Relative pressure transmitter AKS 33

atmosphericmembraneanalog

AKS 32 and AKS 33 are pressure transmitters that measure a pressure and convert the measured value to a standard signal: • 4 – 20 mA for AKS 33 A robust design makes the AKS very suitable for application within a number of fields e.g. • Air conditioning systems • Refrigeration plant • Process control • Laboratories Features Highly developed sensor technology means high pressure regulation accuracy, a very important factor in the precise and energy-economic capacity regulation of refrigeration plants. • Fully digitally compensated, developed specially for refrigeration plants. ◦ LP: -30 – 40 °C (≤ 16 bar) ◦ HP: 0 – 80 °C (> 16 bar) • Compatibility with all refrigerants incl. ammonia means less stock and greater application flexibility • Built-in voltage stabiliser, i.e. the AKS pressure transmitters can be powered from an unregulated voltage supply of any output within given limits • Effective protection against moisture means that the sensor can be mounted in very harsh environments, e.g. in the suction line encapsulated in an ice block • Robust construction gives protection against mechanical influences such as shock, vibration and pressure surge. AKS sensors can be mounted direct on to the plant application • No adjustment necessary. With the highly developed sensor technology and sealed gauge principle, the accuracy of the factory setting is maintained independent of variations in ambient temperature and atmospheric pressure. This is very important when ensuring evaporating pressure control in air conditioning and refrigeration applications • EMC protection according to EU EMC-directive (CE-marked) • UL approved
