Bently Nevada 9200-06-02-01-00 Seismoprobe Velocity Transducer
The Bently Nevada 9200-06-02-01-00 is a two-wire moving-coil velocity seismoprobe transducer. Brand New, Original Stock with Global Shipping.
Description
Configured for absolute bearing housing, casing, or structural vibration measurements in industrial monitoring systems, the Bently Nevada 9200-06-02-01-00 (9200 Seismoprobe Velocity Transducer) provides direct physical/electrical execution. The two-wire architecture employs moving-coil technology to output a voltage signal directly proportional to the machine surface velocity without requiring external excitation power.

Machinery Monitoring and Diagnostic Attributes
The instrument incorporates a moving-coil mechanism that directly scales voltage output against machine casing velocity vectors. During structural tracking, this inner self-generating system validates raw dynamic velocities while bypassing the gap voltage validation limits (-10 VDC targets) characteristic of proximity probes. Furthermore, internal physical damping rules suppress transient cross-talk and impact excitations, which allows the element to output pure rotor dynamics data straight to a standard machinery protection monitor or portable diagnostic tool.
Frequently Asked Questions
Q: How does the internal physical orientation change affect the electrical sensitivity?
A: Installers must verify that the casing mounting angle stays within the 0 deg +/- 100 deg configuration limit. Operating the sensor outside this specific physical window causes the internal moving coil to drag mechanically, which severely degrades frequency response and calibration accuracy.
Q: Does the sensor require an external power supply or loop voltage to generate signals?
A: No. The internal electromagnetic moving-coil configuration relies entirely on structural velocity forces to induce the signal voltage across Pin A and Pin B, meaning it operates passively without external power inputs.
Field Installation Guidelines
First, prepare the machinery surface by machining a flat mounting spot matching the circular casing dimensions. Next, secure the integrated base stud into a 1/4-20 UNC-2B threaded hole, applying a mounting torque value of exactly 5.6 N-m to prevent any mechanical contact losses. Following this, route the 2-conductor shielded interconnecting cable through robust, grounded conduit systems away from high-voltage motor supply paths. Finally, terminate the outer cable shield directly to the designated machine casing ground point, which prevents ambient electromagnetic noise from corrupting the low-level differential voltage output.
