Abstract
in-situ pressure sensor bias determination apparatus comprises a measurement pressure sensor (400), a reference pressure sensor (402), an electronically controllable pressure adjustment device (406), and a fluid conduit network (410) having an ambient access port (412) wherein the reference pressure sensor is selectively fluidly coupleable to the fluid conduit network. The measurement pressure sensor (400) has a greater operating pressure range than the reference pressure sensor (402). The measurement pressure sensor (400), the reference pressure sensor (402) and the pressure adjustment device (406) are sealingly coupled to the fluid conduit network (410) so as to define a volume that is open only at the ambient access port (412). An ambient isolation device (420) is arranged to isolate selectively the ambient access port (412) from the measurement pressure sensor (400), the reference pressure sensor (402) and the pressure adjustment device (406), thereby closing the open volume.
