Introduction

Introduction

The marine weather station AM706D is a multi-functonal

measuring instrument with wind speed, direction, temperature,

humidity and barometric pressure. It can accurately measure and

display real-time relative wind speed and direction, true wind speed

and direction, air temperature, relative humidity and barometric

pressure. In addition, it can regularly print these parameters and

time, longitude and latitude, ship speed, and navigational signal. It is

important and necessary for observation and safe navigation.

AM706D is approved by China Classification Society (CCS).

The main unit AM706D adopts three mounting methods, table,

hung and flush mounting. The wind sensor AM706S should be

installed on natural ventilated place, such as mast. Please note, big

Radar antenna rotation can disturb the wind measurement. The

AM706TH is suggested to be mounted on a place there is no direct

sunlight and rain drop.

Measurement Principle

2

Wind sensor sends relative wind direction and speed signal (relative

to ship bow and absolute value of angle signal) in digital interface

format of RS422 to main unit through junction box.

Temperature and humidity sensor provides air temperature and

humidity signal in digital interface format of RS485 to main unit

through junction box

Barometric pressure signal is received from internal IC sensor of

main unit.

Main unit uses these signals to calculate, display and export.

True speed and direction:

There are two ways to get the true direction and speed.

First way, connecting external GPS (RMC) data input, main unit can

calculate true wind direction (relative to North Pole) and speed.

Second way, connecting both Gyro(HDT) and Speed Log(VBW) data,

main unit can display the true wind direction and speed.

Maintenance

Main Unit

The main unit is maintenance-free.

If doing the cleaning, use soft cloth and mild detergent, and avoid

water drop.

Sensor Part

When there is ice or dirt on sensor to disturb the normal work, please

clear in time.

Regularly check external mounting bolts to avoid looseness and the

abrasion and ageing of cables

When the equipment breaks down, please contact our engineers of

after-sale service department in time. Please do not do the service

by yourself.
