OnoSokki - Model FT-7200 -Advanced Handheld Tachometer
The FT-7200 Advanced Tachometer is an easy-to-use handheld digital tachometer offering high functions and performance. The use of FFT (Fast Fourier Transform) technology enables the FT-7200 to perform frequency analysis of rotation speed by using change of signal in sound, vibration or magnetic flux from rotating machines such as a motor or the like. Selection from 5 kinds of measurement modes allows it to calculate and display rotation speed of any complex waveform signals from a sound level meter or an accelerometer accurately by extracting the exact frequency component.
The FT-7200 enables non-contact measurement of rotation speed by sound or vibration from a measurement object with inaccessible rotating shaft such as a built-in motor in a product, which disabled using conventional tachometers. No need for affixing a reflection mark or modification to a rotating shaft of a measurement object. Also the use of new algorithm allows calculation and displaying with high follow-up performance, even a sudden change of rotation speed in rising/falling edge of a motor or accelerated/decelerated engine rotation, which has been disabled with conventional models. The FT-7200 is a battery-operated and easy to carry handheld tachometer facilitating on-site measurement. The FT-7200 can be used with various optional detectors by Ono Sokki; microphone and sound level meter, accelerometer and engine vibration detector, ignition pulse detector and so on. In addition, the FT-0801 cigarette lighter socket sensor is available for detecting voltage output from power outlet in vehicle. Selectable from wide range of detectors depending on your requirements.
