Part numbers
From the manufacturer's datasheet for AKF10+ RS485 Modbus.
Overview
The AKF10+ measures air temperature in ventilation and air conditioning ducts and in other gaseous media. With a thermowell it also works as an immersion sensor. The probe is 6 mm stainless steel and comes in seven lengths from 50 to 450 mm. It has a Modbus RTU interface on RS485 as well as 0 to 10 V or 0 to 5 V outputs. It is set up with the USEapp, uConfig, jumpers and DIP switches. The LCD version has a colour display with a traffic light function. A hinged cover and tool-free wiring speed up installation, and a mounting flange is included.
