THERMOGRAPH WITH BUILT-IN CONTROLLER THEREIN

摘要

PURPOSE: A thermograph with a built-in controller is provided to prevent an abnormal operation of a machine and record a temperature change when the machine is operated. CONSTITUTION: A sensor measures a temperature through an input port. The sensor converts the measured temperature into a current. The sensor output the current to a printer and the measured temperature to a display window. When the measured temperature is lower than a reference temperature, a power is supplied to a controller to turn on a peripheral device. When the measured temperature is higher than the reference temperature, the power supplied to the controller is intercepted.
