Temperature sensor for engine coolant measurement has flat head with flat ceramic sensors in flat hermetic package with flat leads

摘要

A temperature sensor has a flat head with series connected flat ceramic thermistors (Th) hermetically sealed (V) by two plastic films and contacted by angled flat metal wires (Z1, 2) passing between them and soldered to upper and lower surface contacts. - Independent claims are included for the use of the sensors in physically and chemically aggressive environments.
