초록 ▼

A process variable transmitter for use in an industrial process includes a housing having a cavity formed therein. The housing has a barrier which divides the cavity into first and second cavities. Preferably, measurement circuitry in the first cavity is configured to measure a process variable of the industrial process. A terminal block assembly is positioned in the second cavity. The terminal block assembly forms a seal with the housing thereby forming a third cavity between the barrier and a circuit board of the terminal block assembly.

The process variable transmitter of claim 8 wherein the connectors are mounted to the barrier. 17. The process variable transmitter of claim 8 wherein the connectors are mounted to the terminal block assembly. 18. The process variable transmitter of claim 17 wherein the circuit board includes a temperature sensor for use in compensating measurements. 19. The process variable transmitter of claim 1 wherein the barrier includes an opening and the terminal block is sealed against the opening. 20. The process variable transmitter of claim 1 wherein the circuit board carries a temperature sensor. 21. The process variable transmitter of claim 1 wherein the circuit board carries communication circuitry. 22. The process variable transmitter of claim 2 wherein the shroud member is soldered to the circuit board. 23. The process variable transmitter of claim 1 including at least one electrical connection between the circuit board and the measurement circuitry. 24. The process variable transmitter of claim 23 wherein the at least one electrical connection extends through the barrier. 25. The process variable transmitter of claim 1 wherein the terminal block includes an alignment feature for alignment with the housing. 26. The process variable transmitter of claim 1 including first and second end caps configured to enclose the respective first and second cavities of the housing. 27. The process variable transmitter of claim 1 including a process variable sensor coupled to the measurement circuitry for use in measuring the process variable. 28. The process variable transmitter of claim 1 wherein the circuit board carries temperature measurement circuitry configured to couple to an external temperature sensor.
