Description

The Bently Nevada 200350-02-00, also cataloged as the 200350 Accelerometer, operates as a dedicated hardware component for high-frequency vibration measurement within machinery monitoring networks. The transducer measures dynamic acceleration forces across rotating machinery shafts, converting mechanical excitation into proportional electrical signals for online monitor evaluation.

Suffix Breakdown & Model Matrix

The 200350 accelerometer utilizes a standardized alphanumeric matrix configuration code defined as AA-BB-CC to specify physical mounting configurations and electrical tolerance limits.

• AA (Mounting Stud): Option 02 designates a 1/4-28 to M8 x 1.25 Stainless Steel threaded mounting stud.
• BB (Tolerance): Option 00 specifies a nominal scale factor sensitivity of 100 mV/g with a ± 20% tolerance band (equivalent to 10.2 mV/m/s^2 ± 20%).

Hardware Specifications

Machinery Monitoring & TSI Characteristics

The transducer supplies raw high-frequency waveforms directly to proximity and acceleration monitoring modules to track complex rotor dynamics. Furthermore, proper mechanical coupling directly impacts the eddy-current probe scaling metrics and high-frequency resonance tracking. Operating within predefined bias boundaries, the internal sensor circuitry enables continuous signal transmission over long distances while maintaining cross-talk suppression protocols inside adjacent multiconductor cable runs.

Frequently Asked Questions

Q: How does the choice of mounting stud affect the frequency response of the 200350-02-00 sensor?

A: The rigid 1/4-28 to M8 x 1.25 stainless steel stud ensures transmission of high-frequency components without attenuation, whereas adhesive or magnetic mounting bases introduce mechanical damping that limits high-frequency responsiveness.

Q: What power source does the 200350-02-00 require for standard operation?

A: The sensor operates as a constant-current device requiring a constant current source, typically supplied via the input channels of an external Bently Nevada monitor rack interface.

Field Installation Guidelines

• Prepare the machinery surface by machining a flat, smooth mounting spot free of burrs and paint to ensure complete physical contact.
• Apply the specified installation torque during thread engagement to prevent mechanical loose-contact artifacts from distorting dynamic vibration readings.
• Route the sensor cable away from high-voltage motor lines and ensure all cable shields terminate exclusively at the instrument common grounding terminal.
