Danfoss 060G2113 Pressure Transmitter AKS 33 Series

Product Overview

The Danfoss 060G2113 (060G2113) is a precision-engineered pressure transmitter specifically developed for the refrigeration and air conditioning industries. As a key component of the AKS 33 series, this transmitter delivers reliable, high-accuracy pressure monitoring in challenging thermal environments. By providing a stable 4-20 mA output signal, the AKS 33 (060G2113) ensures seamless integration with electronic controllers, directly contributing to optimized system energy efficiency and the prevention of catastrophic compressor failures in cooling infrastructure.

Technical Configuration

This transmitter features a ruggedized design capable of maintaining performance across an extreme ambient and media temperature range, spanning from -40 deg C to 85 deg C. The device utilizes a sealed gauge reference, which prevents atmospheric moisture from affecting internal readings, ensuring long-term measurement consistency. The electrical interface employs an industry-standard angular connector (EN 175301-803-A), facilitating secure, IP65-rated connections that are resistant to the vibrations common in refrigeration skids and large-scale HVAC units. Its compact form factor and lightweight construction allow for flexible mounting in dense piping assemblies.

Technical Specifications

FAQs

Is this transmitter suitable for ammonia-based refrigeration systems?

The AKS 33 series is designed to be compatible with most common refrigerants, including fluorinated ones. For ammonia (R717) applications, please confirm the wetted parts compatibility in the official documentation, as specific versions may be required for chemical resistance.

What does the sealed gauge pressure reference signify?

Unlike a vented gauge reference, the sealed gauge is factory-calibrated to a reference pressure inside the sensor. This eliminates the risk of condensation or corrosive gases entering the sensor through a vent tube, making it ideal for high-humidity environments.

Can the transmitter be mounted in any orientation?

Yes, the AKS 33 can be mounted in any orientation. However, it is recommended to avoid mounting it where oil or sediment can collect at the pressure port, as this may lead to signal drift over time.

How do I troubleshoot an erratic output signal?

Erratic signals are often caused by poor grounding or EMI interference. Verify that the angular connector is firmly seated and that the cable shield is grounded at the controller side only, avoiding ground loops that often occur in distributed control systems.

Installation Guidelines and Best Practices

• Vibration Management: While designed for HVAC equipment, excessive localized vibration can cause accelerated wear on the internal sensor diaphragm. Where possible, mount the transmitter on a rigid support or use a pressure-rated capillary loop to decouple it from high-frequency compressor vibration.
• Connector Integrity: The IP65 rating is dependent on the proper seating of the gasket in the angular connector. When tightening the central screw, ensure it is secure but do not over-torque, as this can crack the connector housing or deform the sealing gasket.
• Thermal Protection: Although the transmitter is rated for 85 deg C, avoid mounting the device directly on hot discharge lines. If the media temperature approaches the upper limit, use a standoff or a pressure-rated flexible tube to dissipate heat and protect the electronics from long-term thermal fatigue.
