An indirectly heated thermistor comprises a thermistor element 1 constituted by a single crystal semi-conductor, a heater 4 for heating the element, and an insulating film 3 between the heater and the element. In a preferred embodiment the crystal 1 consists of germanium containing less than 10<SP>14</SP> atoms/c.c. of an impurity such as antimony and having goldantimony electrodes 2, the insulating film 3 consists of silicon monoxide, and the heater 4 consists of a deposited layer of nickel-chromium alloy having gold-chromium electrodes 5. The heater is protected by a further silicon monoxide film 6. The thermistor may be mounted by means of glass supports on a header and hermetically sealed in an enclosure. |
