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.
