From what I've seen, using the string in "SENSOR_DEFINITION" works well enough. You can include the human readable units in that string. I my controller, when I see a mfg specific Type or Unit, I just display it as a unit-less number.

The "Signal Strength (dBm)" shown in the attached graphic is a good example. I've also seen it done with "Lamp Blower RPMs". The user gets the information they need.

Pedantic: For dBm, I believe a type of SENS_POWER would be appropriate. dBm is a power ratio relative to 1 miliwatt.
