Tachometer Calibration

Tachometer is a smart electronic device commonly used in measuring and displaying the rotation speed of a particular object. It plays an extremely important role in ensuring the performance and safety of machines. Therefore, Tachometer Calibration is an essential activity to support the production process. Nowadays, there are many types of tachometer in the market such as: contact tachometer, non-contact tachometer, … In this blog, let’s learn more about the Tachometer Calibration process at Techmaster company.

What is Tachometer?

Rotation speed is one of the most important factors to help evaluate the quality of the movement in mechanical equipment. It is necessary to check the rotational speed, and people use a tachometer to do that.

Tachometer can measure the rotational speed of engines and machines accurately. This device is designed in a handheld form to be convenient for measuring many types of engine equipment. It is widely used in the inspection and evaluation of machine quality. As a result, people can easily detect and fix electronic devices to ensure their accuracy.

Types of Tachometer

Nowadays, there are many types of tachometers on the market, divided into a variety of product categories. Tachometer is usually classified in the most common way based on contact with the load and measurement method:

  • Contact Tachometer
Contact Tachometer
  • Non-contact Tachometer
Non-contact Tachometer
  • Frequency measuring

Equipment for tachometer calibration

When performing rev counter tachometer calibration, the following equipment should be prepared:
  • Frequency meter (Keysight 53220A)
  • Signal generator (Agilent 33250A)
  • Rubidium frequency standard (Pendulum 6689)
  • Contact type rotary speed calibrator (Tev RPMC-6000)
  • Auxiliary equipment: LED lights
  • Equipment to be calibrated (UUT): Contact and non-contact tachometers

Environmental conditions

Environmental conditions to be ensured when performing calibration:
  • Humidity: (40 ~ 70) %RH
  • Temperature: (20 ± 5) 0C

Process of Tachometer calibration

Calibration method: Compare the indication of the UUT with the standard frequency measurement system. Determine the UUT setting time accuracy.

Contact Tachometer

– Connect standard equipment system.

– Connect the UUT to the rotary shaft of the speed generator.

– Calibration in turn at points according to the procedure

– Export results.

Non-contact tachometer

– Connect standard equipment system.

– Put the UUT in the position suitable for the emitter

– Calibration in turn at points according to the procedure

– Export results.
