Dwyer® 641-6-LED Air Velocity Transmitter, 6" Probe, LED Display, 1/2" NPT, 4 to 20 mA, 100 psi, Series 641

Dwyer 641-6-LED Air Velocity Transmitter is a meticulously engineered tool for precise air velocity measurement. It harnesses the power of cutting-edge heated mass flow sensor technology to deliver dependable results across various flow rates and temperatures.

Boasting a 16-field selectable range, the 641 transmitter seamlessly conforms to a broad spectrum of air flow measurement needs. Equipped with an LED display, it offers immediate and easily visible local readings of airflows, ensuring swift, hassle-free monitoring on-site. Its display shines brightly and attractively, enabling clear visibility even from afar and under tough conditions. A push-button setup makes it even more of a user-friendly tool. 

Designed for use with clean air and compatible non-combustible gases, the 641 transmitter also offershigh accuracy across its selectable ranges. With ranges extending from 250 FPM (1.25 MPS) to 15,000 FPM (75 MPS) , it caters to a broad spectrum of needs. It achieves optimal performance in a myriad of areas in addition to supplying fresh air to clean rooms and verifying proper lab hood exhaust flow rates. It also monitors exhaust stack flow, controls air in drying processes, and conducts HVAC air velocity measurements. Response time in flow is 1.5 seconds to 95% of final value (output filter set to minimum).

Compact housing offers installation flexibility and space efficiency. With a smaller footprint, it can easily be integrated where space is premium. The digital filter provides a high level of control and versatility for signal damping, preventing data loss and keeping systems responding smoothly without excessive lag. 

Includes 6" probe.
