Abstract: A process variable transmitter includes a process variable sensor, and an electromagnetic interference (EMI) protection circuit coupled to the process variable sensor. The process variable transmitter also includes a hermetic module enclosing the EMI protection circuit, and electrical connectors coupled to the EMI protection circuit within the hermetic module. The electrical connectors are configurable from outside the hermetic module to connect electronic components of the EMI protection circuit in a configuration that provides transient protection.
