DANFOSS AKS 33 060G2114 Pressure Transmitter

Product Overview

The 060G2114 (060G2114) is a heavy-duty pressure transmitter from the Danfoss AKS 33 series, specifically engineered for precision measurement in industrial refrigeration and air conditioning systems. This sensor converts mechanical pressure into a standard 4-20 mA current output signal, ensuring stable data transmission over long distances without signal degradation. The 060G2114 utilizes a sealed gauge pressure reference, making it ideal for high-pressure applications such as CO2 systems, large-scale chillers, and commercial refrigeration plants. By providing accurate feedback to PLC or DCS controllers, this transmitter plays a critical role in optimizing compressor performance, reducing energy consumption, and protecting system components from overpressure conditions in demanding environments like food processing or power generation facilities.

Technical Configuration

The AKS 33 series is built for long-term stability and compatibility with diverse industrial media. The 060G2114 features a robust hardware architecture designed for field reliability:

• Sensing Technology: Employs a piezo-resistive silicon sensor protected by a stainless steel diaphragm, ensuring high resistance against vibration and pressure spikes.

• Signal Processing: The internal electronics provide a linearized 4 to 20 mA output, calibrated within a specialized temperature-compensated range to eliminate drift caused by ambient fluctuations.

• Electrical Interface: Equipped with an EN 175301-803-A angular connector (DIN plug), featuring both male and female components for straightforward field wiring and maintenance.

• Environmental Protection: The laser-welded stainless steel housing achieves an IP65 enclosure rating, providing total protection against dust and low-pressure water jets.

Technical Specifications

Technical FAQs

What is the significance of the "Compensated Temperature Range" for this sensor?

The compensated range (-30 to 40 deg C) is the window where Danfoss guarantees maximum accuracy. While the sensor can operate in ambient conditions up to 85 deg C, keeping the medium within the compensated range ensures the 4-20 mA signal remains precise and free from thermal-induced error.

How do I wire the 4-20 mA output to my controller?

The 060G2114 uses a standard two-wire current loop configuration. Power is typically supplied via the same two wires used for the signal. Consult the EN 175301-803-A pinout to ensure correct polarity, as reversing the current loop may prevent the sensor from functioning.

Is this transmitter compatible with corrosive refrigerants?

The AKS 33 series is constructed with stainless steel wetted parts. It is compatible with all common refrigerants, including high-pressure R744 (CO2). However, always verify that the specific chemical composition of your medium is compatible with AISI 316L or equivalent stainless steel.

Engineering & Installation Guide

• Mounting and Vibration: Although the 060G2114 is vibration-resistant, it should be mounted on a rigid pipe section or bracket to avoid mechanical fatigue. When installed near reciprocating compressors, use a capillary tube or a "pig-tail" siphon to dampen high-frequency pressure pulsations that could shorten the sensor's lifespan.

• Moisture Prevention: To maintain the IP65 rating, ensure the angular connector Gasket is correctly seated and the central screw is tightened to the specified torque. For applications with high humidity or frequent washdowns, orient the connector downwards to prevent water from pooling at the cable entry point.

• Sealing and Torque: Use a proper thread sealant compatible with the refrigerant type. Avoid over-tightening the hexagonal body of the transmitter; use a calibrated wrench on the integral hex nut rather than the sensor housing to prevent internal calibration shifts.
