Customization of process variable transmitter with hermetically sealed electronics

A process variable transmitter, comprising:

• a process variable sensor;
• an electromagnetic interference (EMI) protection circuit coupled to the process variable sensor;
• a hermetic module enclosing the EMI protection circuit, the hermetic module having a first end comprising a feedthrough body and a plurality of feedthrough pins passing through the feedthrough body and hermetically sealed to the feedthrough body, wherein the feedthrough pins are coupled to the EMI protection circuit within the hermetic module and are configurable from outside the hermetic module to connect electronic components of the EMI protection circuit in a configuration that provides transient protection, wherein the plurality of feedthrough pins comprises:
• first and second active conductor feedthrough pins enabling electrical coupling of first and second active electrical conductors inside the hermetic module to first and second active electrical conductors outside the hermetic module;
• an electrical ground feedthrough pin enabling electrical coupling of an electrical ground connector inside the hermetic module to an electrical ground connector outside the hermetic module;
• and
• first and second additional feedthrough pins coupled to different one ones of the circuit electronic components of the EMI protection circuit, wherein each different one of the electronic components is further coupled to the first or second active electrical conductors in the hermetic module.
