EE671 (0-20m/s) HVAC Miniature Air Flow Transmitter
HVAC用微型风速变送器
EE671（EE575升级版本）系列是专为HVAC应用而设计的一款紧凑型风速变送器。
产品内置VTQ型风速敏感元件,该敏感元件结合了E+E研发的高品质薄膜生产技术和先进的塑封工艺的优点。
它使用了新型的热膜风速工作原理，保证了测量的高精度和重复性， 并且使产品获得了良好的长期稳定性和优秀的抗污染能力。
EE671风速变送器提供电缆型和接头型两种安装方式。其风速测量范围最高可达20m/s，模拟输出方为0 - 1V, 0 - 5V 或0 - 10V的标准电压信号。
产品的包装盒内配有标准的安装法兰。安装法兰用于现场风速变送器的快速安装， 同时，应确保探杆上的风速流向标记和风道中的实际风流方向相一致。
用户可选用E+E专业的组态软件，通过E+E专用数字通讯接口对变送器进行参数选择和量程设置，并对探头进行校准。
典型应用
- HVAC暖通空调系统
- 流量监测和控制
- 烘箱入口空气监测

HVAC Miniature Air Flow Transmitter
EE671 is a compact air velocity probe for HVAC applications. The built-in flow sensing element VTQ combines the advantages of state-of-the-art E+E thin-film manufacturing and of the newest transfer molding technology.
It operates on the hot-film anemometer principle and ensures high accuracy and reproducibility as well as long-term stability and outstanding resistance to pollutants.
EE671 is available with fix installed cable or with plug connection. The measured air velocity up to 20 m/s (4000 ft/min) is available as linear voltage output 0 - 1 V, 0 - 5 V or 0 - 10 V.
The alignment strip on the probe and the matching mounting flange within the scope of supply simplify installation and correct positioning in the air flow. The flange enables the immersion depth to be infinitely variable.
With an optional configuration kit the user can set via a digital setup interface the output configuration and perform an adjustment of the probe.
Features
- High accuracy and long-term stability
- Outstanding resistance to contamination
- Easy and quick mounting
- User configurable
Typical Applications
- Heating and ventilation systems
