Hardware Specifications

Rotor Dynamics Phase Validation & Cross-Talk Suppression

The moving-coil internal architecture employs a suspended permanent magnet mass surrounded by a wire coil matrix to perform seismic mechanical measurements. During structural transient vibration tracking, the magnetic circuit generates a voltage directly proportional to casing velocity without external excitation fields. To preserve absolute signal integration fidelity and prevent rotor dynamics cross-talk, internal damping parameters limit transverse axis sensitivity to less than 10% of the active measurement axis at 100 Hz. The mechanical suspension prevents signal clipping or saturation caused by impulse shock forces up to 50 g peak along the non-sensitive transverse layout.

Frequently Asked Questions

Q: Does the 9200 moving-coil transducer require an external power supply or proximity driver unit?

A: No. The internal electromagnetic moving-coil architecture is entirely self-generating. The mechanical motion of the internal coil assembly cuts the magnetic flux lines of the static permanent magnet to produce the 20 mV/mm/s output signal directly across its output terminals without active semiconductor components or power networks.

Q: How critical is the exact orientation angle for the 9200-03-02-02-00 variation?

A: The "03" code specifies a vertical configuration optimized for 90 deg +/-2.5 deg operation relative to true horizontal alignment. Mounting this specific transducer outside of this mechanical angle envelope offsets the internal spring-mass center point, altering the low-frequency response thresholds and invalidating calibrated linearity.

Field Installation Guidelines

• Mechanical Torquing Bounds: Fasten the circular base to a clean, machined vertical mounting surface using the 1/4-in 28 UNF stud. Tighten the assembly to a specified mechanical torque of 5.6 Nm (50 in-lb) using a calibrated torque wrench to ensure rigid mechanical coupling to the casing.
• Twisted Pair Cabling Shields: Connect the side-mount pins to a 2-conductor twisted, shielded 22 AWG field cable. Route the shield conductor continuously through intermediate junction assemblies and terminate it exclusively at the 3300 or 3500 monitoring system chassis ground to arrest common-mode electrical noise.
• Conduit Entry and Drip Loops: Form an explicit physical drip loop in the terminal flexible conduit leading into the side connector assembly. Ensure the neoprene sealing gasket sits squarely inside the housing interface to prevent moisture ingress or environmental fluid contamination from destroying the internal silver-plated copper contacts.
