Abstract

A self-calibrating temperature controller adapted for use in controlling closely the temperature of hot-melt adhesive dispensed from an adhesive supply unit is provided. The temperature controller includes a microcomputer operated under a stored program to perform automatically a self-calibrating operation. A non-volatile memory is provided for storing RTD values in a lookup table so as to compensate for the non-linearity of the RTD sensors.
