060G2104 | Danfoss | AKS 33 Pressure Transmitter (060G2104)

Product Overview

The 060G2104 (060G2104) is a high-performance pressure transmitter belonging to the renowned AKS 33 series, specifically engineered for precision monitoring in industrial refrigeration and air conditioning systems. This sensor converts physical pressure into a standard 4 to 20 mA current signal, ensuring reliable data transmission even over long cable runs typical in large-scale facilities like cold storage, food processing plants, and HVAC mechanical rooms. By providing real-time, accurate pressure feedback to a PLC or controller, the 060G2104 is vital for maintaining system efficiency, preventing compressor overload, and reducing unplanned downtime in mission-critical cooling infrastructures.

Technical Configuration

The AKS 33 architecture is built around a robust sealed gauge reference, making it immune to atmospheric pressure fluctuations and ensuring long-term stability. The hardware features a high-grade angular connector (EN 175301-803-A) for secure electrical interfacing and an IP65 rated enclosure that protects the internal electronics against moisture ingress and dust—essential for environments with high humidity or frequent washdowns. The transmitter is temperature-compensated between -30 and 40 deg C, meaning the internal circuitry automatically corrects for thermal expansion or contraction of the sensing element, maintaining a high degree of accuracy across its entire operational range.

Technical Specifications

Technical FAQs

What is the benefit of the 4 to 20 mA current signal in the 060G2104?

The current signal is highly resistant to electrical noise and voltage drops over long distances. Additionally, it provides a "live zero" (4 mA), which allows the control system to immediately distinguish between a zero-pressure reading and a broken wire or sensor failure.

Does this sensor require special protection against moisture?

With an IP65 rating and its specialized angular connector, the AKS 33 is designed to withstand moisture; however, in applications with extreme temperature cycling where condensation is heavy, it is recommended to point the cable entry downwards to prevent water from pooling at the seal.

Is the 060G2104 compatible with ammonia (R717) or other harsh refrigerants?

Yes, the AKS 33 series is specifically designed for refrigeration applications and is compatible with most halogenated refrigerants as well as ammonia, thanks to its high-quality stainless steel wetted parts.

Engineering & Installation Guide

• Pressure Snubbers: In systems where heavy pressure pulsations or "liquid hammer" are expected (e.g., near compressor discharge), it is highly recommended to install a pressure snubber or use a capillary tube to protect the sensing diaphragm from fatigue and premature failure.

• Torque & Sealing: When mounting the transmitter to the process line, ensure use of the correct sealing washer. Do not over-tighten beyond the manufacturer's specification to avoid distorting the internal sensor housing, which can cause zero-point shift.

• Wiring Integrity: Ensure the angular connector is firmly seated and the central screw is tightened. This maintains the IP65 seal. For outdoor installations, use UV-rated cabling to prevent insulation degradation over time.
