Vetus announced its cooperation with the National Marine Electronics Association to extend an existing NMEA 2000 PGN, or parameter group number, to include waterlock temperature. The enhancement enables real-time monitoring, trend visualization and alerts directly on a multifunction display, contributing to smarter and safer on-board systems and helping users detect changes earlier.
“Collaborating with NMEA ensures that new data fields are implemented in a consistent and compatible way,” Arthur Roeling, director of research and development and aftersales at Vetus, said in a statement. “By adding waterlock temperature to an existing PGN, we bring valuable exhaust-system information directly to the MFD.”
A PGN is a unique numerical identifier used to categorize and define specific sets of data within the NMEA 2000 protocol — a code that groups together related data and allows devices on a network to recognize and interpret information efficiently.
The updated PGN supports measurement of the exhaust gas and cooling water mixture temperature at the waterlock inlet. The temperature can be monitored using an optional sensor package available for select Vetus waterlocks, including the HPWS model within the HPW series.
Initial integration targets new builds using an existing NMEA 2000 backbone, with refit support planned for a later phase.
