Thick Film Temperature Sensors Using Standard Pastes

[摘要] Standard thick film resistor pastes exhibit changes in their electrical characteristics when printed on top of dielectric layers. Of particular interest is the inherent change in their temperature coefficient of resistance.Simple temperature sensors were formed by deliberately printing thick film resistor pastes on top of larger areadielectric layers. Temperature tests carried out on these devices have shown that by selecting the correct pastecombination and resistor aspect ratio stable, repeatable, temperature sensors with good linearity can bemanufactured. A comparison is made of these sensors to other commercially available products currently usedin the thick film industry.
