Abstract: A process transmitter includes a transmitter housing and a liquid detector coupled to the transmitter housing. The liquid detector includes a temperature sensor configured to generate signals indicative of a presence of liquid within the transmitter housing. The process transmitter also includes a controller coupled to the liquid detector configured to receive the generated signals, determine the presence of liquid within the transmitter housing based on the received signals, and generate an output indicative of the determined presence of liquid within the transmitter housing.
