Tachometers

Tachometers – non-contact tachometer for rotational speed measurement

Tachometers are instruments used for the rapid measurement of rotational speed (RPM) of shafts and rotating components. In non-contact tachometer versions, measurements are taken without touching the moving parts, which enhances safety and facilitates machinery diagnostics in maintenance operations.

Application and characteristics of non-contact tachometers

A non-contact tachometer is ideal during inspections, commissioning, and drive operation monitoring when a fast and repeatable readout is required. Optical and laser solutions enable the rotation measurement of motors, gearboxes, fans, pumps, spindles, and other rotating components – without stopping the line and without interfering with the system.

In practice, tachometers are utilized to verify operating parameters, compare target and actual rotational speeds, and provide early detection of deviations that could indicate mechanical issues (e.g., slippage, incorrect gear ratio, or unstable drive operation). Depending on the model, features facilitating service measurements are available, such as HOLD, MIN/MAX value measurement, and readout memory.

Key advantages

• Non-contact rotational speed measurement – greater safety and convenience in diagnostics.
• Rapid RPM readout – efficient monitoring during inspections and commissioning.
• High repeatability – stable results even under varying rotational speeds.
• Optical / laser technology – easy measurement of hard-to-reach rotating components.
• Service functions – HOLD, MIN/MAX, and measurement memory (depending on the device).
• Compact design – convenient handling in industrial environments.
