Patent Images
1. A field device for use in an industrial process, comprising:
- a housing having a cavity formed therein;
a humidity-sealed electronics module having a first compartment formed therein, the humidity-sealed electronics module positioned in the cavity and including a seal board, wherein the seal board separates the first compartment of the humidity sealed electronics module from a second compartment in the housing and forms a seal therebetween;
a first electrical component in the first compartment mounted to the seal board; and
a second electrical component in the second compartment electrically connected to the first electrical component;
wherein the humidity-sealed electronics module divides the housing into the second compartment and a third compartment and the first compartment is sealed with respect to the second and third compartments and the second compartment is further sealed with respect to the third compartment;
wherein the humidity-sealed electronics module includes a side wall and the seal board is sealed to the sidewall; and
wherein the humidity-sealed electronics module includes a second seal board sealed to the side wall opposite the seal board.
