DANFOSS AKS 33 060G2107 Pressure Transmitter 4-20 mA

Product Overview

The 060G2107 (060G2107) is a high-performance industrial pressure transmitter from the Danfoss AKS 33 series, specifically engineered for precision monitoring in high-pressure refrigeration and air conditioning systems. This sensor utilizes an advanced piezo-resistive measuring principle to convert fluid pressure into a standardized 4-20 mA current signal, ensuring high noise immunity across long cable distances. The 060G2107 is designed for extreme reliability, featuring a sealed gauge reference and a robust overload pressure rating of up to 55 bar. Optimized for use in commercial refrigeration, heavy-duty chillers, and industrial cooling loops, this transmitter provides the critical data needed for PLC and DCS controllers to maintain system stability, protect compressors from overpressure, and maximize energy efficiency in 24/7 operations.

Technical Configuration

The AKS 33 hardware architecture is built to withstand mechanical stress while maintaining exceptional metrological stability:

• High-Pressure Capability: Engineered for high-side monitoring, this unit supports a maximum overload pressure of 55 bar (798 psi), making it suitable for modern high-pressure refrigerants.

• Sealed Gauge Reference: Referenced to a fixed internal pressure to ensure measurement accuracy remains unaffected by changes in atmospheric pressure or altitude.

• Thermal Compensation: Factory-calibrated within a compensated temperature range of 0 to 80 deg C, significantly reducing thermal zero-shift and maintaining signal accuracy across seasonal temperature fluctuations.

• Industrial Grade Interface: Utilizes the EN 175301-803-A angular connector standard (DIN plug), providing a secure, vibration-resistant electrical termination and an IP65 ingress protection rating.

• Durable Construction: Features a laser-welded stainless steel diaphragm and housing, ensuring broad chemical compatibility with common oils and refrigerants while preventing internal moisture ingress.

Technical Specifications

Technical FAQs

Is the 060G2107 compatible with ammonia (R717) systems?

The AKS 33 series is constructed primarily with stainless steel wetted parts. While it is compatible with a wide range of refrigerants, always verify your specific system's chemical requirements. For dedicated ammonia service, Danfoss often recommends specialized versions of the AKS series to ensure long-term material compatibility.

What is the benefit of the 4-20 mA current output over a voltage output?

The 4-20 mA current loop is the industrial standard for accuracy over distance. Unlike 0-10V signals, a current loop is not affected by voltage drops in long wires and is much more resistant to electromagnetic interference (EMI) from nearby motors or variable frequency drives (VFDs).

Does this transmitter require external calibration upon installation?

No, the 060G2107 is factory-calibrated and temperature-compensated. Once installed and powered within a 4-20 mA loop, it will accurately output the pressure corresponding to its specific range without requiring field calibration.

Engineering & Installation Guide

• Pulsation Dampening: In high-pressure applications near compressor discharge ports, pressure pulsations can cause mechanical fatigue to the sensor diaphragm. It is highly recommended to install a damping orifice or a capillary tube (siphon) between the pipe and the transmitter to buffer these shocks.

• Correct Orientation: To prevent the accumulation of sludge, oil, or debris in the sensor cavity, the 060G2107 should be mounted in a vertical position with the pressure port facing downwards. This allows any heavy contaminants to drain back into the main line via gravity.

• Sealing and Torque: Use a compatible thread sealant (like PTFE tape or specialized refrigeration sealant) on the pressure connection. Apply torque only to the hexagonal base of the transmitter using a properly sized wrench; never use the upper housing or the electrical connector for leverage.
