TEMPERATURE TRANSMITTER TRANSIENT PROTECTOR

摘要

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.

1. A process sensor assembly comprising:
a hollow protective housing; a temperature sensor that 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 the temperature sensor to travel with respect to the hollow protective housing in response to vibrations of the probe and assembly manufacturing tolerances; a process transmitter configured to process and transmit sensor signals from the temperature sensor, and retained on the top plate to move with the temperature sensor within the hollow protective housing; and a transient protector configured to condition power for the process transmitter, and anchored to the process transmitter to move with the process transmitter within the hollow protective housing.
