DANFOSS AKS 33 060G2102 Pressure Transmitter 4-20 mA

Product Overview

The 060G2102 (060G2102) is a high-accuracy industrial pressure transmitter from the Danfoss AKS 33 series, specifically designed for demand-driven refrigeration and air conditioning systems. This sensor utilizes advanced piezo-resistive technology to convert fluid pressure into a standardized 4-20 mA current signal, ensuring high noise immunity even in electrically "noisy" industrial environments. The 060G2102 is built with a sealed gauge reference and is capable of handling overload pressures up to 40 bar. Engineered for critical cooling loops in power plants, cold storage facilities, and food processing lines, this transmitter provides the precise feedback necessary for PLC-based compressor control and head pressure regulation, effectively extending equipment life and optimizing energy efficiency.

Technical Configuration

The AKS 33 series is optimized for stability and long-term reliability in harsh mechanical environments. The 060G2102 incorporates several key architectural features:

• Pressure Sensing Element: Features a robust stainless steel diaphragm that is laser-welded to the sensor housing, providing a leak-proof seal and excellent resistance to pressure pulsations.

• Thermal Compensation: Unlike standard industrial sensors, the 060G2102 is factory-calibrated within a specific compensated temperature range of 0 to 80 deg C to minimize thermal zero-shift and sensitivity errors.

• Electrical Interface: Utilizes a standard EN 175301-803-A angular connector (often referred to as a DIN plug), which facilitates rapid field replacement and secure electrical termination.

• Signal Output: The two-wire 4 to 20 mA output is compatible with the majority of industrial controllers, allowing for cable runs of several hundred meters without signal loss.

Technical Specifications

Technical FAQs

How does the "Sealed Gauge" reference differ from a standard gauge sensor?

A sealed gauge reference, like that in the 060G2102, is referenced to a fixed internal pressure (typically 1 bar) rather than local atmospheric pressure. This makes it ideal for high-pressure applications and ensures the sensor remains unaffected by changes in altitude or atmospheric weather conditions, which is critical for precision refrigeration control.

What is the maximum operating temperature for the medium being measured?

The sensor can safely measure media with temperatures ranging from -40 to 85 deg C. However, for maximum signal accuracy, it is recommended to maintain the medium temperature within the compensated range of 0 to 80 deg C.

Is the angular connector included with the transmitter?

Yes, the 060G2102 follows the Male and Female specification, meaning both the transmitter base and the corresponding DIN plug (Angular Connector) are typically provided to ensure a complete IP65-rated electrical assembly.

Engineering & Installation Guide

• Mounting Orientation: To prevent the accumulation of oil or debris within the sensor cavity, the 060G2102 should ideally be mounted in a vertical position with the pressure connection facing downwards. If installed on a horizontal pipe, use a mounting tee that allows the sensor to sit at the top or side of the pipe.

• Wiring Precautions: Use shielded twisted-pair cable for the 4-20 mA loop, especially in environments with variable frequency drives (VFDs). The shield should be grounded only at the controller side to prevent ground loops that could introduce signal offsets.

• Pressure Pulsation Protection: In systems with high-frequency pressure spikes (e.g., near high-speed reciprocating compressors), it is highly recommended to install a damping orifice or a capillary tube to protect the internal diaphragm from fatigue and premature failure.
