Temperature control. (Instruments).The application of fluidized epoxy powder or other thermosetting thermosetting, adj having the property of becoming irreversibly rigid or hardened with the application of heat. In dentistry the term is used in connection with resins. material to metal piece parts by an on-line flow coating or spray coating process is said to require that piece parts have a consistent, close-tolerance temperature when they reach the coating station. If the temperature is too high, over-coating will result with attendant inferior dimensional characteristics. If the temperature is too low, under-coating will result with failure to achieve proper coating thickness which yields inferior electrical insulation Electrical insulation A nonconducting material that provides electric isolation of two parts at different voltages. To accomplish this, an insulator must meet two primary requirements: it must have an electrical resistivity and a dielectric strength characteristics. The temperature tolerance is easily determined and can be accurately specified. The problem is said to be how to assure that each piece part is within the temperature tolerance when it is in the work station, ready for coating. A system has been developed to measure each and every piece part the moment it reaches the coating station, and without the necessity of touching the piece part. The temperature is measured precisely by means of infrared techniques. The infrared energy that is radiated in the invisible portion of the electromagnetic spectrum electromagnetic spectrum Total range of frequencies or wavelengths of electromagnetic radiation. The spectrum ranges from waves of long wavelength (low frequency) to those of short wavelength (high frequency); it comprises, in order of increasing frequency (or decreasing is sensed by a non-contacting IR sensor See IR detector. that is trained on the part in the work station. The sensor provides instantaneous temperature readings, with repeatability as accurate as [+ or -] 2[degrees]F, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. the company.
