Designed and developed by Navitron Systems Ltd. and fully MED Type Approved in accordance with ISO 19697:2016 by TUV SUD, the NT1750 EPR Electronic Pitch and Roll Inclinometer is a robust and accurate instrument which is fully compliant with IMO recommendations and therefore suitable for installation on all SOLAS vessels.
Traditional mechanical “pendulum” type of heel measuring devices can provide reasonably accurate indications of angle, but this is largely confined to static situations whereas in a seaway, pendulum mass and inertia will almost invariably result in significant errors.
The Navitron NT1750 EPR Electronic Inclinometer provides real time and historical (last 3 & 30 minute) graphic Pitch & Roll information to the watch crew and serial data to VDR and BAMS etc.
The NT1750 EPR enables watch personnel to monitor vessel performance and are alerted to the development of potentially dangerous situations such as Parametric Roll and associated instability involving increasingly adverse Heel Angles and Roll Periods.
In addition to carrying MED Type Approval, the NT1750 EPR features an alternative display screen which is provided for Escort Tug towing operations in accordance with Bureau Veritas (BV) Classification Rules NR467 January 2025 “Rules for the Classification of Steel Ships / Part E – Service Notations for Offshore Service Vessels and Tugs”.
This display is based on Tug Master adjustable Red (Danger – immediate action required) Amber (Action required) and Green (Safe) Heel Angle Zones (as suited to vessel safety in current towing circumstances) and allows watch personnel to monitor Heel Angles which, in the event that safe levels are exceeded, are visually and audibly alarmed for corrective action to be taken.
The control heads provide installation menu selectable Standard and Reverse Display Formats plus Manual or Auto alarm cancellation options. The standard / single head system comprises Control Unit, Distribution Unit and Sensor Unit. The Distribution Unit contains power supply filtering, remote dimming circuitry, VDR interface and BAMS monitoring and alert interfacing. All power and interface cable connections are routed to the Distribution Unit with a single 4 core cable going to each Control Head. The Sensor Unit is a sealed, factory calibrated unit fitted with 3m of cable for connection to the Distribution Unit via a 2 Entry Junction Box also supplied. (Please note that the Junction Box is not needed if the Sensor Unit is within 3m of the Distribution Unit).
The NT1750 EPR Inclinometer system operates on 24Vdc supplies (Main and Back Up) and can be installed in single or multi head display configurations (4 x heads maximum). The system also features a 7” IPS display with 80° viewing angle and remote dimming facility.
