Dwyer air velocity transmitter Four Field Selectable Ranges from 0-200 to 0-12,000 FPMLinear, 4-20 mA Output Signal, 2% Accuracy at an Affordable Cost * Rugged steel NEMA 13 housing with 12" stainless steel probe on 6' connecting cable. Liquid tight cable entrances. * The Dwyer Series 640 air velocity transmitter is ideal for a wide range of HVAC measurement and control applications, particularly in complete building control and energy management systems. Designed for use in reasonably clean and dry air streams, applications include multipoint air velocity measurements, supply and exhaust fan tracking, industrial hygiene and clean-room systems, air pollution studies and manufacturing or process control system Ranges: 0-200, 0-1000, 0-3000, 0-12,000 FPM (field selectable: referenced to standard conditions). ELECTRICAL Power Supply: 18-24 VAC, 22-28 VDC. Output Signal: 4-20 mA DC. Loop Resistance: 0-300 Ohms. Current Consumption: 250 mA maximum. Warm-up Time: 3 to 5 minutes. * ACCURACY: (% of F.S.) <0-200 fpm range 5% @ 32-180 F; 9% @ 0-32 F or 180-200 F. 0-1000, 0-3000 or 0-12,000 fpm ranges 2% @ 32-180 F; 6% @ 0-32 F or 180-200 F. * Temperature Ranges: Operating: -32 to 160 F; Storage: 0 to 200 F used, very god condition, shelf J3 (Dwyer air velocity transmitter 640-0 was posted and is owned by: Sheila Hopkins) |
