The Bently Nevada 9200-06-05-10-00 is a high-precision Seismoprobe Velocity Transducer designed for continuous machinery protection and condition monitoring. Specifically engineered to measure absolute vibration of bearing housings, casings, or structural supports, this two-wire transducer operates on moving-coil technology. It provides a voltage output directly proportional to the vibration velocity, allowing operators to detect mechanical imbalances, misalignment, or bearing defects before they lead to catastrophic equipment failure. Its rugged design ensures reliability in harsh industrial environments, making it a critical component for steam turbines, pumps, and motors.

The model number 9200-06-05-10-00 follows a specific configuration structure defined by Bently Nevada to match site-specific mounting and environmental requirements:
9200: Product Series (Standard Seismoprobe Velocity Transducer).
06: Mounting Hardware Option. Refers to the specific stud size and mounting configuration (typically a 5/8-18 UNF stud for this variant).
05: Connector Option. Indicates the type and orientation of the electrical connector, ensuring compatibility with standard industrial 2-pin cables.
10: Agency Approval Option. Specifies the certification for hazardous areas; "10" typically denotes multiple approvals (e.g., CSA, ATEX, and IECEx) for intrinsic safety.
00: Reserved/Special Option. Standard factory configuration with no special modifications or custom labeling.
Proper installation is paramount for signal integrity. Please adhere to the following professional guidelines:
Surface Preparation: The mounting surface must be flat, smooth (63 micro-inch finish or better), and perpendicular to the axis of vibration.
Mounting Orientation: The 9200-06 is designed for Vertical mounting. Deviation from the specified 0° ±2.5° angle can lead to internal friction and inaccurate readings.
Torque Specifications: Use a calibrated torque wrench to tighten the transducer. Over-tightening can damage the casing, while under-tightening results in signal attenuation at high frequencies.
Wiring:
Pin A: Signal (High)
Pin B: Common (Low)
Shielding: The cable shield should be grounded at the monitor end only to prevent ground loops. Ensure the cable is secured with conduit or clips to prevent "cable whip" which introduces noise.
Q: Can I use the 9200-06-05-10-00 for horizontal vibration measurements?
A: No. This specific model is calibrated for vertical orientation. For horizontal measurements, the 9200-01 or 9200-02 variants should be used to account for internal spring bias.
Q: Does this transducer require external power?
A: No, the 9200 is a self-generating moving-coil sensor. It converts the mechanical energy of the vibration into an electrical signal without the need for an external power supply.
Q: What is the typical lifespan of the sensor?
A: Under normal operating conditions and within temperature limits, these sensors are designed for years of continuous service. However, high-impact shocks or extreme heat can degrade the internal damping fluid and springs.
