Faria Chesapeake White SS 4 Tachometer w/Hourmeter (4000 RPM) (Diesel) (Mech. Takeoff & Var. Ratio Alt)

Faria Chesapeake White SS 4 | Diesel Maintenance & Ratio Authority

Faria Chesapeake White SS 4-inch Diesel Tachometer addresses the specific monitoring needs of diesel engines by providing a 4000 RPM scale compatible with both mechanical take-off and variable-ratio alternator signals. By integrating a digital LCD hourmeter, the system mitigates the risk of missed service intervals, providing a precise record of engine run-time. This engineering focus ensures that diesel operators maintain absolute situational awareness of engine speed and maintenance status, preventing premature component wear in demanding offshore and commercial environments.

From an installation standpoint, the Chesapeake White SS features a selectable ratio adjustment to synchronize the gauge with the engine’s alternator or mechanical drive output. In demanding marine conditions, it’s vital to calibrate the unit using a handheld tachometer to ensure the displayed RPM matches the actual crankshaft speed. System performance relies on signal integrity; don’t leave the rear signal terminals exposed to salt air without dielectric grease, as terminal oxidation can introduce resistance that leads to needle erraticism and inaccurate cumulative hour tracking during long-range coastal transit.
