Abstract
A field device system for use in an industrial process includes a field device configured to couple to the industrial process and monitor or control the industrial process. The field device provides a temperature control signal output related to a temperature of the field device. A heater coupled to the field device heats the field device in response to the temperature control signal.

18. A method reducing accumulation of process material on a field device in an industrial process, comprising:
-
sensing an internal temperature of the field device;
providing a temperature control signal output related to the sensed temperature;
coupling the temperature control signal output to a heater which is thermally coupled to the field device; and
responsively heating the field device with the heater as a function upon the temperature control signal output. - View Dependent Claims (19, 20, 21, 22, 23, 24)
