FT702LT/D Flat Front Wind Sensor Manual
3.4 Inspection of the FT702LT/D
The following checks are required to identify any signs of corrosion or damage on the sensor which may hinder
its performance. It is recommended that these checks be carried out annually.
Mechanical damage
; Check the sensor body for signs of damage, paying particular attention to the seals. Also
inspect for signs of lightning damage which may appear as burns or scorch marks (or burnt smells). If damage
has occurred replace the sensor immediately.
Corrosion
; Inspect th
e sensor’s mounting flat and the mounting bar it is fixed to for signs of corrosion. If
corrosion is present on either surface, it should be removed using an abrasive cloth. Before reinstalling the
sensor, electrical joint compound should be applied to the
sensor’s mounting flat (see section 3.2). Check that
the mounting screw, nut and washer are in good condition with no signs of corrosion and tighten as necessary.
If corrosion is present replace with parts of the appropriate finish (see section 3.2).
Interconnection cable;
Inspect the condition of the cable. If any part has become frayed or damaged in any
way, it should be replaced immediately. Intermittent cable faults may not be visible, but may show up as errors
in data. See section 2.2.4 for details on how to identify such faults.
Connector protective sleeve;
Check for any signs of damage or degradation. If the sleeve is damaged it
should be replaced (see section 3.2).
Cleaning;
the measurement cavity has a special coating which helps to prevent water building up. When water
enters the measurement cavity the surface helps to wash away dust and debris which may have settled. If any
debris is present this can be removed by gently rinsing the measurement cavity surface with distilled water
using a laboratory wash bottle or similar. Please note excess water droplets can be removed by lightly blowing
or shaking the sensor.
