TV-22 TV-32
TV-22 and TV-32 transducers seismically measure absolute vibration by a direct installation on the supports of the vibrating part and supplies an output signal directly proportional to the vibration. This signal can subsequently be processed by a measuring channel of a CEMB “T” series device.
TV-22 and TV-32 transducers exploits the piezoelectric effect, generates an electric signal proportional to the vibration speed
