4-137 is a vibration transducer that outputs a voltage signal proportional to the speed of vibration.
The 4-137 is a vibration transducer that outputs a voltage signal proportional to the velocity of vibration. Since the vibration velocity is proportional to the product of displacement and frequency, monitoring the vibration velocity allows for optimal detection of abnormalities in vibration. By using a special state-of-the-art bearing system, the usable time has been significantly extended. This vibration transducer is self-excited, has a high output level, and low output impedance, eliminating the need for special low-noise cables or charge amplifiers, thus simplifying the measurement system and enhancing reliability.
