Transducteur à deux fils Bently Nevada 9200-06-02-10-00

The 9200 standard velocity transducer, complete part number 9200-06-02-10-00, is a two-wire moving-coil transducer designed to measure absolute casing vibration on rotating machinery. The mechanical system features a wire-suspended coil moving around a permanent magnet, providing a voltage output directly proportional to vibration velocity. This self-generating sensor requires no external power and operates within a dedicated orientation window defined by its specific option configuration. The 9200 series utilizes rotor dynamics principles to continuously monitor structural casing movement, ensuring critical machinery protection and interfacing directly with Bently Nevada monitoring systems through low-impedance signal transmission.

Hardware Specifications

Engineering Notes

• Ensure the sensor installation angle precisely matches the 0 ±100° horizontal range specification to avoid physical internal coil binding against the magnet housing.
• Operating the transducer below the specified 10 Hz frequency limit causes significant amplitude attenuation and phase shift errors in velocity data.
• Cross-axis vibration sensitivity must be minimized by aligning the primary measurement axis directly parallel to the intended machinery vibration direction.
• The self-generating coil assembly introduces a fixed internal impedance that must be matched with compatible monitoring instrumentation inputs to prevent signal loading effects.

Field Guidelines

• Implement dedicated shield grounding protocols by connecting the cable shield at the monitoring rack end only, ensuring the transducer end remains isolated to eliminate ground loops.
• Maintain proper cable routing segregation by separating transducer signal lines from high-voltage AC power distribution conduits to reduce electro-magnetic interference.
• Avoid exceeding the minimum bending radius of the field wiring cable to prevent internal conductor damage or degradation of the insulation barrier.
• Verify the structural integrity of the M10X1 mounting surface, ensuring it is flat, smooth, and free of paint or debris to guarantee accurate high-frequency vibration transmission.
• Apply correct torque specifications when securing the circular mounting base to the machine casing to prevent resonant frequencies from distorting the velocity readings.

Technical & Procurement FAQ

Q: Can this 9200-06-02-10-00 model be mounted in a purely vertical orientation on a machine casing?

A: No, the -06 suffix designates a horizontal mounting configuration of 0 ±100 degrees; vertical mounting requires a different option code to calibrate the internal spring-coil alignment.

Q: What components are included inside the shipping box for this specific part number?

A: The package contains the brand-new original 9200-06-02-10-00 velocity transducer assembly with its integrated side-mount connector and M10X1 circular mounting base stud.

Q: Does this specific transducer module require a separate external power supply to output the velocity signal?

A: No, this is a self-generating electro-magnetic moving-coil sensor that produces its own voltage output relative to velocity without requiring external loop power.
