060G1323 Transmetteur de pression pour réfrigération Danfoss AKS 3000

Product Overview

The 060G1323 (060G1323) is a specialized pressure transmitter from the Danfoss AKS 3000 series, specifically optimized for high-precision measurement in refrigeration and air conditioning systems. Covering a pressure range from -1 to 12 bar, this sensor is engineered to withstand the unique chemical and thermal stresses of refrigerant cycles. By providing a 4 - 20 mA output signal, the 060G1323 enables real-time monitoring of suction and discharge pressures. Its robust design is certified for ATEX and cUR environments, ensuring safety and durability in volatile industrial settings. Implementing this transmitter in chiller units or commercial cooling plants significantly enhances system stability and energy efficiency while protecting compressors from operating outside safe pressure limits.

Technical Configuration

The 060G1323 is built on a high-reliability platform with the following core architectural features:

• Pressure Range Efficiency: Optimized for -1 to 12 bar, making it ideal for low-to-medium pressure refrigerants and vacuum monitoring.

• Signal Integrity: Features signal clipping (High: 22.4 mA, Low: 3.6 mA) to prevent PLC input errors during sensor over-range or fault conditions.

• Electrical Robustness: Supports a wide supply voltage from 9 to 32 VDC, allowing for integration into various control system architectures.

• Mechanical Interface: Utilizes a specialized 7/16-20 UNF (1/4 in Flare) connection, a standard in refrigeration technology to ensure leak-proof seals under high vibration.

• Rapid Response: A maximum response time of 4 ms ensures that fast-acting pressure transients are captured and processed by the controller immediately.

Technical Specifications

Technical FAQs

Is the 060G1323 compatible with Ammonia (R717) or CO2 (R744)?

The AKS 3000 series is generally compatible with HCFC, HFC, and non-flammable refrigerants. However, for Ammonia applications, it is standard practice to verify that the wetted parts (AISI 316L) meet your specific concentration requirements, or consider the Danfoss AKS 33 series.

What is the benefit of the "Compensated Temperature Range"?

Between -30 and 40 deg C, the 060G1323 employs internal temperature compensation to ensure that thermal expansion of the sensor components does not affect the accuracy of the 4 - 20 mA signal, maintaining the 0.5 percent non-linearity rating.

What does the 3.6 mA Low Clipping level signify?

The clipping level ensures the signal never drops below a certain point during normal operation. If your PLC detects a signal below 3.6 mA, it serves as a diagnostic indicator of a wire break or a total sensor failure rather than a low-pressure reading.

Engineering & Installation Guide

Flare Connection and Leak Prevention:

When mounting the 1/4 in Flare (7/16-20 UNF) connection, do not over-tighten. Excessive torque can deform the flare seat, leading to refrigerant leaks. It is recommended to use a backup wrench on the transmitter body while tightening the flare nut to avoid putting rotational stress on the transmitter's internal housing and electronics.

ATEX Compliance and Grounding:

As this unit carries ATEX approval, ensure that the installation complies with local hazardous area regulations. The transmitter must be integrated into an intrinsically safe circuit if used in Zone 0 or Zone 1 environments. Ensure the IP65 rating is maintained by using the correct cable diameter for the Pg 9 plug and tightening the gland nut until the cable is securely gripped and sealed.
