Ordered a torque sensor from this seller a few weeks ago:-

...it's a T2 10-24v version. It's being powered from the 15v line tapped from a Kunteng S06S type controller, this measures 15.3 volts and is stable. Finally got around to testing it today and had issues from the outset. Checked the torque sensor o/p voltage (white wire, disconnected from controller for testing), at rest this was 3.02v, dropping to around 2.0v if I really stood on the pedals, but with normal pedalling didn't deviate much from the 3.02 rest voltage.
This looks completely wrong to me, I was expecting about 1.5v at rest rising to 4.0v or so at full pedal pressure. I'm completely unfamiliar with torque sensors though, so before I condemn it I wondered if anybody could confirm that my thinking is correct here...?
