Tachometers are instruments designed to measure rotations in terms of revolutions per minute of a rotating shaft or motor. Contact tachometers come in compact sizes and offer accurate readings. These tachometers have an embedded microcontroller LSI Circuit. Contact tachometers are known for precise RPM measurement and easy to use. Their battery consumption is relatively low as compared to other tachometers such as non-contact tachometers. Non-contact tachometers measure the speed of rotating objects by using reflected visible spectrum light. Some of these contactless tachometers can work for contact style testing by using a contact adapter. Digital stroboscope tachometers are used to measure flash frequency velocity. These tachometers operate on 4 x 1.5 V AAA batteries. They are widely used in printing and textile industries.
