N3000-SAP Engine Safety System

Name: N3000-SAP Engine Safety System
Brand: NORIS Group

Compact engine safety system monitoring combustion engine operating parameters and triggering emergency shutdown; digital signal processing, wire-break monitoring, IP65 stainless housing, class approved.

Description

The N3000-SAP safety system electrically monitors the basic operating parameters of a combustion engine and is the central unit for triggering an emergency shutdown to prevent damage. Its compact, robust design makes it suitable for installation on ships directly on the engine. Signal processing is purely digital, combined with fast, crystal-accurate speed acquisition.
