The 9200-06-05-10-00 functions as a velocity seismoprobe within the Bently Nevada 9200 series. This two-wire sensor measures absolute casing vibration on pumps, motors, and cooling tower fans. Its moving-coil design generates a voltage signal proportional to vibration velocity.

Signal Path and Interface Details
The sensor generates its own voltage as the internal coil moves through a magnetic field. Subsequently, this signal travels directly to a monitor or transmitter without conditioning. Because the design needs no external excitation, field wiring stays remarkably simple. The 9200-06-05-10-00 therefore suits remote installations where power is unavailable.
Energy Storage and Power Draw
This sensor contains no battery or storage capacitor of any kind. It relies on electromagnetic induction from vibration to produce its output. Consequently, power consumption remains zero during normal operation. System designers only need to account for the connected monitor’s input impedance.
Installation Notes
Operators mount the seismoprobe directly on the machine casing with a stud. The measurement axis must align with the direction of dominant vibration. Meanwhile, the IP67 enclosure tolerates dust, water spray, and washdown. Always route the cable away from high-current conductors.
