060G2110 Danfoss AKS 33 Heavy Duty Pressure Transmitter

Product Overview

The 060G2110 (060G2110) is a high-reliability pressure transmitter from the Danfoss AKS 33 series, specifically optimized for refrigeration and air conditioning control systems. This industrial-grade sensor converts process pressure into a standardized 4-20 mA current signal, facilitating accurate and stable data transmission over long distances without signal degradation. Engineered to perform in extreme thermal conditions, the 060G2110 operates effectively within a medium temperature range of -40 to 85 deg C. Its sealed gauge reference design ensures that pressure readings remain independent of barometric fluctuations, making it a critical component for maintaining precision in high-capacity chillers, commercial food storage, and industrial cooling racks.

Technical Configuration

The 060G2110 is built for seamless integration into high-performance automation loops:

• Industrial Current Signal: The 4-20 mA output provides high immunity to electrical noise, ensuring consistent performance in mechanical rooms with high electromagnetic interference.

• Sealed Gauge Reference: Utilizing a factory-set internal reference pressure, the sensor delivers accurate relative pressure data regardless of local altitude or atmospheric changes.

• Rugged Electrical Interface: Equipped with an EN 175301-803-A (DIN) angular connector, the unit offers a secure, vibration-resistant connection with an IP65 enclosure rating.

• Thermal Compensation: Includes active electronic compensation for temperatures between 0 and 80 deg C, minimizing thermal drift and ensuring signal linearity across varying seasonal conditions.

Technical FAQs

How does the current signal benefit large-scale HVAC installations?

The current signal of the 060G2110 allows for cable runs of hundreds of meters without voltage drop issues. This is essential in large commercial buildings where the sensor is located on a rooftop condenser while the main PLC cabinet is several floors below.

Can the 060G2110 be used with Ammonia (R717) or CO2 (R744)?

The AKS 33 series is designed for compatibility with most common refrigerants, including HFC, HCFC, and Ammonia. For CO2 applications, ensure the 40 bar overload rating and the specific operating range match your system's transcritical or subcritical pressures.

What is the response time of the AKS 33 sensor?

While optimized for stability, the AKS 33 features a fast internal response time (typically < 4 ms), allowing the controller to react quickly to rapid pressure changes in the suction or discharge lines, which helps in preventing compressor liquid slugging.

Engineering & Installation Guide

• Pulse Protection: In systems with reciprocating compressors or fast-acting solenoid valves, pressure pulsations can cause mechanical fatigue to the diaphragm. It is recommended to install the transmitter using a capillary tube or a pressure snubber to dampen high-frequency pressure spikes.

• Sealing and Maintenance: When attaching the angular connector, verify that the rubber profile gasket is in place. Tighten the central screw to a torque of 0.4 Nm to ensure the IP65 seal is effective against humidity and condensation, which are common in refrigeration environments.

• Grounding and Shielding: To maintain the 0.5% accuracy, utilize a twisted-pair shielded cable. Connect the shield only at the PLC/Controller end to avoid creating ground loops, which can introduce offset errors into the 4-20 mA loop.
