Performance characteristics of Danfoss AKS32-AKS33 (060G2110) pressure transmitter

AKS32 and AKS33 are pressure sensors that convert pressure measurements into standard electrical signals:
■ AKS32 1 ~ 5Vd.c. or 0 ~ 10Vd.c.
■ AKS33 4 ~ 20mA
The reliable design makes AKS pressure sensors very suitable for a variety of applications, such as:
■ Air conditioning system
■ Refrigeration device
■ Process control

The pressure sensors used in refrigeration systems require high precision. High-performance sensor technology can ensure high-precision pressure measurement and adjustment. This is a very important factor for the precise and economic operation of refrigeration devices.
■ Temperature compensation function of LP and HP pressure sensors specially developed for refrigeration equipment:
LP: -30 ℃ / + 40 ℃ (≤ 16 bar)
HP: 0 ℃ / + 80 ℃ (> 16 bar)
■ Compatibility of all refrigerants, including ammonia, means less inventory and greater flexibility
■ Built-in voltage regulator, AKS pressure sensor can be used on any unregulated power supply within a certain range
■ Efficient moisture-proof design means that the sensor can be installed in a very harsh environment, for example, it can be installed on the suction line wrapped by ice

■ Robust structure protects the sensor from mechanical influences such as shock, vibration and pressure fluctuations. AKS pressure sensor can be installed directly on the device
■ The sensor does not need to be adjusted. Using high-quality sensor technology and instrument sealing mechanism, regardless of the ambient temperature and atmospheric pressure, the factory setting accuracy is not affected by changes in ambient temperature and atmospheric pressure. In air-conditioning and refrigeration applications, it is very important to ensure the control of evaporation pressure
■ EMC protection, comply with EU EMC standard (CE mark)
■ UL certification
■ Polarity protected input
