Vigilant™ - Funnel Smoke Monitoring System

Simple Installation by Your Ship’s Crew
The system is supplied in a modular kit format consisting of a Transmitter head (TX), a Receiver head (RX), and an optional Operator Interface (OI) control unit. No specialist knowledge is required to install and commission the system meaning it can be fitted by your ship’s crew.

Self Cleaning for Optimum Performance
Both the TX and RX heads are supplied with an air-purge body which when connected to a high volume of clean low pressure air (a blower is recommended) will resist particle deposition on the lenses and further lengthen service intervals.

Rugged and Reliable
Vigilant™ has no moving parts, is of rugged design, and has an excellent reliability record. Maintenance simply involves cleaning the TX and RX lenses, which are easily accessible due to the latched head design.

• Low maintenance (no moving parts or perishables, and easy optics access)
