What is a Non-contact tachometer?

Non-contact tachometers are used to measure the rotation of rotating equipment in industrial equipment. Rotating equipment is measured by various things, but it is very important because the rotation of the equipment may determine the capacity of the equipment. However, when it is not necessary to constantly monitor, it is troublesome to measure with a contact tachometer one by one, and it is dangerous when rotating at high speed. Therefore, a non-contact tachometer that can easily measure is used for performance tests of rotating equipment. There are various types, from handy type to permanent type.

Application of Non-contact tachometer

The number of revolutions is very important for equipment that uses a motor. For example, in the case of a roots blower, its ability is required from the number of revolutions, so it is necessary to perform a performance test before the customer-shipped test. At that time, a non-contact tachometer is used to measure the number of revolutions. Basically, such equipment does not need to be constantly monitored, so a non-contact type is sufficient. However, non-contact type is preferred even for equipment that requires constant monitoring. This is because if it is a contact type rotation speed, accurate rotation speed cannot be detected due to wear due to long-term specifications.
