Non contact measurement methods
The non-contact tachometer is designed with optoelectronic technology to measure fast and unmeasurable objects such as fans, motors, aircraft, propellers, cars.
- Apply a reflective marker to the object to be measured. (Note: the object to be measured must not be reflective)
- Install the battery, press the power on button and then press the test button.
- Aim at the reflective paper of the measured object to measure, and the value can be obtained.
Digital tachometers are commonly used in various industrial and automotive applications where it is necessary to measure the rotational speed of a shaft or engine. They are often used in manufacturing plants for quality control and monitoring purposes, as well as in the automotive industry for engine testing and tuning. Digital tachometers can also be found in marine and aviation industries, where they are used to monitor the speed of propellers and turbines. Additionally, they are often used in research and development settings, such as in wind tunnel testing and in the development of new engines and machinery.
Tips: Do digital tachometers require calibration?
Yes, digital tachometers do require calibration to ensure accurate readings. Calibration is the process of adjusting the instrument's output to match the expected or known values.
Digital tachometers are used to measure the rotational speed of a machine or engine, and their accuracy is crucial for ensuring proper operation and maintenance. Over time, the electronic components of the tachometer may drift or become less accurate, leading to incorrect readings. Therefore, periodic calibration is necessary to maintain the accuracy of the instrument.
Calibration of a digital tachometer involves comparing the readings of the tachometer against a reference standard, such as a calibrated generator or a frequency counter. The calibration process adjusts the tachometer's circuitry to ensure that it provides accurate readings across its entire range of measurements.
It is recommended to calibrate digital tachometers at least once a year or more frequently depending on the usage and environmental conditions. It's important to follow the manufacturer's recommended calibration procedures and use appropriate test equipment to ensure accurate and reliable results.
