Abstract:
A process variable transmitter (100) for use in an industrial process includes a housing (102) having a cavity formed therein. The housing has a barrier (120) which divides the cavity into first (104) and second (106) cavities. Preferably, measurement circuitry (110) in the first cavity (104) is configured to measure a process variable of the industrial process. A terminal block assembly (108) is positioned in the second cavity (106). The terminal block assembly (108) forms a seal with the housing (102) thereby forming a third cavity (108) between the barrier and a circuit board of the terminal block assembly.
