Danfoss 060G2101 AKS33 Pressure Transmitter

The Danfoss 060G2101 AKS33 Pressure Transmitter is a high-precision sensor engineered for high-performance refrigeration and air conditioning systems. This model is specifically calibrated for a pressure range of -1 to 12 bar, providing a linear 4-20 mA output signal that ensures reliable data transmission even over long distances. Built with a robust stainless steel body, the AKS33 utilizes high-grade piezoresistive technology and temperature compensation to maintain accuracy within ±0.3% FS, even under fluctuating ambient conditions. The 1/4 inch NPT pressure connection and DIN 43650 plug (EN 175301-803) interface allow for straightforward integration into existing PLC or controller loops. Designed to handle all HFC/HCFC refrigerants and ammonia (NH3) applications, this transmitter is built for long-term stability in harsh mechanical environments where vibration and moisture ingress are constant concerns.

Key Technical Benefits

• Precision Signal Response: The 4-20 mA current output provides high noise immunity for accurate monitoring in industrial electrical environments.
• Corrosion Resistance: Laser-welded stainless steel construction prevents refrigerant leaks and protects internal electronics from moisture.
• Refrigerant Compatibility: Suitable for all common refrigerants, including subcritical CO2 and ammonia systems.
• Built-in EMI Protection: Integrated circuitry protects the sensor against electromagnetic interference and transient voltage spikes.
• Temperature Compensation: Factory-calibrated for high thermal stability across a wide operating range, reducing reading drift in varied climates.

Common Technical Questions

How do I wire the AKS33 to a standard PLC?
The AKS33 is a two-wire transmitter. Terminal 1 on the DIN plug typically connects to the 24V DC supply, while Terminal 2 returns the 4-20 mA signal to your controller's analog input.

Can this pressure transmitter be used on the high side of an R410A system?
No, the 060G2101 model is rated for -1 to 12 bar (approx. 174 psi), making it suitable for low-side suction monitoring. For high-side R410A monitoring, a higher pressure range transmitter is required.

What happens if the pressure exceeds the 12 bar rating?
The AKS33 has a high burst pressure capability, but operating above the rated 12 bar measurement range will result in an "out of range" signal clip at 20 mA and may lead to calibration shift if the overpressure limit is exceeded.
