Abstract
A pressure sensing system includes a hot zone electronics module, a cool zone electronics module and a plurality of conductors that connect the hot zone electronics module to the cool zone electronics module. The hot zone electronics module includes a capacitive pressure sensor and an oscillator that provides an oscillating signal to the capacitive pressure sensor. The hot zone electronics module provides at least one DC sensor signal. The cool zone electronics module converts the at least one DC sensor signal into a pressure value and provides a DC power signal. The plurality of conductors convey the DC power signal to the hot zone electronics module and convey the at least one DC sensor signal to the cool zone electronics module.
