CBR101 sensors
renatoa
Hi,

Tried a lot to find this info before starting a new thread, but no outcome...
Anyone knows what type are the Gene sensors ?
Measured them and don't show low resistance as a thermocouple but something in the 236 Ohms ballpark, at 25 C ambient.
Could this be a Pt sensor ?

Thank you for any hint !

Nothing useful, been there...

"Replacement outlet/inlet temperature sensor for the Gene Cafe CBR-101."

This thread suggests RTD https://coffeesno...fully.html
Also See this thread ("the one in the GC is a negative coefficient thermistor with a room temp resistance of about 1Megohm") https://coffeesno...ogger.html

Yep, RTD, with negative temperature coefficient.
The previous measurement was faulty, they are in the 250K ballpark at ambient temperature and go down to 30-50k when a 300 C hot gun is aiming the heater assembly.
