Abstract

1,181,872. Thermistors; holding devices. INSTITUT PROBLEM MATERIALOVEDENIA AN USSR. 15 May, 1967, No. 22405/67. Headings H1K and H1P The sensitive semi-conductor element 1 of a thermistor intended for measurement of surface temperature is made of a magnetized ferrite, e.g. barium ferrite, so that the thermistor may be held in contact with the surface by magnetic attraction either to the surface itself, if it is ferromagnetic, or to a complementary magnetized piece placed on the opposite side of a non- magnetic wall whose temperature is to be measured. In the embodiment two barium ferrite elements 2, 3 are separated by a "cold" silver electrode 4 welded to a terminal 12, and are surrounded by a "hot" silver electrode 5 welded to a terminal 11. A diamagnetic heatconducting sleeve 7, e.g. of copper, and a magnetically non-retentive metal casing 6 covered with thermal insulation 10 surround the element, and an iron layer 8 coated with a metal layer 9 contacts the surface to be measured, and the electrode 5. The element may alternatively be separated from the casing 6 by an air space. The contact face of the device is shaped to conform to the surface under investigation.
