Tachometers play a vital role in monitoring machine performance and ensuring safety across various industries in NZ. Also known as a rev counter, a tachometer accurately measures rotational speed, allowing you to assess the performance of motors, engines, and other rotating machinery. This helps identify potential issues, optimise efficiency, and prevent costly downtime.

Additionally, a tachometer can alert you to potentially dangerous overspeed or underspeed conditions. Whether the tool displays the revolutions per minute (RPM) via an analogue dial or digital display, a tachometer can help you identify wear and tear on rotating components, allowing for timely maintenance and preventing premature failure.

To learn more about this tool, check out our [guide to tachometers](https://nz.rs-online.com/web/content/discovery/ideas-and-advice/tachometers-guide).

## **Types of Tachometers**

Tachometers are broadly classified into two main types based on their measurement methods:

### **Contact Tachometers**

Contact tachometers require physical contact with the rotating object to measure its speed, and they typically use a probe, wheel, or tip that comes into contact with the rotating surface. The probe or tip senses the rotational speed and transmits the data to the tachometer, which displays the RPM reading. Additionally, contact tachometers are suitable for applications where direct contact with the rotating object is possible and safe.

### **Non-contact Tachometers**

Non-contact tachometers, on the other hand, measure rotational speed without any physical contact with the rotating object. Also, they use lasers or optical sensors to detect the movement of the rotating object and calculate its speed, making them ideal for situations where contact is impractical or unsafe, such as measuring the speed of rotating fan blades or shafts. They are also well-suited for mobile applications where portability is important.

## **Features of Digital Tachometers**

Digital tachometers offer a range of features that enhance their functionality and usability. When choosing a digital tachometer in NZ, consider these features:

- **Display:** Digital tachometers typically feature LCD or LED displays that provide clear and easy-to-read RPM readings. Some models may also include backlights for improved visibility in low-light conditions.
- **Measurement Range:** Different digital tachometers offer different measurement ranges, so it's important to choose one that suits your specific needs. Also, consider the maximum RPM you need to measure and select a tachometer with an appropriate range.
- **Accuracy:** The accuracy of a digital tachometer is crucial for reliable measurements, so look for models with high accuracy ratings. While at it, consider any potential factors that may affect accuracy, such as environmental conditions or the type of surface being measured.
- **Portability and Compactness:** The size and portability of a digital tachometer can be important considerations, especially if you need to take measurements in different locations or in tight spaces. Depending on your needs, look for models that are lightweight, compact, and easy to handle.

## **Applications of Tachometer**

Tachometers are versatile tools used in a wide range of industries and applications, including:

- **Machinery:** In industrial settings, tachometers are essential for monitoring the rotational speed of motors, pumps, conveyors, and other machinery. This helps ensure efficient operation, identify potential issues, and prevent costly downtime.
- **Automotive:** Tachometers are commonly used in vehicles to measure engine RPM, providing drivers with information about engine performance and helping them optimise gear shifting and fuel efficiency.
- **Trains:** Tachometers play a crucial role in train maintenance and safety, monitoring the rotational speed of wheels, axles, and other critical components.
- **Laser Instruments:** Tachometers are used in laser instruments to measure the rotational speed of laser beams or scanning mirrors, ensuring accurate and consistent performance.
- **Laboratories:** In laboratory settings, tachometers are used to measure the speed of centrifuges, mixers, and other laboratory equipment, ensuring precise and controlled experiments.
- **Marine Engineering:** Tachometers are vital for monitoring the rotational speed of propellers, shafts, and other marine equipment, ensuring the safe and efficient operation of vessels.
- **Medicine:** In medical applications, tachometers are used to measure blood flow and other physiological parameters, providing valuable diagnostic information.
