Pneumatic-digital converter system and method

A chassis for receiving a plurality pressure monitor lines and a plurality of module assemblies, each said module assembly having a pneumatic module connector, an electrical module connector, and an electronic circuit means interconnected between said pneumatic module connector and said electrical module connector, said chassis comprising:

• a face plate;
• a plurality of pneumatic connectors carried on said face plate, each providing pneumatic interconnection between a different one of said pneumatic module connectors and a corresponding different one of said pressure monitor lines;
• a plurality of electrical connectors carried on said face plate, each providing electrical connection to a different corresponding one of said electronic circuit means;
• and
• a plurality of bus lines carried on said face plate electrically interconnecting different ones of said electronic circuit means when said electrical module connectors of said module assemblies are inserted in respective different ones of said plurality of electrical connectors.

A module assembly for use with a pneumatic to electrical converter system chassis, comprising:

• a printed circuit board having an electrical connector for connection to said chassis;
• a back support interconnected to said printed circuit board and lying in a plane intersecting said printed circuit board;
• and
• a float-mounted pneumatic connector carried by said back support for connection to said chassis.

A pressure monitoring system for monitoring pressures on a plurality of pressure monitor lines, comprising:

• a chassis comprising
• a face plate;
• a plurality of pneumatic chassis connectors carried on said face plate, each interconnectable to a different one of said pressure monitor lines;
• a plurality of electrical chassis connectors carried on said face plate;
• and
• a bus line conductor means for electrically interconnecting said plurality of electrical chassis connectors;
• and
• a plurality of module assemblies, each comprising
• a printed circuit board having an electrical connector disposed in one of said plurality of electrical chassis connectors;
• a pneumatic module connector carried by said printed circuit board and disposed in one of said plurality of pneumatic chassis connectors;
• and
• electronic circuit means interconnected between said printed circuit board electrical connector and said pneumatic module connector.
