Transmetteur de pression Danfoss AKS 33 060G2047

Product Overview

The 060G2047 (060G2047) is a high-precision AKS 33 series pressure transmitter engineered by Danfoss for demanding industrial refrigeration and air conditioning applications. Optimized to convert measured pressure into a professional-grade 4-20 mA current signal, this sensor is a critical component for maintaining system stability in environments ranging from commercial cooling to heavy-duty process automation. The 060G2047 features advanced temperature compensation technology, ensuring linear and accurate data acquisition even when the medium temperature fluctuates between -40 and 85 deg C. By providing real-time, high-resolution feedback to PLC or DCS controllers, this transmitter plays a vital role in optimizing compressor performance and protecting the system against overpressure events.

Technical Configuration

The AKS 33 platform is built around a "Sealed Gauge" pressure reference, making it immune to variations in atmospheric pressure and ideal for high-pressure refrigeration circuits. This unit utilizes an angular connector standard (EN 175301-803-A), providing a secure, vibration-resistant electrical interface with an IP65 enclosure rating. The hardware is designed for maximum durability, capable of sustaining overload pressures up to 33 bar (479 psi) without permanent deformation or calibration drift. Internally, the transmitter is laser-calibrated within a specific compensated temperature range of -30 to 40 deg C, which minimizes thermal zero shift and span errors, ensuring the 4-20 mA output remains a "source of truth" for the control logic in extreme climates.

Technical FAQs

What is the benefit of the 4-20 mA current signal in the 060G2047?

The current-loop output is highly resistant to electromagnetic interference (EMI) and signal attenuation over long cable distances. Unlike voltage signals, the 4-20 mA output ensures that the controller receives accurate pressure data even if the sensor is located far from the control cabinet in large-scale industrial plants.

Does the 060G2047 require frequent recalibration?

No. The AKS 33 series is designed for "fit and forget" operation. Its sealed gauge design and laser-welded stainless steel construction provide excellent long-term stability, reducing the maintenance burden and the need for field calibration in standard operating conditions.

Can this transmitter be used with CO2 or ammonia refrigerants?

The 060G2047 is compatible with most halogenated refrigerants. However, for specific corrosive media like ammonia (R717) or high-pressure CO2 (R744) applications, it is essential to verify that the internal seal and wetted materials match the chemical compatibility of the refrigerant used.

Engineering & Installation Guide

• Condensation Prevention: When installing the transmitter on suction lines or in low-temperature evaporators, mount the unit in a position where moisture cannot accumulate inside the angular connector. Orient the cable entry downwards to allow any condensation to drain away, preserving the IP65 seal integrity.

• Pressure Pulsation Shielding: To protect the internal sensing element from hydraulic shock or rapid pressure pulses (common near reciprocating compressors), it is highly recommended to install a damping orifice or a capillary tube between the pressure port and the transmitter.

• Electrical Grounding: Ensure the shield of the signal cable is grounded at the controller side to eliminate potential ground loops. When mating the male and female angular connectors, verify the gasket is seated correctly to prevent ingress of oil or moisture, which could cause signal drift.
