LD-RPM96 Marine Analog RPM Indicator
MARINE RPM INDICATOR
The LD-RPM96 is designed to provide clear analog indication of shaft or engine rotational speed in marine propulsion and auxiliary control systems. Its standard 96 × 96 mm panel format allows integration into bridge consoles, engine-room panels, and other marine monitoring equipment.
The wide-angle pointer display can be configured to indicate forward and reverse rotation, including AHEAD and ASTERN markings where required. Standard signal input is ±10V DC, while alternative voltage or current inputs can be reviewed according to the connected controller or speed transmitter. Dial markings, RPM range, illumination voltage, logo, and selected protective configurations are also available for customization.
