I’ve replaced both DBC12507 sensors last night. I took the old ones home and did some measuring.
Room temp of around 24C, resistance 700ohm
Apply hairdryer to sensor and it sweeps from 700 to 850 within about 2 minutes. Both. Then from 850 to 900 takes another 2-3 minutes.
Even after heating there is some output of around 4mV when I wave a drill bit infront of the sensor as close as I could get to it without the magnetic force grabbing. If I let it grab the drill bit it hits around 40mV.
I know the output should be in the region of 400mV from the specs of SEN8 (D-K) but I don’t have an oscilloscope so sorry that’ll have to do (and I suspect the specs for our SEN8 S are the same).
Forgot to do the same test with new sensors and don’t feel like crawling back down again.
Can someone who is about to replace their dbc12507 and who has access to a multimeter AND a hairdryer do the same test on a new sensor.
