Article Synopsis
This note, a communication from the Development Laboratory of Johnson, Matthey & Co., Limited, describes a temperature controller for resistance furnaces with platinum alloy windings. The control signal is obtained by monitoring the resistance of the winding, so that no separate temperature-sensing element is required. Provision is made for control of the initial heating rate to avoid thermal shock.
