DANFOSS AKS 33 060G2112 Pressure Transmitter 4-20 mA

Product Overview

The 060G2112 (060G2112) is a precision-engineered pressure transmitter within the Danfoss AKS 33 series, specifically designed for industrial refrigeration and air conditioning applications. This sensor converts measured pressure into a robust 4-20 mA current output, ensuring high signal integrity over long cable runs in electrically noisy environments. Optimized for reliability, the 060G2112 features a sealed gauge pressure reference and is capable of sustaining overload pressures up to 33 bar. It is a critical component in systems requiring accurate head pressure control or suction pressure monitoring, such as large-scale chillers and commercial cold storage. By providing real-time data to PLC or DCS systems, this transmitter helps maintain optimal system efficiency and prevents critical equipment failures due to overpressure conditions.

Technical Configuration

The AKS 33 hardware platform is built to withstand the rigors of industrial mechanical rooms while maintaining high metrological performance:

• Sensing Technology: Utilizes a highly stable piezo-resistive sensor coupled with a stainless steel diaphragm, providing excellent resistance to vibrations and thermal cycling.

• Specialized Compensation: The internal circuitry is factory-calibrated within a compensated temperature range of -30 to 40 deg C, specifically targeting refrigeration cycles to eliminate measurement drift caused by cold-start conditions or ambient shifts.

• Electrical Interface: Features an EN 175301-803-A angular connector (DIN plug), providing a secure, IP65-rated connection that simplifies field installation and sensor replacement.

• Rugged Construction: The laser-welded stainless steel body ensures compatibility with common refrigerants and prevents internal moisture ingress, which is essential for low-temperature operating environments.

Technical FAQs

How does the 4-20 mA current signal benefit long-distance wiring?

The current signal used by the 060G2112 is inherently resistant to electromagnetic interference (EMI) and voltage drops across long cables. Unlike voltage signals, the 4-20 mA loop maintains its accuracy over several hundred meters, which is vital for large industrial facilities where the transmitter and controller are far apart.

What medium can be measured with the 060G2112?

This transmitter is compatible with a wide range of media including air, water, and common refrigerants (including ammonia in specific configurations). Its stainless steel construction ensures durability; however, always confirm chemical compatibility for non-standard industrial fluids.

Is the sensor protected against pressure spikes?

While the 060G2112 is rated for an overload pressure of 33 bar, frequent high-frequency pressure pulsations can cause mechanical fatigue. It is recommended to use a damping orifice if the sensor is located near a compressor discharge port.

Engineering & Installation Guide

• Vibration Mitigation: To ensure long-term stability, avoid mounting the transmitter directly onto high-vibration surfaces like compressor heads. Use a short length of capillary tubing to remote-mount the sensor on a stable bracket, which also acts as a thermal buffer for extremely hot or cold media.

• Moisture Management: To prevent condensate from entering the electrical housing, the cable should always enter the angular connector from below. Create a "drip loop" in the cable so that moisture gravity-drains away from the transmitter seal.

• Torque and Sealing: When installing the transmitter into a pressure port, apply sealant only to the threads and not the front face of the sensor. Tighten the unit using the integral hex nut; never apply torque to the upper housing or the electrical connector to avoid damaging the internal electronics.
