Manufacturer: Dwyer Instruments Brand: Dwyer Model: 641-6

The Dwyer series 641 air velocity transmitter combines a hot-wire anemometer that has 16 user-selectable ranges for measuring air velocity in m/s or fpm with a transmitter that provides an isolated 4 to 20 mA output signal proportional to the measured velocity. Designed as a three- or four-wire device, the transmitter has screw terminals for connecting to either an AC or DC power source and to a power or loop receiver (sold separately). Its 1/2" male NPT process connection allows direct mounting to pipe fittings or a pipe flange, and it may also be mounted using a 5/16" compression fitting. An adjustable output filter stabilizes readings when measuring turbulent flow. The unit is for use with clean, dry air and compatible, non-combustible gases. It has European Conformity (CE) marking. Models are available with various probe lengths, without or with an LED display for observing readings at the point of measurement. The 4-1/2 digit red LED has resolution of 0.01 m/s, 1 fpm (10 fpm at 10,000 and 15,000 fpm ranges). This anemometer is used for monitoring and measuring air flow in HVAC (heating, ventilation, and air conditioning) systems, exhaust stacks and hoods, and clean rooms, among other applications.

Ideal for use with our precision manometers and air velocity gauges, Dwyer® Pitot Tubes are constructed from corrosion resistant stainless steel for a lifetime of service. ASME design meets AMCA and ASHRAE specifications for maximum accuracy over a wide variety of flow conditions. No correction factors required as ASHRAE tip design yields a calibration factor of 1. ASHRAE design needs no calibration! Permanent, stamped insertion depth graduations on sides of 160 series facilitate accurate positioning. Static pressure port is parallel to sensing tube allowing quick, easy alignment of tube with air flow. Low sensitivity to misalignment gives accurate reading even when tube is misaligned up to 15 degrees. Various standard sizes are available for use in ducts as small as 4" dia. or as large as 36 ft. dia. A universal model fits user supplied 3/4" schedule 40 (standard) pipe in any length. Several convenient mounting options are available for permanent installations.
