I'd like to make people aware of two new BB - torque Senors witch look really interesting.
One is the "New Generation Sempu T4" measuring torque on both sides cause measuring the chainring-force.

with following specs: the other one the Bafang SR PA31.32.ST and other Versions of it.
Using the same mesuring method, but with different specs.

Specs.: the interesting thing on Bafang is the the
cause that ??could allow to use the Bafabg without potential Pre-Controller like CA in any throttle-input.Input Voltage(DCV) 4.2 - 5
Output Voltage(DCV) 0.74 - 3.2
But it could also be that it is specially produced for bafang controllers and would make strange behaviour acting as throttle.
So my main Motivtion for this thread is, instead of buying and testing both by my own, and mayb finign out that one of them is trash, i ask you for potential experiences with those Sensors ???
