Product Overview

The Danfoss 060G2051 (AKS 33) pressure transmitter is a precision-engineered sensor designed for high-reliability monitoring in industrial refrigeration and air conditioning systems. The 060G2051 utilizes advanced piezoresistive technology to provide accurate signal output, serving as a critical component in process control loops to monitor refrigerant pressures. By delivering a stable 4 to 20 mA signal, this transmitter minimizes measurement drift, ensuring optimal system performance and reducing the likelihood of catastrophic equipment failure in critical cooling infrastructure.

Technical Configuration

The AKS 33 series is designed to handle demanding physical and chemical stresses inherent in industrial process environments:

• Sensing Technology: Utilizes a laser-calibrated piezoresistive sensing element for high linearity and thermal stability.
• Output Protocol: Provides a standard 4 to 20 mA analog output, offering high noise immunity over long cable runs.
• Connection Standard: Features an industry-standard EN 175301-803-A angular connector, facilitating easy integration and field maintenance.
• Media Compatibility: Optimized for a wide range of refrigerants (including ammonia and HFCs) and capable of withstanding extreme ambient conditions ranging from -40 to 85 Celsius.
• Pressure Reference: Configured as a sealed gauge transmitter, ensuring internal integrity even when exposed to fluctuating external atmospheric pressures.

Technical Specifications

FAQs

Is the AKS 33 transmitter compatible with ammonia (R717) systems?

Yes, the AKS 33 is specifically designed for high compatibility with various refrigerants, including ammonia, due to its stainless steel wetted parts.

What is the significance of the 4-20 mA output in this transmitter?

The 4-20 mA current loop is the industrial standard for transmitting sensor data over long distances because it is highly resistant to electromagnetic interference and allows for simple cable break detection.

Does the 060G2051 require calibration after installation?

No, the device is factory-calibrated for high accuracy. However, periodic verification against a master gauge is recommended in safety-critical applications.

Installation and Operational Guidelines

• Pressure Pulsations: In systems with high pressure transients or rapid compressor cycling, install a pulsation damper or a restrictor orifice at the pressure port to prevent mechanical fatigue of the sensor diaphragm.
• Electrical Installation: Use shielded cable for the 4-20 mA signal loop. Connect the cable shield to the ground terminal only at the controller side to avoid creating ground loops, which can induce measurement noise.
• Seal Integrity: The IP65 rating relies on the correct installation of the angular connector gasket. Ensure the gasket is seated properly and the central screw is tightened to the specified torque to prevent moisture ingress.
• Orientation: While the sensor can be mounted in any orientation, it is recommended to install it in a vertical position with the pressure connection pointing downward to prevent accumulation of debris or oil in the sensing chamber.
