Its robust metal construction stands up to the intense thermal cycling of modern HVAC heating systems

or incorrect gas pressure causing the unit to fire over its rated BTU capacity

it prevents moisture accumulation that leads to premature HVAC corrosion and bearing failure

ensure your subplate and mounting screws are intact

it functions as a critical vent limit switch that interrupts gas flow if hazardous venting conditions or overheating are detected

Danfoss 084N0027 Sensor Its robust metal construction standsThe Danfoss 084N0027 AKS 11 is a high precision Pt 1000 temperature sensor designed for demanding commercial refrigeration and HVACR applications. Engineered as a resistance temperature detector (RTD), this sensor features a 1000 Ohm resistance at 0C and complies with EN 60751, Class B tolerance standards for consistent signal accuracy. The sensor head is specifically curved to maximize surface contact with copper suction lines and discharge pipes,
