An electronic tachometer uses a magnetic pickup positioned near a rotating engine part to produce electrical pulses at a frequency proportional to the engine speed. Circuitry in the meter converts the pulse frequency for the display of engine RPM using a digital readout. Most manual or automatic transmission cars have a tachometer. While not required, of all the gauges in a boat , a tachometer is one of the more important ones due to its ability to help avoid unnecessary wear and tear and detect engine speed issues before things get worse.
Overall, a tachometer is a very useful instrument that can help you maintain optimal engine speed. KUS manufactures analog and digital tachometers for vehicle and marine applications.

Whereas, it is applicable for equipment like conveyors, windmill, rotary feeders, grinders, dryers, augers, elevators, etc. And the suitable industries include power plants, recycling and chemical plants, automotive and material handling, food and beverage, paper mills, etc. Now, ensure the safety of your equipment and automobile by measuring the working speed of an engine and maintaining the safe speed range with the help of a tachometer.
Tachometer What is Tachometer and its uses? Priya Tiple. Working Principle of Tachometer: An Electric Tachometer works on the principle of relative motion between the magnetic field and shaft of the coupled device. Types of Tachometer: Contact type — This type of tachometer is usually fixed to the machine or electric motor. It works by bringing a freely spinning wheel in contact with a rotating shaft or disc.
The shaft drives the wheel to generate the pulses. These pulses are then read by a tachometer and measured in revolution per minute. It can also calculate the linear speed and distance. Non-contact type — It is also known as photo tachometer or non-touch tachometer. It uses a laser, infrared light, or other light sources to take the measurements. The device sends out the beam of light.
This beam reflects each time a tape makes a full rotation. The receiver needs to count these reflections during the process to measure the rotational speed in RPM. This type of tachometer is efficient, durable, accurate, and compact.
Electronic tachometer — It is made up of electronic components used to measure the engine speed. It measures the speed in revolution per minute. It is mainly used in the dashboard of the car to measure the driving speed. It uses a magnetic pickup placed near a rotating engine to generate electric pulses. These pulses have frequency proportional to the engine speed. Analog tachometer — It is an electronic instrument that counts machine revolution based on time period.
