WERKWIJZE VOOR HET INSTELLEN VAN DE SOORTELIJKE WEER- STAND VAN EEN THERMISTOR, EN THERMISTOR VERKREGEN ONDER TOEPASSING VAN DEZE WERKWIJZE.

摘要

A wafer thermistor with opposite, generally flat surfaces has two spaced apart contacts on one surface and a third contact on the opposite surface; the third contact is considerably larger in surface area than the two contacts on the one surface; the conductors leading to the thermistor are connected to the two contacts on the one surface; to change the resistance of the thermistor, removal of a larger percentage of the surface area of one of the contacts will change the resistance of the thermistor by only a fraction of the surface area of the contact that was removed.
