Title: Laminator thermo sensor Post by: raidera on February 07, 2010, 11:01:07 11:01 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? Title: Re: Laminator thermo sensor Post by: borberk on February 08, 2010, 08:10:10 08:10 It is 100°C bimetal NC switch.

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 (http://www.micro-examples.com/public/microex-navig/doc/098-temperature-sensor.html) Best Regards.

Thank you very much titi Title: Re: Laminator thermo sensor Post by: David_1 on June 30, 2012, 09:51:53 09:51 old post yes I know :-)
we are buying battery packs from china the 10k themister looks just like a 1n4148 too :-) |
