Model 641B Air Velocity Transmitter

This air velocity transmitter offers precise airflow measurement for HVAC systems, clean rooms, tunnels, drying chambers, or any environment where knowing air speed is essential. It uses precision sensors and a streamlined aerodynamic design to reduce turbulence, improving the accuracy of flow readings. The output is compatible with standard signal converters, making integration easy with building automation, PLCs, or environmental monitoring systems. Built with rugged housing, it withstands changing environmental conditions and is calibration-ready, with support available locally for setup and verification.
