ABOUT TACHOMETER

A tachometer is a device connected to the crankshaft of an engine that measures its rotational speed. It resembles a sensor with a directional arrow and a scale. The majority of users of this device are drivers who enjoy driving quickly. On a manual transmission or an automatic transmission in manual mode, it is possible to "untwist" the engine to its maximum speed for optimal switching dynamics. Using a magnetic pickup placed near the engine's rotating crankshaft, an electronic tachometer produces electrical pulses at a frequency proportional to engine speed. An inductive proximity sensor is installed in the flywheel housing, and a magnet is attached to the flywheel. So every time the magnet rotates through the inductive sensor, a pulse is generated, which is then converted into an electrical signal and displayed on the tachometer.

TACHOMETER DESIGNS

There are a variety of tachometer types, including mechanical, analog, and electronic. The mechanical modification is utilized in vintage automobiles and motorcycles. In this case, the primary component is the cable. On the other hand, it is connected to the camshaft (or crankshaft). The opposite end is attached to the receiving mechanism located behind the device's scale. During shaft rotation, the central core rotates within the casing. Torque is transmitted to the gears that are connected to the arrow, setting it in motion. Typically, these devices are installed on low-speed motors, so the scale on them is divided into 250 rpm increments, whereas automobiles older than 20 years are fitted with analogue tachometers. Modern economy vehicles come equipped with advanced features. This modification is visually very similar to the previous one. It also has a circular dial with a moving arrow. Analog tachometers are a more advanced variant. The principle of transmitting torque to the arrow drive differs from the previous modification, despite the fact that the exterior resembles its predecessor. The device's electronic component is connected to the crankshaft position sensor. Inside the tachometer is a magnetic coil that deflects the needle by the required amount. These tachometers also have substantial errors.

Lastly, the electronic tachometer device is regarded as the most precise. They contain a greater number of components than the previous options. The most recent evolution of tachometers is the digital variety. The turnover rate can be represented by glowing numbers. In more advanced models, the screen displays a virtual dial with an arrow. This device is connected to the crankshaft sensor as well. However, rather than a magnetic coil, a microprocessor is fitted in the tachometer unit, which recognizes the sensor signals and outputs the corresponding value. These devices have the smallest error rate, approximately 100 rpm.
