features
-
Dual-Scale Calibration Faceplate: Features clear, high contrast internal sliding scale bars visible through a transparent viewing window, allowing operators to verify setting configurations effortlessly.
-
Independent Range and Differential Regulation: Outfitted with top mounted adjustment screws to independently calibrate the primary target pressure setting alongside the reset differential (hysteresis) window.
-
High Reliability Snap Action Contact System: Built with an ultra fast SPDT (Single Pole Double Throw) silver plated contact arrangement that minimizes contact arcing and resists high vibrational wear.
-
Robust Enclosure Construction: Protected by a rigid composite outer shell rated up to IP30 enclosure protection standards to shield the mechanical pressure bellows from common industrial contaminants and dust settling.
-
Flexible Mounting Configurations: Structured with a heavy metallic lower connection foot featuring a standard pressure port thread for seamless mounting to pipe manifolds or bracket panels.

Applications
-
Commercial Building Water Booster Sets: Controls water supply systems by signaling multi stage pumps to cut in when pipeline pressures drop below target baselines, and shut down upon reaching top capacity.
-
Industrial Air Compressor Units: Acts as an automated low to medium range pressure monitor to ensure pneumatic loop pressures remain stable during peak production cycles.
-
HVAC Facilities Boiler & Chiller Plants: Monitored within centralized cooling and heating circuits as a pressure limit switch to safe stop heavy equipment or sound alarms during sudden system leaks.
-
Hydraulic System Safety Interlocks: Integrated into low pressure lines of industrial lubrication systems to automatically interlock machinery if auxiliary pump delivery pressures drop below critical operating minimums.
