How to choose Shaft alignment devices

Points to check when selecting, with the values for this product (TKSA 11).

  1. 1. Measuring distance to suit shaft spacing

    This product: Measurement Distance 0 – 185 mm (between brackets)

    Measurement is not possible if the distance between the measuring units exceeds the instrument's measuring range. Estimate the mounting spacing of the two units across the coupling, and for long spacer shafts or large machines choose a model with ample margin under its upper limit.

  2. 2. Measurement error against required accuracy

    This product: Measurement Error Less than 2% / 10 μm

    Measurement error is often stated as a combination of a percentage and a fixed value (μm), and the error band increases as the measured value grows. For equipment with small permissible misalignment, such as high-speed rotating machines, confirm that the error is sufficiently small relative to the allowable value.

  3. 3. Checking the required rotation angle

    This product: Minimum Shaft Rotation Angle 180 °

    Among the listed products, the minimum shaft rotation angle required for measurement varies from 40° to 180°. For equipment where it is difficult to rotate the shaft half a turn due to piping or surrounding structures, a model that measures with a smaller rotation angle is suitable.

  4. 4. Shaft diameter and coupling height

    This product: Applicable shaft diameter 20～160 mm

    Confirm the shaft diameter that can be fitted with standard brackets and the coupling height that standard rods can clear (55 mm in the listed example). For large-diameter shafts or large couplings, check whether extension chains (up to 320 mm) or extension rods (up to 175 mm) are available.

  5. 5. Sensor type and operating device

    This product: Sensor method and communication Inductive proximity sensor ×2, electronic inclinometer, Bluetooth 4.0 LE

    The type of detection sensor and the wireless communication method affect measurement stability and how the instrument is operated. Choose between a dedicated display unit and an app on a personal smartphone or tablet, and check whether bringing such devices to the site is restricted.

  6. 6. Site environment and portability

    This product: Protection Rating (IP) Measuring unit IP54 (probe IP67)

    For outdoor sites or locations with water or dust, check the protection rating and operating temperature range. Total mass including the case ranges from 2.1 to 12.5 kg, and trolley-case models that include brackets are heavier, so select based on how the instrument will be transported.
