Dwyer德威爾 風(fēng)速變送器 AVUB-1-V AVUB-2-V AVUB-3-V 風(fēng)速傳感器

The SERIES AVU Air Velocity Transmitter is ideal for a wide range of HVAC

measurement and control applications, particularly in complete building control and

energy management systems.

The Series AVU Transmitter operates by measuring the heat loss from one of the two

sensing elements in the air stream, then calculating the air velocity. Units are virtually

immune to drift due to the design of the sensing element, which makes the transmitter

accurate over the whole air velocity range.

FEATURES/BENEFITS

? 4 to 20 mA or 0 to 10 V output versions

? NEMA 6 (IP67) enclosure rating

? AC or DC powered (loop version DC only)

? 5% or 8% accuracy

APPLICATIONS

? Zone control in HVAC systems

? Supply and exhaust fan tracking

? Clean room systems

? Air pollution studies and manufacturing
