From the manufacturer's datasheet for FTB+ active.
Overview
The FTB+ active measures relative humidity and temperature in a stainless steel head that is almost invisible once fitted. It is plastered into flush boxes or installed in hollow walls, which suits museums and exhibitions where sensors must be discreet but accurate. It has two 0 to 10 V or 0 to 5 V outputs, set by jumper, and a 15 m cable to the USE-M housing. The sensor head comes in 34 mm and 66 mm lengths. Dew point, absolute humidity and enthalpy can also be output.
