    Contact measurement methods

    contact measurement method

    Contact tachometers are equipped with different contact probes to enable reliable contact between the tachometer and the shaft to be measured.

    1. Contact measurement of motor bearing speed and linear speed.
    2. The contact probe is placed close to the object to be measured and is fixed at the same level as the motor bearing.
    3. The tachometer accessories are suitable for a wide range of applications.


    digital contact measurement details


    Digital tachometers are commonly used in various industrial and automotive applications where it is necessary to measure the rotational speed of a shaft or engine. They are often used in manufacturing plants for quality control and monitoring purposes, as well as in the automotive industry for engine testing and tuning. Digital tachometers can also be found in marine and aviation industries, where they are used to monitor the speed of propellers and turbines. Additionally, they are often used in research and development settings, such as in wind tunnel testing and in the development of new engines and machinery.

    Digital tachometers applications

    Tips: What are the different types of digital tachometers?

    A digital tachometer is a type of instrument used to measure the rotational speed of a shaft or disk in a machine or vehicle. There are several different types of digital tachometers available on the market, including:

    • Contact Tachometers: These tachometers use physical contact with the rotating object to measure its speed. They typically have a wheel or probe that is placed against the object, and they work by measuring the number of revolutions per minute (RPM) of the wheel or probe.
    • Non-Contact Tachometers: These tachometers use light or other electromagnetic waves to measure the rotational speed of an object without physically touching it. They typically use a laser or an infrared beam to detect the motion of the object and calculate its RPM.
    • Combination Tachometers: These tachometers combine both contact and non-contact measurement methods to provide more accurate and versatile measurement capabilities. They may have both a wheel and a laser or infrared sensor for more flexibility in different measurement scenarios.
    • Handheld Tachometers: These tachometers are portable and typically battery-powered, making them suitable for field measurements or applications where a stationary instrument is not practical.
    • Panel-Mount Tachometers: These tachometers are designed for installation in a control panel or dashboard and provide a continuous display of RPM for monitoring and control purposes.
    • Data-Logging Tachometers: These tachometers can record and store RPM data over time for analysis and troubleshooting. They may have built-in memory or allow for external data storage through a computer or other device.
