Rökgasgivare typ?

[thomasx]

Hejsan

Vad är det för typ av rökgasgivare till Thermia 15D, pt100, termoelement typ K, eller vad?

Den som följde med blev dessvärre söndersliten vid lite rörarbeten igår kväll. Tänkte att det kanske kunde funka med något jag har hemma.

Hi i think its a NTC-Sensor.

NTC 25K or something like that!

You could measure the resitance at 25° and you know the type.

Hi

Thanks for your answer! I've taken the sensor apart and will put the small sensor element under the microscope to see if I can measure it and perhaps even repair it.

Regarding NTC, they usually don't go much above 100 °C. But if you have any additional info, I'd be happy to know.

REPAIRED!

I hope.

After some nano work under the microscope I managed to solder the wire back onto the glass-casted sensor again, after having removed some of the glass in order to free some area to solder the wire onto.

It did indeed seem to be an NTC, 50k @ 24 °C.
