990-04-XX-01-01 MOD:165335-01 Bently Nevada Transmitter
990-04-XX-01-01 MOD:165335-01
990-04-XX-01-01 MOD:165335-01 is an officially documented modified Bently Nevada 990 vibration-transmitter configuration. Baker Hughes document 141612 Rev. Y identifies 165335-01 as the 4140 / 3300 XL 8 mm / 9.0 m modification and states that the published 990 specifications also apply. 990-04-XX-01-01 MOD:165335-01 converts the compatible external transducer-chain signal to a proportional two-wire 4-20 mA output. The 3300 XL 8 mm probe and cable chain are external components unless the quotation for 990-04-XX-01-01 MOD:165335-01 explicitly includes them.
Scope note: 990-04-XX-01-01 MOD:165335-01 identifies modified loop-powered vibration transmitter. Complete-system performance is labeled separately and does not apply to 990-04-XX-01-01 MOD:165335-01 alone.

990-04-XX-01-01 MOD:165335-01 is limited to the officially documented 165335-01 modification. 990-04-XX-01-01 MOD:165335-01 must not be described with the standard 3300 NSv chain.
990-04-XX-01-01 MOD:165335-01 contains the transmitter electronics, while the documented external 3300 XL 8 mm probe and cable chain remain separate unless explicitly included in the quotation.

Compatibility statements are limited to the cited manufacturer documentation. Availability, condition and substitution must be confirmed separately.
990-04-XX-01-01 MOD:165335-01 is an officially documented modified Bently Nevada 990 vibration transmitter with modification 165335-01.
990-04-XX-01-01 MOD:165335-01 is configured for 0-4 mil pp (0-100 um pp) peak-to-peak vibration.
990-04-XX-01-01 MOD:165335-01 uses the official 165335-01 modification for an AISI 4140 target, a 3300 XL 8 mm transducer chain and 9.0 m system length.
990-04-XX-01-01 MOD:165335-01 is the transmitter configuration; the compatible 3300 XL 8 mm probe and cable are external components unless the quotation for 990-04-XX-01-01 MOD:165335-01 explicitly includes them.
990-04-XX-01-01 MOD:165335-01 requires +12 to +35 Vdc at the transmitter and 990-04-XX-01-01 MOD:165335-01 supplies a proportional two-wire 4-20 mAdc output.
990-04-XX-01-01 MOD:165335-01 drives the loop below 3.6 mA within 100 us after a Not OK condition and 990-04-XX-01-01 MOD:165335-01 restores the output about 2-3 seconds after the condition clears.
990-04-XX-01-01 MOD:165335-01 provides a non-isolated PROX OUT signal; Baker Hughes recommends the 122115-01 test adapter when grounded AC-powered test equipment is connected to 990-04-XX-01-01 MOD:165335-01.
990-04-XX-01-01 MOD:165335-01 provides vibration trending and loop alarming, but 990-04-XX-01-01 MOD:165335-01 does not provide the complete diagnostic and protection functions of a continuous monitoring system.
