FT702LT Flat Front Wind Sensor Manual
Figure 2 shows
how to identify an FT702LT’s build version and individual serial number, depending on
which main label is attached.

Figure 2: Examples of Main Sensor Labels
Only sensors marked with the Intertek label conform to UL 61010-1 and are certified to CAN/CSAC22.2
No. 61010-1-04. Some early build versions do not have this certification.
1.3 Pipe Mount Sensor
It is possible to mount the wind sensor directly on top of a pipe. Details of the Pipe Mount sensor and
system can be found in a separate manual. The Pipe Mount sensor offers enhanced environmental
sealing, lightning protection, thermal conductivity and corrosion resistance. The base of the Pipe Mount
sensor is different to the Flat Front sensors described in this manual. Please contact FT Technologies
for further information.
1.4 Scope of Use
The FT702LT is designed, manufactured and optimised for high availability. The FT702LT wind sensor
often attains 99.9% or better availability of wind speed and wind direction readings.
No promise in part or full can be given to guarantee an FT702LT wind
sensor’s continuous operation,
as exceptional circumstances can occur that may result in the failure of the output from a sensor.
Exceptional circumstances can include:
Poor installation
Inadequate inspection
Power supply failures
Poor quality electrical connections
Lightning exposure
Problematic environmental conditions or combination of conditions
Typically higher levels of wind speed and wind direction data availability are achieved through the use
of an additional FT sensor or an additional mechanical or ultrasonic sensor. Control strategies or
algorithms, which compensate in whole or in part, for any temporary interruption of data from individual
sensors should also be applied. The choice and implementation of such methods is entirely the
Purchaser’s responsibility.
