Abstract
PURPOSE:To enable a simple constitution to exercise temperature measurement by thermal balance calculation by calculating the digital time required for the temperature transistion of the thermal sense part of a temperature detector between preset temperatures by a computer after heating or cooling the thermal sense part. CONSTITUTION:Putting heater 2, forming the thermal sense part of sensor 10 provided to a measurement object, to work makes contact 1 ON at a fixed temperature and after heating ends, remaining heat causes the temperature to rise, making contact 3 ON. As a result, a current flowing from power supply 5 to the earth 9 via contacts 1 and 3 develops a voltage across terminal 6 and 7, by which timer 2 is turned ON. Once a drop in temperature breaks contact 3, the applied voltage changes to turn timer 20 OFF. Answering to the output of timer 20 equivalent to the time for the transistion of sensor 10 between set temperatures, computer 21 operates to exercise the measurement of the temperature of the object through the simple constitution without an A/D converter. In addition, the same result can be obtained by cooling the sensor down to the fixed temperature and then by making use of the transistion time between two set temperature in a rise.
