Process variable transmitter with dual compartment housing
First Claim
1. A process variable transmitter for use in an industrial process, comprising:
- a housing having a cavity formed therein which extends between first and second openings;
a process variable sensor configured to sense a process variable of the industrial process;
an electronics carrier assembly comprising an individual component from the housing, in abutting contact with the housing and mounted in the cavity configured to define a first compartment and a second compartment in the cavity, the electronics carrier assembly configured to carry electronics, the electronics carrier assembly including a first cover and a second cover with a cavity formed therebetween;
a seal configured to seal the abutting contact between the electronics carrier assembly and the housing and thereby seal the first compartment from the second compartment;
measurement circuitry carried in the cavity of the electronics carrier assembly and configured to receive a process variable signal from the process variable sensor and provide an output;
an electrical connection carried on the electronics carrier assembly in the second compartment electrically coupled to the output of the measurement circuitry carried in the electronic carrier assembly, the electrical connection providing a transmitter output; and
first and second end caps which seal the first and second openings, respectively, of the housing.

Abstract
A process variable transmitter for use in an industrial control or monitoring process is provided and includes a housing with a cavity formed therein which extends between first and second housing openings. The transmitter further includes a process variable sensor configured to sense a process variable of the industrial process. An electronics carrier assembly is mounted in the cavity and is configured to define a first compartment and a second compartment in the cavity and provide a seal therebetween. Measurement circuitry is carried by the electronics carrier assembly in the first compartment and configured to receive a process variable signal and provide an output. An electrical connection is carried on the electronics carrier assembly in the second compartment and is electrically coupled to the output of the measurement circuitry.
