High-Temperature Two-Wire Seismoprobe Velocity Transducer
Bently Nevada 74712-06-12-04-04 is a high-temperature, two-wire Seismoprobe velocity transducer for absolute vibration measurement on bearing housings, machine casings and structural surfaces. Its self-powered moving-coil design produces a voltage proportional to vibration velocity and does not require external excitation. This exact configuration specifies a vertical calibration orientation with a 10 Hz minimum operating frequency, an isolated circular 1/2-20 UNF-2A mounting base, a side-mounted connector and ATEX/IECEx approval. It supports demanding machinery protection and diagnostic applications. Before replacement, verify the complete suffix, mounting surface, cable, monitor input, load, operating temperature, hazardous-area requirements and calibration orientation.
