Abstract
An integrated heater and controller assembly for monitoring and controlling the heating of a process in a reservoir is disclosed. The assembly includes a heater, a coupling adapter, a control unit, and a temperature sensor. The heater attaches to the reservoir and has a heating element extending into the process. The coupling adapter includes a first tubular portion and a second tubular portion. The first tubular portion attaches to the heater. The second tubular portion attaches to the control unit. The first tubular portion is rotatably attached to the second tubular portion. Wires from the control unit communicate through a pathway in the first and second tubular portions and connect to the heater. The control unit has control circuitry to control the power supplied through the wires to the heater. The heater may also have a thermowell that extends into the process. A thermowell adapter may be used to mount the temperature sensor inside the thermowell to measure and report the temperature of the process to the control unit.
