E+E EE576 Specifications
EE576
The compact EE576 probe is optimized for low air velocity
measurement in applications like laminar ow control or lter
monitoring. It operates on the hot-lm anemometer principle
which stands for high accuracy and fast response time.
Reliability
The the ow sensing element manufactured in state-of-the-art
E+E thin-lm technology is highly insensitive to contamination and
oers excellent long-term stability.
Easy installation
The alignment strip on the probe facilitates the correct positioning
in the air ow. The mounting ange within the scope of supply
enables precise setting of the immersion depth.
Output
The measured data up to 1 m/s (200 ft/min) or 2m/s (400 ft/min) is available on the 0-5V or 0-10V output.
Probe for Very Low Air Velocity
Typical Applications
laminar flow control
filter monitoring
outstanding accuracy and long term stability
excellent price/performance ratio
easy and fast mounting
