Abstract

There are some specific applications ,.1 xerographic copiers for a non-contacting temperature sensor. The most obvious is for fuser roll temperature control. A non-contact temperature sensor is described using a thinistor infra-red detector. The non-contact temperature sensor consists of the following: (1) VECO Thinistor Infra-Red Detector mounted in a 6-pin TO5 type header; (2) electronic circuit for amplification and ambient temperature compensation; and (3) plastic housing with heat shield to enclose the detector and electronics and to provide a more stable environment.
