1. A temperature transmitter comprising:
- a cylindrical dual-compartment housing having a first compartment and a second compartment, the first compartment being configured to receive field wiring at a terminal block through at least one conduit, the first and second compartments being separated except for an electrical feedthrough therebetween;
a head-mount temperature transmitter electronics module used to measure a process temperature disposed in the second compartment and being operably coupled to the terminal block in the first compartment; and
an adapter module disposed in the second compartment which electrically connects the head-mount temperature transmitter electronics module to the terminal block including at least one alignment feature configured to maintain the head mount temperature transmitter in a unique rotational position.

Abstract
A temperature transmitter includes a dual-compartment housing and a head-mount temperature transmitter electronics module. The dual-compartment housing has a first compartment and a second compartment. The first compartment is configured to receive field wiring at a terminal block through at least one conduit. The first and second compartments are separated except for an electrical feedthrough therebetween. A head-mount temperature transmitter electronics module is disposed in the second compartment and is operably coupled to the terminal block in the first compartment.
