The FT-2500 Advanced Tachometer by ONO SOKKI is an innovative solution that makes rotational speed measurement remarkably simple. It provides exceptional accuracy even when the rotating shaft cannot be accessed directly. Equipped with advanced FFT (Fast Fourier Transform) technology, it detects and calculates rotational speed from changes in sound, vibration, and magnetic fields generated by rotating machinery such as motors and engines. The FT-2500 can also calculate and display rotational speed from complex waveform signals captured by microphones, sound level meters, or vibration sensors by isolating the frequency components corresponding to the rotation speed with high precision.

Gain Clear Insight into Vibration Data with the FT-2500

In manufacturing, even the smallest deviation can lead to errors that affect both quality and cost. One of the most commonly overlooked factors is vibration, which occurs within machinery and components during actual operation. A tool that can capture deep and accurate vibration insights is no longer just an accessory—it becomes a critical element for decision-making related to efficiency, safety, and confidence in every stage of production.

Key Features

• High accuracy with fast response
Equipped with advanced digital measurement technology, the FT-2500 delivers extremely precise rotational speed detection—even during sudden changes in speed. It is ideal for testing motors, engines, and any equipment requiring high-resolution measurement.

• Supports multiple signal types
The device can connect to a variety of sensors, such as magnetic pick-ups and pulse signal sensors, providing flexible and convenient operation for different applications.

• Clear display and intuitive operation
Designed for ease of use, the digital display allows users to read data clearly. Simple configuration settings help reduce preparation time and improve workflow efficiency.

• Industrial-grade stability and durability
Manufactured under Japanese quality standards, the FT-2500 is built to withstand long-term use while maintaining accuracy even in demanding operating environments.

The FT-2500 can evaluate the rotational speed of components—such as motors embedded inside a product—without the need for reflective tape or direct sensor attachment. A newly developed algorithm enables accurate measurement during both steady-state and variable-speed rotation.

Application Examples

The FT-2500 from ONO SOKKI is widely used across various industries. Below are practical examples of how it can be used in production lines, quality inspection, and preventive maintenance.

■ Measuring the rotational speed of small-shaft DC motors
The FT-2500 can measure the speed of a DC motor without attaching reflective tape to the shaft—ideal for small fan motors whose shafts are too thin for reflective stickers. This enables simple, non-contact measurement, making it perfect for quality inspection processes.

■ Measuring the rotational speed of DC motors in fuel pumps using a current probe sensor
DC motors in automotive systems often draw current in a pulse pattern according to the number of poles. By inputting the current waveform obtained through a current probe sensor into the FT-2500, rotational speed can be measured accurately.

■ Measuring compressor rotational speed using an accelerometer
When paired with a suitable accelerometer, the FT-2500 can measure the speed of compressors in refrigerators, vending machines, or air conditioners—equipment where the compressor shaft cannot be accessed directly.

■ Measuring engine rotational speed using a microphone or vibration sensor
The FT-2500 can measure engine RPM by analyzing sound and vibration generated by piston movement. This is especially effective when the engine bay is covered or difficult to access, making direct sensor attachment impossible.

The FT-2500 is a highly capable instrument for research and development, as well as for high-precision quality inspection in industries that demand accurate rotational speed measurement.
