Detailed Technical Specifications of the 990-05-XX-01-00 MOD：289549-17
Model decoding – 990 = Vibration Transmitter series. 05 = full‑scale range of 0‑5 mils pp (0‑125 µm pp). XX = system length to be specified (50 = 5 m, 70 = 7 m). 01 = DIN‑rail mounting clips. 00 = non‑hazardous area (no agency approvals). MOD: 289549‑17 = factory‑applied modification code – this typically indicates a specific calibration variant, configuration adjustment, or custom parameter set applied at manufacture.
General – Two‑wire, loop‑powered vibration transmitter designed primarily for OEMs of centrifugal air compressors, small pumps, motors, and fans. Accepts input from a Bently Nevada 3300 NSv proximity probe and matching extension cable (available in 5 m or 7 m system lengths). Conditions the signal into peak‑to‑peak vibration amplitude engineering units and provides a proportional 4‑20 mA industry‑standard signal to a control system for machinery protection alarming and logic. Integrated Proximitor Sensor requires no external unit.
Electrical specifications – Input: accepts one non‑contacting 3300 NSv proximity probe and extension cable. Power: requires +12 to +35 Vdc at the transmitter terminal. 4‑20 mA signal output over specified full‑scale range in two‑wire configuration. 4‑20 mA loop accuracy: within ±1.5% over full‑scale range, rated from TEST signal input to voltage measured across a 250 Ω load; this error is in addition to the Prox Out Incremental Scale Factor. Maximum loop resistance: 1,000 Ω including cable at 35 Vdc. Current limiting: 23 mA typical. Zero and span: non‑interacting external adjustments. Not OK/Signal Defeat: signal drops below 3.6 mA within 100 μs after a Not OK condition; restored within 2‑3 seconds after removal. Power‑up inhibit: output stays below 3.6 mA for 2‑3 seconds after power is applied. Prox Out output impedance: 10 kΩ, calibrated for a 10 MΩ load. Prox Out linear range: 1.4 mm (55 mils), beginning at approximately 0.25 mm (10 mils) from target. Prox Out incremental scale factor: 7.87 mV/μm (200 mV/mil) ±6.5% typical including interchangeability errors; worst case ±10%. Frequency response: 5 Hz to 6,000 Hz +0, –3 dB. Minimum target size: 9.5 mm (0.375 in) diameter.
Mechanical specifications – Transducer tip material: Polyphenylene sulfide (PPS). Transducer case material: AISI 303 or 304 Stainless Steel. Probe cable: 75 Ω coaxial, FEP insulated. Cable armor (optional): flexible AISI 302 SST with optional FEP outer jacket. Tensile strength: 222 N (50 lbf) probe case to probe lead, maximum. Transmitter weight: 0.43 kg (0.9 lbm). Total system weight: 0.82 kg (1.8 lbm) typical. Maximum thread engagement: 1/4‑28 = 0.375 in; 3/8‑24 = 0.563 in; M8×1 = 12 mm; M10×1 = 15 mm. Exceeding these limits may cause binding during installation and voids warranty.
Environmental limits – Transmitter operating temperature: –35 °C to +85 °C (–31 °F to +185 °F). Transmitter storage temperature: –52 °C to +100 °C (–62 °F to +212 °F). Probe operating and storage: –52 °C to +177 °C (–62 °F to +351 °F). Relative humidity: 100% condensing, non‑submerged, with protection of coaxial connectors. Potted construction provides protection in high‑humidity environments.
Certifications – FCC Part 15 compliant. EMC: EN 61000‑6‑2 and EN 61000‑6‑4, EMC Directive 2014/30/EU. RoHS Directive 2011/65/EU compliant. China RoHS: EFUP designation of 15 years per SJ/T 11364‑2024. Maritime: ABS 2009 Steel Vessels Rules. Note: the 00 agency option indicates this unit is supplied without hazardous area approvals – for Division 2, ATEX Zone 0/2, or maritime approvals, option 05 would be required.
Special features – Non‑isolated PROX OUT and COM terminals plus a coaxial connector provide dynamic vibration and gap voltage signal output for diagnostics. Non‑interacting zero and span potentiometers under the transmitter label support loop adjustment. Test Input pin allows quick verification of loop signal output using a function generator. Not OK/Signal Defeat circuit prevents high outputs or false alarms due to a faulty proximity probe or loose connection. Choice of DIN‑rail clips or bulkhead mounting screws simplifies installation. Integrated Proximitor Sensor eliminates the need for a separate external unit.
MOD: 289549‑17 – This modification code is a factory‑applied identifier that typically denotes a specific calibration configuration, custom parameter set, or application‑specific tuning applied to the base 990‑05‑XX‑01‑00 transmitter. While the exact nature of modification 289549‑17 is not detailed in the publicly available datasheet, such MOD codes are commonly used by Bently Nevada to indicate variants for particular target materials, system length combinations, or special performance adjustments. For precise details on this specific modification, consult the factory calibration certificate or contact Bently Nevada technical support with the full part number and MOD code.
