FT205EV Wind Sensors
– User Manual
1 INTRODUCTION
1.1 Product Overview
The FT205EV is the first in a new generation of lightweight ultrasonic wind sensors. It has a unique
combination of low weight (100g) and a wind speed range up to 75m/s.
The FT205EV (Evaluation Version) features a graphite and nylon composite body. The light weight of
the FT205EV together with the proven FT Acu-Res® technology make it ideal for use on aerial drones
and other weight-critical applications. It has low levels of electrical emissions and is highly resistant to
interference from vehicle systems. During development the sensor has been HALT
(‘highly accelerated
life test’) tested up to 60G demonstrating its operational strength.
The FT205EV allows configurable RS422 (full-duplex), RS485 (half-duplex) or buffered UART (full-
duplex) communication outputs (3V and 5V TTL compatibility). It has been designed for easy integration
and uses a Molex CLIK-Mate connector (Molex part number: 505405-0860). The sensor is provided
with a 600mm cable (Molex part number 15135-0806).
