Differential pressure sensor is used to measure the pressure difference between two pressure terminals. It senses and compares the pressure at both input ports, converting the pressure difference into a standard electrical signal (such as voltage, current, or a digital signal) as an output.
Digital differential pressure sensor integrates the differential pressure sensing element, ADC, temperature compensation, and digital interface into a single chip, directly outputting a digital signal without the need for external amplifier circuits and A/D converters.
