Introduction
Electronic inclinometer IM330 is a device to measure ship hull posture,
including roll actual angle, roll period, roll amplitude, pitch actual
angle, pitch period, pitch amplitude, date, time, longitude and latitude,
and to send them to VDR. It also has alarm function for ship’s officers
to avoid dangerous situations and the alarm messages (date, time,
longitude, latitude, roll angel and pitch angel) are recorded in the
history for check.
Electronic inclinometer IM330 is based on the combination of
mechanical and electronic principle to provide the hull posture during
the ship sailing. The main unit (display) can be separately used with
the inclination sensor. The main unit can be mounted in the methods
of table, hang and flush, and the inclination sensor should be mounted
in horizontal direction and perpendicular to ship mast.
Definitions
Roll
motion around the longitudinal axis of the ship
Pitch
motion around the horizontal axis of the ship
Actual angle
momentary angle of roll or pitch referenced to a leveled
ship to port or starboard side, or to front or back side
Period
Time between two successive maximum values of actual
angle on the same side of the ship
Amplitude
maximum values of actual angle to port or starboard side,
or to front or back side
