Due to its excellent resistance against the most commonly used refrigerants, the 1PT series pressure transmitter with integrated ceramic thick-film sensor is optimally suited for refrigeration and HVAC applications. The 1PT series unites innovative design and highest demands on quality. The instrument has successfully passed a test process that is specially adapted to the harsh requirements of the refrigeration and HVAC market. With its highly flexible product and manufacturing concept, the 1PT series transmitter is convincing thanks to its high availability, even in large quantities, and that at an attractive price/performance ratio.
The 1PT series transmitter is widely used in refrigeration and HVAC, subcooling and superheat calculations, discharge and suction pressure monitoring, compressor staging and unloading, remote systems diagnostics and trending, electronic expansion valve control, compressor oil pressure monitoring, condenser fan control.
