AKS pressure sensor

Danfoss pressure sensor AKS

Danfoss Pressure sensor is to make pressure into electrical signal output. Often the pressure measuring instrument in the electrical measuring instrument called pressure sensor.

◆ Pressure sensor generally by the elastic sensing element and the displacement sensor (or strain gage) composition. The role of the elastic sensing element is to make the measured pressure on a certain area and converted to displacement or strain, and then by the displacement sensor or strain gauge into a certain relationship with the pressure of the electrical signal. Sometimes the function of these two components in one set, such as piezoresistive sensors in the solid-state pressure sensor.

◆ Pressure is the production process and aerospace, aviation, defense industry in the important process parameters, not only need to carry out rapid dynamic measurement, but also the results of the measurement for digital display and record. The automation of large refineries, chemical plants, power plants and steel plants also requires long-distance transmission of pressure parameters and requires the conversion of pressure and other parameters such as temperature, flow, viscosity, etc. into digital signals into the computer. So the pressure sensor is highly valued and the rapid development of a sensor.

◆ The development trend of pressure sensor is to further improve the dynamic response speed, accuracy and reliability, as well as the realization of digital and intelligent.

◆ pressure sensors are commonly used capacitive pressure sensor, variable reluctance pressure sensor, Hall-type pressure sensor, optical fiber pressure sensor, resonant pressure sensor.

 

Alternative Products:

Danfoss AKS3000 series of pressure sensors can be used AKS33 series performance similar to the sensor to replace. Specific models can refer to the company's Web site on the expansion valve-related information or contact the company's technical staff advice.

 

◆ AKS3000 is a sensor in a series of products, with a high intensity of the limited current output, designed to fully meet the requirements of air conditioning and refrigeration

◆ AKS3000 has been proven piezoresistive measurement principle, the measurement method in the Danfoss pressure sensor has been applied for several decades of history

◆ The reference pressure is taken from a sealed pressure chamber so that changes in atmospheric pressure do not affect the accuracy of the measurement. This is necessary to ensure the accuracy of the low voltage measurement

◆ All materials in contact with the refrigerant and the sensor shell are used AISI 316L stainless steel, and all sealed interfaces are laser welding, and no any soft gasket

◆ The output of AKS 3000 is 4 ~ 20mA, with 2m cable, socket or DIN 43650 plug

AKS32 and AKS33 are used to measure the pressure and convert the measured pressure to a standard signal:

◆ AKS32: 1 ~ 5V DC or 0 ~ 10V DC voltage output

◆ AKS33: 4 ~ 20mA current output

AKS-based sensor design makes it perfect for many applications:

◆ air conditioning system

◆ Refrigeration equipment

◆ Process control

◆ Laboratory

Product Features:

High-performance sensors mean high-precision pressure measurement and regulation, which is a very important factor for accurate and economical operation of the refrigeration unit

◆ Temperature compensation for LP (low pressure) and HP (high pressure) pressure sensors developed specifically for refrigeration units:

LP (low pressure): - 30 ℃ ~ +40 ℃ (_16bar)

HP (high pressure): 0 ℃ ~ +80 ℃ (> 16bar)

◆ Compatibility of all refrigerants, including ammonia, means less spare parts storage and greater application flexibility

◆ Built-in voltage regulator, AKS pressure sensor can be used within a certain range of any unadjusted power supply

◆ effective anti-moisture protection so that the sensor can be installed in very harsh environments, such as in the ice-covered suction pipe

Rugged construction The sensors are protected against mechanical effects such as shocks, vibration and pressure fluctuations. AKS type sensors can be mounted directly on field devices

◆ no need to adjust the application of highly developed sensor technology and instrument sealing mechanism, the factory setting accuracy from ambient temperature and atmospheric pressure changes, which in air conditioning and refrigeration applications to ensure that the evaporation pressure control is very important

◆ EMC protection, in line with EU EMC standards (CE mark)

◆ UL certification

◆ Polarity protection input
