  • Thermistor-type temperature sensor
    Patent number: 5481240
    Abstract: A low-cost and compact thermistor-type temperature sensor which has a thermo unit and a metal tube solidly fixed by cement. The sensor has an enlarged reserve space between the thermo unit and the metal tube to accommodate an excess amount of the cement therein, so that intrusion of the cement into electrical connection portions of lead wires is prevented. This enlarged space assures good electrical insulation between the electrical connection portions and stable measurement characteristics.
