Direct attachment seismic velocimeter transducer for vibration monitoring in rotating machinery
Seismic measurement of vibration velocity on rotating machines.
The T1-40 is a direct-attached seismic velocimeter transducer designed for precise measurement of vibration velocity on rotating machinery such as pumps, motors, compressors and fans.
Thanks to its advanced moving coil and permanent magnet technology, the sensor provides an analog signal directly proportional to the detected vibration, and can be interfaced with instruments such as TR-V, TRAL-V and TDSP.
Main applications
-
Vibration monitoring on rotating machinery (fans, pumps, compressors, motors).
-
Vibration analysis for predictive maintenance activities.
-
Reliable solution for industrial environment with direct installation.
Operation and compatibility
-
The transducer consists of a coil suspended by foils and a permanent magnet that generates the magnetic field.
-
It is mechanically fixed at the measuring point, generating a voltage proportional to the vibration velocity.
-
Compatible with various vibration analysis equipment in the T range.
