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.

Industrial control projective capacitive touch interface

An industrial control device includes a display, a body, and a controller. The body includes a capacitive slider sensor, a graphic, and a window. The graphic overlaps the capacitive slider sensor. The window is transparent and aligned with the display to permit the display to be viewed through the window. The controller is coupled to an output of the capacitive slider sensor to receive signals from the capacitive slider sensor. The controller is coupled to the display and configured to control the display.

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.
