Hi guys,
Does anyone know what is the thermal sensor on ordinary А4 paper laminators? It si look like a diode?
Does anyone have a circuit of any A4 paper laminator?

Hello,

On my laminator, it is a diode like 1N4148.

They use then as thermosensor.

Diode have linear temperature coefficient of about 2.3 mV/C when a forward voltage is supplied across the junction.

According to datasheet it should work up to 200 degrees celcius and above...

There is an example on : http://www.micro-examples.com/public/microex-navig/doc/098-temperature-sensor.html

Best Regards.
