How does the temperature sensor in 936 soldering stations work?
(1/1)
technix:
I am seeing conflicting answers: someone claim it being a thermistor and some claim it being a thermocouple. What is it? And how do I find specs about it?

This is for my soldering station project. I intend to use a MCU to implement digital control, but I need to know how the temperature sensor work so I can design the feedback circuitry: should it be a constant current source driving the thermistor and ADC sample it, or should it be one of those thermocouple ADC chips.
hlavac:
In real Hakko 936 it seems to be some sort of thermistor (it says it should have 43 - 58 Ohm resistance according to the manual).
Not sure what the clones of 936 use...
