DWYER INSTRUMENTS Air Velocity Transmitters

Dwyer Instruments air velocity transmitters are designed for providing precise measurement of the lowest air velocities in HVAC systems and cleanroom ventilation monitoring applications. These units feature heated mass flow sensors to deliver accurate velocity measurements, within 1.5 seconds, at varied flow rates (250 - 1500 fpm) and temperatures (-40 to 212 degrees F). They come equipped with an easy push-up button design for carrying out frequent field calibrations and a compact housing for complete protection against environmental hazards. Selected models are further integrated with a 6-inch-long cable to connect the sensor with electronic enclosure and mount the unit in an easily accessible position. Choose from a wide range of these products available in 5/16 and 1/2 inch diameter options on Raptor Supplies, an authorised Dwyer Instruments distributor.

Features

• These CE-marked transmitters feature a heated mass flow sensor to provide precise velocity measurements at flow rates ranging between 0 and 15000 FPM and a push-button set-up facility for hassle-free calibration.
• They are capable of being operated at temperatures ranging from -40 to 212 degrees F.
• Selected models come equipped with a digital filter to dampen the signals and a NEMA 4X-rated enclosure for installation in confined spaces.
• Dwyer Instruments 641 Series air velocity transmitters feature digital filter for eliminating noise, fluctuations and unwanted artefacts from the raw sensor signal, resulting in a cleaner and more reliable output. Selected models feature a bright led display for getting readings in low-light conditions. NON-LED variants have NEMA4X enclosures for preventing contaminants. These air velocity transmitters can be operated at pressures up to 100 psi.
• Dwyer 641RM Series air velocity transmitters with remote probes feature a compact design for installation in tight spaces. They are equipped with function buttons for easy setting up of them. These air velocity transmitters have screw terminals for easy connection and strong conductivity. They have a measuring range of 250 FPM to 15000 FPM. These air velocity transmitters have ambient operating temperatures ranging from 32 to 140 degrees F.
