TACHOMETER DIGITAL CONTACT/NON CONTACT

A tachometer is a device used to measure the rotational speed of a rotating object, typically expressed in revolutions per minute (RPM). They are used in various applications, including automobiles, aircraft, industrial machinery, and laboratory equipment, to monitor speed and prevent damage. 

Here’s a more detailed overview:

What it measures:
  • Rotational Speed:
    The primary function of a tachometer is to measure how fast a rotating shaft, disc, or other rotating part is turning. 

  • Units:
    The most common unit for rotational speed is RPM (revolutions per minute). 

  • Applications:
    • Automotive: In cars, tachometers indicate engine speed and can help drivers determine when to shift gears. 
    • Aircraft: In airplanes, tachometers monitor engine speed to ensure safe and efficient operation. 
    • Industrial Machinery: Tachometers are used in factories and power plants to monitor the speed of motors, pumps, and other machinery. 
    • Laboratories: They are used to calibrate the speed of centrifuges, grinders, and other equipment. 
  • Types:
    • Analog: Use a needle and dial to display the RPM. 
    • Digital: Display RPM on a screen, offering more precise readings. 
    • Contact and Non-Contact: Contact tachometers make direct contact with the rotating part, while non-contact tachometers use methods like lasers to measure speed without physical contact. 
Why it’s important:
  • Monitoring Speed:
    Tachometers help monitor the speed of rotating parts to ensure they are operating within safe and optimal ranges. 

  • Preventing Damage:
    By monitoring speed, tachometers can help prevent equipment damage caused by overspeed or underspeed conditions. 

  • Maintaining Efficiency:
    In engines, tachometers help maintain optimal speed for efficient fuel consumption and performance. 

  • Calibration:
    In laboratory settings, tachometers are used to calibrate the speed of equipment for accurate experimentation.
