K85 reuses the core sensor optics from the S8 module, but comes pre-assembled on a robust PCB-board with industrial standard analogue outputs, e.g. 0 to 10V and 4 to 20mA and wide input voltage tolerance with reverse polarity protection.

Pin layout for additional connectors and terminals allow for further options; e.g. thermistor for temperature and potentiometer for temperature offsets. The article is prepared to be mounted in an suitable enclosure as a wall-mounted or duct-mounted transmitter.
