Danfoss AKS 21W Immersion Temperature Sensor – 084N2017
The Danfoss AKS 21W 084N2017 is a Pt1000 immersion temperature sensor designed for accurate temperature measurement in refrigeration, air conditioning and heating applications.
Featuring a wide operating range, stainless-steel immersion sensor construction and a fire-resistant silicone cable, the AKS 21W is designed for reliable temperature sensing across demanding HVACR applications.
AKS 21W 084N2017 Pt1000 Immersion Sensor −70°C to +180°C🌡️ Accurate Immersion Temperature Measurement
The Danfoss AKS 21 series is a range of Pt1000 temperature sensors developed for refrigeration, air-conditioning and heating systems.
Model AKS 21W 084N2017 is the immersion version, allowing the sensor to measure the temperature of the medium through its sensor pocket rather than simply measuring the surface or surrounding air temperature.
The sensing element has a nominal resistance of 1000 Ω at 0°C and is factory calibrated to meet EN 60751 Class B tolerance requirements.
