INTRODUCTION

1.1 Product Overview

The FT702LT/D is a solid-state ultrasonic wind sensor which uses a patented Acoustic Resonance airflow
sensing technique to measure accurately both wind speed and direction. The FT702LT/D has been specifically
designed to operate in harsh environments such as offshore and lightning and ice-prone areas. The wind sensor
has no moving parts to degrade or wear-out and is designed for applications requiring high reliability. T he
FT702LT/D helps reduce costly down-time and unscheduled maintenance visits.
Mounting and aligning the sensor is very straightforward. The mounting flat on the sensor body defines the 0
wind datum so that the sensor automatically aligns to a reference point. For operation in ice-prone areas the
FT702LT/D is fitted with a highly effective thermostatically controlled 'all-body' heating system. A three element
heater (one element located in the top of the sensor and two in the bottom) is used to ensure that heat is evenly
distributed over the entire surface area.
