This document is the installation manual of AF1 series measurement transducers. It introduces the installation methods and usage methods.
The document serves as a short instruction manual for the ROTRONIC AF1 series measurement transducers, designed for airspeed measurements. It covers general descriptions, dimensions, connection types (duct and cable versions), and mounting procedures to ensure precise airflow detection in various environments.
Key operational features include manual zero adjustment via an AUTOZERO button and reconfigurable settings using DIP switches. The guide details electrical installation precautions, terminal allocation, power supply requirements, and communication protocols such as Modbus RTU over RS-485.
