PS80-K1-0248

APPLICATION NOTE AIR CONDITIONING & REFRIGERATION Background AC and refrigeration systems require precise and reliable pressure control to ensure safe, reliable, and efficient operation. As AC and refrigeration equipment utilizes compression and evaporation of refrigerants to produce a cooling effect, therefore it is critical that the refrigerant pressures in these system are managed carefully to ensure the equipment operates properly and will not become unsafe due to excessive pressures. New AC and refrigeration systems also manage pressure with pressure sensors and variable speed compressors to ensure the highest possible energy efficiency. Solution For decades, Sensata has been a leading provider of pressure sensing solutions used in AC and refrigeration systems. The PS80 is a UL listed automatic reset pressure switch that provides electro-mechanical pressure control for both low pressure and high pressure control in refrigerant loops. The PS80 is available in a wide range of pressure settings and configurations which can be used with a wide range of refrigerants. The 2CP5 is a device designed for today’s most efficient AC and Refrigeration equipment that use pressure sensing, electronic controls, and variable speed compressors to precisely manage the refrigerant pressure for lower power consumption, quieter operation and more pressure temperature control. Both the PS80 and 2CP5 are ideal for demanding applications where long-term reliability and accuracy is critical.
