I´m looking for the Watchport/D sensor dimmensions but I can´t find it in any document. I would like to know also if it can works fine behing a glass and which are the limitations. Can anybody help me?
See page 3 of the Watchport Sensors datasheet for dimensions:

Yes, the sensor works behind glass.
