The S05-1A05-02D is a differential pressure sensor manufactured by Sensata Technologies. This device is able to measure the difference in pressure between two different points and translate that pressure into an electrical output signal. It is a high accuracy, wide temperature range differential pressure transducer, designed to measure pressure differences from 0 to 5psi (0-35kPa). It features high accuracy and a long life, making it suitable for a wide range of industrial and commercial applications, including HVAC and refrigeration systems.
