Danfoss 084N0003 Sensor

The Danfoss 084N0003 AKS 11 Sensor is a high-precision PT1000 temperature sensor engineered for demanding commercial refrigeration and HVAC systems. As a platinum resistance element, this sensor provides superior accuracy across a wide temperature range of -40°F to 212°F (-40°C to 100°C), making it the standard for evaporator coil temperature monitoring, suction line superheat calculations, and HACCP-compliant food safety logging. This specific model features a 11.5-foot (3.5m) PVC cable, providing ample lead length for reaching controller inputs on display cases or walk-in coolers.

Built as a Danfoss ADAP-KOOL compatible sensor, the 084N0003 integrates seamlessly with ERC, AK, and MCX series controllers. Its IP67 rated enclosure ensures reliable operation in high-humidity environments where moisture ingress typically causes thermistor failure. The sensor design includes a rounded surface for optimized thermal contact with copper tubing, ensuring a rapid 10-second time constant for precise HVACR system diagnostics. For technicians, the 1000-ohm resistance at 32°F (0°C) allows for quick field verification using a standard multimeter, ensuring the RTD sensor remains within its Class B tolerance specifications.

• Platinum PT1000 Precision: Delivers higher stability and lower drift compared to standard NTC thermistors, ensuring long-term HVACR sensor accuracy.
• Rugged IP67 Construction: Hermetically sealed sensor head prevents internal corrosion from condensation in low-temp refrigeration applications.
• Industry-Standard Resistance: 1000 Ohm nominal resistance at 0°C simplifies Danfoss controller integration and field troubleshooting.
• Extended Lead Prep: The 11.5-foot 2-wire PVC cable allows for clean routing to the input terminal board without the need for additional splices.
• Universal Cooling Compatibility: Engineered for use in supermarket refrigeration systems, air conditioning units, and heating loops.

• Can this sensor be used for defrost termination? Yes, the rugged housing and temperature range make the AKS 11 ideal for monitoring coil temperatures to trigger or terminate defrost cycles.
• Is the 084N0003 compatible with non-Danfoss controllers? As long as the controller is configured for a PT1000 RTD input, this sensor will provide accurate resistance feedback.
• How do I verify the sensor is functioning correctly? Set your multimeter to Ohms; at 32°F (0°C), you should see a reading of 1000 Ohms. The resistance should increase as the temperature rises.
