Piezoelectric velomitor transducer for absolute vibration control
Absolute vibration control with piezoelectric technology.
Models TV-22 and TV-32 are direct-attached piezoelectric velomitor transducers designed for the precise detection of absolute vibrations in rotating machinery.
Through the use of piezoelectric technology, they generate an electrical signal proportional to the speed of vibration, enabling real-time monitoring of plant operating conditions.
