Product Overview
641B-4-LED is a series 641B air velocity transmitter with LED display which uses a heated mass flow sensor suitable for dirty air flow applications. Typical applications include exhaust stack flow monitoring, air control in drying processes, HVAC air velocity measurements, fan supply and exhaust tracking and clean room ventilation monitoring.
- Stainless steel sensor suitable for dirty air flow measurement
- Ranges from 250FPM (1.25MPS) to 2000FPM (10MPS)
- 4-20mA output
- Digital filter for signal damping
- Screw terminal electrical connection
- Loop resistance of 600 ohm maximum, current consumption of 300mA maximum
- Temperature limit of process: -40 to 176°F (-40 to 80°C), ambient: 32 to 140°F (0 to 60°C)
- 12-35VDC, 10-16VAC, 1.5A rating required on supply due to initial power surge drawn by transmitter
