Features:
- True Absolute Vibration Measurement Without External Power
- Universal ±180° Mounting Orientation with 15 Hz Low-Frequency Cutoff
- Industrial-Grade Environmental Protection with Direct Monitor Compatibility
The Bently Nevada 9200-09-01-02-00 utilizes passive moving-coil technology that generates its own voltage output proportional to casing velocity. Unlike accelerometers requiring external excitation or integrated electronics, this self-generating design eliminates power supply failure risks and simplifies field wiring. The 20 mV/mm/s sensitivity provides direct velocity output without integration or differentiation, reducing signal processing errors and improving measurement fidelity for machinery protection systems.
The Bently Nevada 9200-09-01-02-00 features the Option 09 mounting configuration, allowing installation at any angle from vertical to horizontal without performance degradation. This flexibility is critical for retrofits or tight machinery spaces where vertical mounting is impossible. The 15 Hz (900 CPM) minimum operating frequency captures common rotor-dynamic faults including unbalance, misalignment, and looseness, while the 1 kHz upper range covers rolling element bearing defects and gear mesh harmonics.
Engineered for harsh industrial environments, the Bently Nevada 9200-09-01-02-00 operates reliably from -29°C to +121°C and withstands 50 g shock events common in reciprocating compressors and punch presses. The anodized aluminum housing resists corrosion without additional coatings, and the top-mounted connector (Option 01) simplifies cable routing. With direct compatibility to Bently Nevada 3300/3500 monitoring systems over cable runs up to 305 meters, this transducer integrates into existing protection architectures without signal conditioners or external converters.
The 9200-09-01-02-00 Bently Nevada Seismoprobe Velocity Transducer may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Rotating Machinery Casing Vibration Monitoring – The Bently Nevada 9200-09-01-02-00 is installed on bearing housings of pumps, motors, fans, and compressors to measure absolute casing vibration. This direct measurement captures unbalance, misalignment, and looseness — three faults responsible for over 60% of unplanned downtime in industrial rotating equipment.
- Rolling Element Bearing Fault Detection – With frequency response extending to 1 kHz, the transducer captures bearing defect frequencies including ball pass frequencies of inner/outer races and fundamental train frequencies. Early detection allows planned maintenance before secondary damage occurs to shafts or housings.
- Reciprocating Compressor Condition Monitoring – Unlike accelerometers that saturate under high shock, the moving-coil design of this transducer withstands 50 g impulses typical of reciprocating machines. It measures crosshead and crankcase vibration where impact events would otherwise drive electronic sensors into non-linear ranges.
- Portable Data Collection for Predictive Maintenance – When paired with a magnetic base (Bently accessory 46000-01), the transducer serves as a portable spot-check tool. Maintenance teams can collect vibration data on hundreds of machines using a single sensor and handheld analyzer, ideal for facilities without permanent monitoring on every asset.
- Continuous Machinery Protection with 3300/3500 Systems – The transducer connects directly to Bently Nevada 3300 and 3500 rack-mounted monitors, providing 24/7 alarming against user-set velocity thresholds (e.g., alert at 6 mm/s, danger at 12 mm/s). The monitoring system can initiate shutdown sequences or alert operators before catastrophic failure.
- Integration with Plant DCS/PLC for Asset Management – Via the 3500 monitor's 4-20 mA outputs, the velocity signal transmits to distributed control systems (DCS) such as Emerson DeltaV, Honeywell Experion, or Siemens PCS 7. This allows vibration data to appear alongside process variables (pressure, temperature, flow) on operator consoles, enabling correlated diagnostics.
- Spectrum Analysis for Root Cause Diagnosis – The raw analog velocity output, when sampled at 2.56 kHz or higher, feeds into portable analyzers (e.g., CSI 2140, SKF Microlog) or online systems (System 1®). Operators can perform Fast Fourier Transform (FFT) to separate vibration sources — 1× running speed indicates unbalance, 2× suggests misalignment, and non-synchronous peaks point to bearing or gear faults.
- Route-Based Predictive Maintenance Programs – Using the transducer with a handheld data collector, reliability engineers execute monthly vibration routes across hundreds of assets. Trend analysis of overall velocity values (mm/s RMS) identifies degradation trajectories, allowing replacement scheduling during planned outages rather than emergency shutdowns.
- Wide Operating Temperature Range for Global Installations – The transducer functions from -29°C to +121°C, covering arctic outdoor compressor stations to indoor paper mill dryers. Below -29°C, sensitivity drifts -0.2%/°C — field calibration or temperature compensation in the monitoring system is required for accurate absolute readings.
- Humidity and Moisture Resistance Without Submersion – At 95% non-condensing humidity, the top-mounted connector remains operational. For 100% humidity or direct water spray (e.g., washdown areas), the integral cable option (not this configuration) provides sealed construction. Do not submerge the transducer — it is not rated for immersion.
- Shock Tolerance for High-Impact Machinery – Rated for 50 g peak shock on non-sensitive axes, the transducer survives hammer blows, reciprocating compressor firing pulses, and crusher impacts. For reference, 50 g is equivalent to a hard slap — sufficient for industrial environments without damage, unlike laboratory-grade sensors that fail above 10 g.
- Chemical Resistance for Corrosive Atmospheres – The anodized aluminum case (A204G) resists oxidation and corrosion in petrochemical, wastewater, and marine environments. Neoprene gaskets tolerate oil mist and mild acids. However, continuous exposure to strong solvents (acetone, MEK) or high-concentration acids will degrade the neoprene and connector materials — use a protective boot or housing in these cases.
