# NTC Thermistor Identification

I would like to replace original NTC sensor for: https://www.aliexpress.com/item/TGT70-EP-Thermoregulator-Touch-Screen-Heating-Thermostat-for-Warm-Floor-Water-Electric-Heating-System-Thermostat/32669215824.html?spm=2114.13010308.0.64.mHnkr7 with self-made NTC probe. The problem is that manufacturer doesn't want to share any information on it. All I got is the picture and short description of it (not type or chart/table). Can anybody help to identify it?

Thanks

• Do you have a close-up photo of the sensor with the cap removed? – Dmitry Grigoryev Sep 7 '16 at 12:34
• You'll have to match the sensors Temperature-resistance curve, If I was the manufacturer I wouldn't let you do that either because if you don't do it correctly you might break their system. – Voltage Spike Sep 7 '16 at 16:24
• Assuming the yellow text is correct, you have all you need. It is 10k at 25C, and the beta value is 3950. You can read about NTC beta on wikipedia or some other website. en.wikipedia.org/wiki/Thermistor – mkeith Sep 7 '16 at 16:51

A reasonable and moderately educated guess would be that it's $\beta_{25/50} = 3950K$ but definitely confirm it.
