Field serviceable, small form-factor pressure scanner

A field serviceable, compact, multi-channel pressure scanner assembly, comprising:

• a housing configured to house pressure sensors and a data acquisition assembly, the housing comprising:
• a mounting plate comprising a plurality of through-hole bores extending from a front side to a back side of the mounting plate and configured for mating with corresponding pressure sensors;
• and
• two or more field-replaceable pressure sensors mounted to the mounting plate, each pressure sensor comprising one or more sensor ports, each of the one or more sensor port in communication with corresponding through-hole bores in the mounting plate;
• and
• a multi-channel data acquisition system configured to receive pressure signals from the two or more field-replaceable pressure sensors.

A method of replacing a field-replaceable data acquisition module in a compact, multi-channel pressure scanner assembly during operation, the method comprising:

• unplugging, from a connector of at least one pressure sensor, a communication cable electrically connected to a first data acquisition module of the scanner assembly;
• removing the first data acquisition module from a mounting plate of the scanner assembly;
• installing and securing a second data acquisition module to the mounting plate in a position previously occupied by the first data acquisition module;
• and
• plugging the communication cable into a connector of the second data acquisition module.
