Abstract
A pressure scanner assembly having at least one replaceable sensor plate, wherein each of the replaceable sensor plates has at least one pressure sensor adapted to transmit a signal substantially indicative of a sensed pressure condition. A memory chip, which stores correction coefficients for each of the pressure sensor to compensate for thermal errors, may be installed on each of the replaceable sensor plates. The signals from the pressure sensors are multiplexed and may be outputted in analog or digital form. The pressure scanner assemblies described herein have sensor plates that can be interchanged with other sensor plates of the same or different pressure range without disrupting the electronic configuration of the pressure scanner assembly or having to recalibrate and/or update the memory chip installed thereon.
