Electronic tachometers Manufacturers online

Electronic tachometers are devices for measuring the speed of rotating machines or components, such as motors, turbines or shafts.

They record the speed in revolutions per minute (rpm) or in frequency (Hz) and are used in many areas, e.g. in the automotive industry, mechanical engineering or maintenance.

Below you will find how they work, the most commonly used measuring methods and the areas of application of electronic tachometers, as well as their advantages and important aspects of their use:

How electronic tachometers work:

1. An electronic tachometer measures the number of revolutions of a rotating axle per minute.
2. It uses sensors such as optical, magnetic or inductive sensors to detect the movement and convert it into electrical signals.
3. These signals are evaluated by the electronics in the tachometer and output as a number on a display.

Measuring methods of electronic tachometers:

1. Optical: A laser or light source detects reflected light signals from markings on the rotating component.
2. Magnetic: A magnetic field sensor detects changes in the magnetic field in the vicinity of a rotating part (e.g. a toothed disk).
3. Inductive: The sensor generates electrical signals through the induction of currents by magnetic changes.

Areas of application for electronic tachometers:

1. Automotive industry:
monitoring engine speed to control performance and efficiency.

2. Mechanical engineering:
Checking the speed of machine components to monitor operating conditions.

3. Maintenance and servicing:
Measuring wear or signs of irregularities in drive shafts or motors.

4. Research:
Acquisition of precise rotation data for scientific or industrial tests.

Advantages of electronic tachometers:

• High precision: accurate measurement even at high rotational speeds.
• Versatility: Can be used in different industries and environments.
• Fast response time: Displays speed changes in real time.
• Compact design: Portable models allow use on various machines.

Use of electronic tachometers:

• Installation: a tachometer is either permanently mounted on the machine or used as a portable device.
• Measurement: The device must be correctly aligned with the rotating shaft or component in order to record precise values.
• Calibration: Before use, the tachometer should be calibrated to ensure accurate results.
• Data display: Tachometers display results in either digital or analog format. With modern devices, the data can also be stored or transmitted.

Electronic tachometers are indispensable tools in industrial and technical applications, as they provide reliable and precise information about the rotational movement of machines.

Here you will find the most important aspects to look out for when buying electronic tachometers:

When purchasing an electronic tachometer, several factors should be considered to ensure that the device is suitable for its intended use.

• Choose a tachometer whose measuring range matches the application. Make sure that the maximum speed of the device to be measured is within the range of the measuring device.
• The measuring accuracy should be high enough to provide precise values, especially in applications where small fluctuations are important.
• An optical sensor is ideal for clean environments where the speed can be measured via reflected light signals.
• Magnetic or inductive sensors are better suited to harsh environments as they are less susceptible to dust or dirt.
• Some models offer the option of using different sensor types (e.g. optical, inductive) to cover different application requirements.
• Digital tachometers offer a more precise and faster display, while analog displays are easier to read.
• Choose a device with an easy-to-read display, especially if it is used in poorly lit environments.
• For long-term monitoring, it can be useful if the tachometer stores the data.
• Some devices offer a USB or wireless interface to transfer the data to computers or other systems for analysis.
• A high resolution is required for applications where even the smallest changes in speed need to be recorded.
• Deviations in measurement accuracy (e.g. ±0.1% of the measured speed) should be taken into account in order to obtain reliable results.
• The tachometer should be robust enough to function reliably in industrial or harsh environments (e.g. high temperatures, humidity, vibrations).
• For use in harsh environments, the device should have at least an IP65 or IP67 certification to be protected against dust and water.
• Portable tachometers should be lightweight and easy to handle, especially when used in different locations or machines.
• The device should be easy to use and ready to use quickly without complex settings.
• If the tachometer is battery-powered, it should have a long battery life to allow for longer measurements.
• Pay attention to whether the device has replaceable or permanently installed rechargeable batteries.
• Check whether the tachometer has brackets or adapters for easy installation on machines.
• The price should be in proportion to the required functions and quality. More expensive devices often offer greater accuracy, robustness and additional functions such as data storage and transmission.
• Pay attention to the warranty and the availability of technical support.

By considering these aspects, you can ensure that the electronic tachometer will meet the requirements of your specific application and provide accurate measurements.
