Faria Chesapeake White SS 4" Tachometer - 4000 RPM (Diesel) (Magnetic Pick-Up)

The Faria Chesapeake White SS 4" Tachometer - 4000 RPM (Diesel) with Magnetic Pick-Up is a marine-grade engine monitoring instrument engineered for diesel-powered vessels and equipment where precise RPM measurement is mission-critical. Built by Faria Beede Instruments, a trusted manufacturer in marine instrumentation, this tachometer serves operators who demand reliable engine diagnostics in harsh saltwater and demanding environments. Whether managing patrol boats, transport vessels, or industrial diesel systems, accurate RPM feedback prevents engine damage and ensures operational efficiency.

This tachometer employs a magnetic pick-up sensing system that detects crankshaft rotation directly from the engine, delivering real-time RPM data without external power dependencies for signal acquisition. The 4000 RPM maximum scale is calibrated specifically for diesel engines, which typically operate at lower RPM ranges than gasoline counterparts but demand higher torque delivery. The perimeter-lighted white dial with contrasting blue and white graphics ensures visibility in low-light conditions, while the polished stainless steel bezel and domed glass lens provide corrosion resistance and durability in saltwater spray environments. The contoured white pointer and electronic circuitry work together to provide smooth, accurate needle response across the full measurement range.

Operators of diesel-powered marine vessels, commercial fishing boats, and utility craft rely on the Faria Chesapeake tachometer to monitor engine health and optimize fuel consumption during extended operations. Installation requires connection to the magnetic pick-up sensor near the engine block or flywheel—standard practice on diesel systems—and basic electrical integration to the vessel's 12V or 24V power system. The compact 4-inch dial face (5 x 5 x 6 inches overall) fits standard marine instrument panels without requiring extensive modification. This gauge is essential for crews who operate in demanding conditions where engine failure translates directly to mission abort or safety risk.
