A process variable transmitter for use in an industrial control or monitoring process is provided and includes a housing with a cavity formed therein. The housing includes an integrated terminal block which defines first and second compartments in the cavity. The transmitter further includes a process variable sensor configured to sense a process variable of the industrial process. Measurement circuitry is carried in the first compartment and configured to receive a process variable signal from the process variable sensor and provide an output. An electrical connection is carried on the integrated terminal block in the second compartment and is electrically coupled to the output of the measurement circuitry.

A field device for use in an industrial process includes a housing having a cavity formed therein. A humidity-sealed electronics module has a first compartment formed therein and is positioned in the cavity. The humidity-sealed electronics module includes a seal board. The seal board separates the first compartment of the humidity sealed electronics module from a second compartment in the housing. A first electrical component in the first compartment is mounted to the seal board and a second electrical component in the second compartment is electrically connected to the first electrical component.

A process variable transmitter includes a sensor terminal block having a plurality of sensor line connectors to connect to sensor lines from at least one process variable sensor. The sensor terminal block defines a reception area that in a first instance accepts a removable standard power terminal block and in a second instance accepts a removable transient power terminal block. One of the removable standard power terminal block and the removable transient power terminal block is inserted in the reception area of the sensor terminal block.

A process sensor assembly comprises a hollow protective housing, a temperature sensor, a process transmitter, and a transient protector. The temperature sensor includes a probe extending out of the hollow protective housing to a sensing location, and a top plate movably secured to the hollow protective housing so as to allow travel within the hollow protective housing with vibrations of the probe. The process transmitter is configured to process and transmit sensor signals from the temperature sensor, and is retained on the top plate to move with the temperature sensor within the hollow protective housing. The transient protector is configured to condition power for to the process transmitter, and is anchored to the process transmitter so as to move with the process transmitter within the hollow protective housing.

A temperature sensing system comprises a thermowell, a sensor, and a solid insert. The thermowell extends into a sensing region of a fluid flow. The sensor has a probe housed in the thermowell to sense a temperature in the sensing region. The solid insert is configured to removably support the probe within the thermowell and to provide a thermal contact between the thermowell and the probe.

A process transmitter housing assembly includes a housing and a cover assembly including a cover chassis and a transparent cover piece. The cover chassis includes a cover flange extending inward from a perimeter of the cover chassis. Internal threads of the cover chassis threadedly engage external threads of the housing. The transparent cover piece is mechanically clamped between the cover flange and a surface of the housing nearest the cover flange when the cover chassis is threadedly secured to the housing.

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.

A field device assembly includes a housing body, a first circuitry subassembly mounted to the housing body and positioned at least partially within the housing body, a first cover chassis having a shoulder, mating flame path restricting structures positioned on the first cover chassis and the housing body, a first threaded collar configured to fit about the first cover chassis and to permit rotation relative to the first cover chassis, and a second circuitry subassembly secured to the first cover chassis. The first threaded collar is threadably engaged with the housing body, and includes an engagement structure engaged with the shoulder of the first cover chassis to secure the first cover chassis to the housing body. The second circuitry subassembly includes an electrical connector configured for linear insertion engagement with a mating electrical connector within the housing body to electrically connect the first and second circuitry subassemblies.
