From the manufacturer's datasheet for MWF+ RS485 Modbus.
Overview
The MWF+ measures the average air temperature across the whole length of its sensing element, which makes it suited to large ducts and coils where temperature stratifies. A spring at the connection head reduces vibration and mounting angles are included. It has an RS485 Modbus RTU interface and also an analogue output of 0 to 10 V or 0 to 5 V, set by jumper. LCD versions show the reading with a colour changing traffic light function, with thresholds set through the USEapp or uConfig. A hinged cover, tool-free wiring and removable cable entries speed up installation.
