Luke343,
You could try using that transducer with a MB-1100, however the MB-1100 was designed to be pared with a Furuno transducer(s). The impedance of the Radarsonics transducer is different so I can't speak to how well it would work. As far as the temperature goes, it appears that the Radarsonic transducer is using a 10k temperature sensor so it should work if connected to the DFF1.
