Transmetteur de pression AKS 33 - Sortie courant Danfoss 060G2050

Product Overview

The 060G2050 (060G2050) is a high-performance pressure transmitter from the Danfoss AKS 33 series, specifically engineered for refrigeration and air conditioning applications. Optimized for precision and stability, this sensor converts pressure into a standardized 4-20 mA current signal, ensuring reliable long-distance data transmission even in environments with high electromagnetic interference. The 060G2050 features a sealed gauge pressure reference and a robust design capable of withstanding media temperatures from -40 to 85 Celsius. Whether integrated into commercial chillers or industrial cooling racks, this transmitter provides the critical feedback necessary for energy-efficient evaporator and condenser control, significantly reducing the risk of system failures and compressor stress.

Technical Configuration

The 060G2050 is designed for seamless integration into advanced HVAC and refrigeration control loops:

• Sealed Gauge Reference: Provides a stable pressure reference that is isolated from atmospheric pressure fluctuations, ensuring consistent readings in all climate conditions.

• Precision Current Output: The 4-20 mA output signal is highly resistant to voltage drops across long cable runs, making it the preferred choice for large-scale industrial installations.

• Enhanced Thermal Stability: Features an electronically compensated temperature range from 0 to 80 Celsius, maintaining signal accuracy despite varying ambient conditions.

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

Technical Specifications

Technical FAQs

How does the current output benefit refrigeration control?

The 4-20 mA signal produced by the 084G2050 is inherently immune to electrical noise and line resistance. Unlike voltage-based sensors, the current signal remains constant regardless of the cable length, ensuring that the controller receives an exact pressure reading even if the sensor is located far from the electrical panel.

Is the AKS 33 compatible with ammonia (R717)?

Yes, the AKS 33 series is designed to be compatible with most common refrigerants, including ammonia and halogenated refrigerants. Its stainless steel construction ensures resistance to chemical corrosion common in industrial cooling systems.

What is the significance of the "Sealed Gauge" reference?

A sealed gauge reference uses an internal vacuum or set pressure as a baseline. This prevents the sensor from being affected by changes in barometric pressure due to altitude or weather, which is essential for maintaining accuracy in high-pressure refrigeration cycles.

Engineering & Installation Guide

• Vibration and Pulse Protection: To ensure maximum sensor longevity, mount the 060G2050 on a vibration-damped bracket rather than directly on a reciprocating compressor. If the system is prone to liquid hammer or high-frequency pulses, install a capillary tube or a pressure snubber between the pipe and the transmitter.

• Electrical Connection Security: When installing the angular connector (EN 175301-803-A), ensure the rubber gasket is correctly seated before tightening the central screw. This is critical to achieving the IP65 rating and preventing moisture from corroding the electrical pins in humid mechanical rooms.

• Wiring for 4-20 mA Loops: Ensure the power supply is between 9 and 32 VDC. Always use shielded, twisted-pair cabling for signal lines and ground the shield at the controller end only to prevent ground loops that could distort the 0.5% typical accuracy.
