Cảm biến tốc độ không khí E+E EE660-T3A7L300K2 | Air velocity transmitter fission
(24VDC 0-10V/ 4-20mA 0-2mps +/-2% +0.06mps)
Low Air Velocity Sensor
EE660
190 v1.4 / Modification rights reserved The EE660 is optimized for highly accurate measurement of very low air
velocity in laminar flow control and special ventilation applications, for instance in clean rooms.
Excellent Measurement Performance
The E+E thin film sensing element employed in EE660 operates on the hot film anemometer principle, which stands for excellent accuracy down to 0.15 m/s (30 ft/min), high insensitivity to pollution and low angular dependency.
Analogue and Digital Outputs
The air velocity measured data is available as current and voltage outputs, on the RS485 interface with Modbus RTU or BACnet protocol, as well as on the optional display.
Easy Configuration and Adjustment
The EE660 is user configurable with jumpers on the electronics board or via software. An optional configuration adapter and the free EE-PCS Product Configuration Software facilitate the adjustment of EE660 and the display setup.

1) Selectable by jumper, only for analogue output
2) The accuracy statement includes the uncertainty of the factory calibration with an enhancement factor k=2 (2-times standard deviation).
The accuracy was calculated in accordance with EA-4/02 and with regard to GUM (Guide to the Expression of Uncertainty in Measurement).
3) Selectable by jumper (analogue) and slide switch (digital)
