These air velocity transmitters allow you to take measurements remotely over time. Use them for HVAC/R troubleshooting , clean rooms, and plant maintenance applications.
This transmitter uses a heated mass flow sensor which allows for precise velocity measurements at various flow rates and temperatures. The 641's 16 field selectable ranges provides it the versatility to be selected for several air flow applications. The optional LED produces a complete, low-cost solution for local indication of air flow.
Uses a heated mass flow sensor, which allows for precise velocity measurements at various flow rates and temperatures. With 16 field selectable ranges from 0-250 to 15,000 FPM (0-1.25 to 75 MPS) it provides versatility for multiple of applications. Longer cable lengths are available for ducts that are at very high elevations from the plant floor.
