SIERRA Tachometer, Matrix, Smartcraft
This 3-inch tachometer is engineered for marine propulsion systems equipped with Smartcraft digital engine monitoring. The gauge integrates directly into Smartcraft networks via CANbus connectivity, eliminating the need for dedicated wiring to the engine and providing real-time RPM readout alongside other networked engine parameters.
The instrument housing is constructed to IP 67 specification, ensuring full protection against saltwater spray and washdown. Its compact bezel outer diameter of 3.86 inches fits standard flush-mount gauge openings, while the 4.3-inch panel depth accommodates most console configurations. The gauge operates reliably across the full range of marine conditions, with an operating temperature range of -40°C to +85°C.
Power consumption is minimal at 0.15 to 0.20 amperes on 12 VDC systems, making it suitable for both single-engine and multi-engine installations without placing significant load on the electrical system.
