摘要： A heating system includes at least one electric heater disposed within the fluid flow system. A control device includes a microprocessor and is configured to determine a temperature of the at least one electric heater based on a model and at least one input from the fluid flow system. The control device is configured to provide power to the at least one electric heater based on the temperature of the at least one electric heater.

摘要： A method of predicting the temperature of a resistive heating element in a heating system is provided. The method includes obtaining resistance characteristics of resistive heating elements and compensating for variations in the resistance characteristics over a temperature regime. The resistance characteristics of the resistive heating element include, but are not limited to, inaccuracies in resistance measurements due to strain-induced resistance variations, variations in resistance due to the rate of cooling, shifts in power output due to exposure to temperature, resistance to temperature relationships, non-monotonic resistance to temperature relationships, system measurement errors, and combinations of resistance characteristics. The method includes interpreting and calibrating resistance characteristics based on a priori measurements and in situ measurements.

摘要： A control system for a heating system of an exhaust system is provided. The control system includes at least one electric heater disposed within an exhaust fluid flow pathway, and a control device adapted to receive at least one input selected from the group consisting of mass flow rate of an exhaust fluid flow, mass velocity of an exhaust fluid flow, flow temperature upstream of the at least one electric heater, flow temperature downstream of the at least one electric heater, power input to the at least one electric heater, parameters derived from physical characteristics of the heating system, and combinations thereof. The control device is operable to modulate power to the at least one electric heater based on at least one input.

摘要： An industrial control device includes a display, a body, a first sensor, and a controller. The body includes a facia wall, an inner shroud, and an outer shroud. The facia wall includes a window that is a transparent material aligned to permit the display to be viewed through the window. The inner shroud extends rearward from a rear side of the facia wall. The outer shroud is disposed about the inner shroud and extends rearward from the rear side of the facia wall and is spaced apart from the inner shroud to define a cavity. A seal member is within the cavity forms a seal with a facia plate disposed about the inner shroud. The first sensor detects contact with a front surface of the facia wall. The controller is coupled to an output of the first sensor. The controller is coupled to the display and controls the display.
