NINGLU 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 officersto 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.
Electronic Inclinometer IM330 consists of the main unit and inclination sensor.
The inclination sensor sends roll and pitch messages, in the form of RS485 digital interface, to the main unit.
There is digital and analog display of the roll and pitch angles on the main unit.
In the meanwhile, the messages of date, time, longitude and latitude are from GPS.
And IM330 sends the roll angle and pitch angle to VDR,ECS and so on.

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.
