Product Overview

The 9200‑03‑01‑02‑01 is a passive moving‑coil Seismoprobe velocity transducer built for absolute casing‑vibration measurement on rotating industrial machinery. It generates a proportional AC voltage output directly from mechanical motion, eliminating the need for external sensor power supplies. This side‑terminal variant features 90‑degree mounting orientation and 1/4‑20 UNC mounting stud for direct attachment to bearing housings, pump casings, fan assemblies and turbine support structures.

This transducer solves real‑world field challenges: reliable passive vibration acquisition for continuous monitoring or periodic route‑based data collection, reduced susceptibility to impulse shock compared to integrated solid‑state velocity sensors, and flexible wiring layout via side‑mount terminals for tight installation spaces. It feeds raw velocity signals to Bently Nevada monitoring hardware or portable vibration analysers; optional velocity‑to‑displacement converter hardware converts velocity readings into displacement values for machinery‑protection workflows. Rotating‑equipment reliability engineers, field‑service technicians and plant‑retrofit teams benefit most. Its sealed rugged housing suits general‑purpose heavy‑industry environments, and it serves as a drop‑in spare part for legacy machinery‑protection systems across power‑generation, oil‑gas and process‑manufacturing sites.

Key Application Notes

• Passive self‑generating sensor; requires monitor‑side input termination load of 10 kΩ for rated sensitivity
• Side‑located terminal block simplifies cable routing where top‑exit cabling is mechanically restricted
• Maximum cable run length 305 m; long cable runs introduce measurable high‑frequency signal attenuation
• Not suitable for shaft‑relative proximity measurement; intended for housing absolute‑vibration monitoring
• Mechanical installation must maintain specified mounting angle to preserve published measurement accuracy
• Compatible with 3300 series monitors, portable vibration analysers and 9513 velocity‑displacement converter modules
