Speed Monitors
12/23/2025

Tachometers are essential instruments for monitoring rotational speed (RPM) in engines, turbines, and industrial machinery. Over the years, these devices have evolved from simple RPM meters to advanced, feature-rich instruments designed to meet specific customer requirements. Barksdale's speed tachometers stand out for their rugged reliability, ease of installation, and customer-focused design.

Why Tachometers Matter

Accurate RPM measurement is critical for:

  • Preventing equipment failure through overspeed alarms.

  • Optimizing maintenance schedules with hour meters.

  • Diagnosing performance issues using peak RPM logs.

Dynalco tachometers simplify wiring by using pickup power, meaning you only need to connect the pickup wires—no external power source required.
