The newer design EC155 sample cell (serial numbers 2000 and greater) uses an absolute pressure
sensor to measure sample cell pressure, but the pressure differential relative to ambient pressure is
reported. This provides consistency with the older design outputs and is useful in monitoring
potential flow constrictions in the intake.
