Abstract: A temperature control unit includes a fitting, a heating wire, a first temperature sensor, and a housing, which contains the first temperature sensor and portions of the fitting and the heating wire. The fitting includes a fluid inlet, a fluid outlet, a flow channel extending from the fluid inlet to the fluid outlet, and a passage extending through a wall of the fitting to the flow channel. The heating wire extends through the passage and into the flow channel. The first temperature sensor is secured to an external surface of the fitting opposite the flow channel and is electrically connected to the heating wire.

Abstract: A pump system for pumping a fluid includes a motor housing, a motor, a rod, a positive displacement pump, a position sensor, and a controller. The motor is located within the motor housing. The rod is connected to and driven by the motor and the positive displacement pump for moving a fluid is driven by the rod. The position sensor produces a rod position signal that is a function of a position of the rod, and the controller produces a drive signal for driving the motor as a function of the rod position signal.
