200155-09-05 | Bently Nevada Low Frequency Accelerometer

The Bently Nevada 200155-09-05 is a Connector for industrial control and automation applications.

Bently Nevada 200155-09-05 is a Low Frequency Trendmaster Pro accelerometer designed for precise vibration measurement on fin-fan and slow rotating shafts. Its 10.2 mV/(m/s2) sensitivity at 80 Hz and ±196 m/s2 measurement range deliver reliable data for condition monitoring.

What makes the 200155-09-05 accelerometer cost-effective for slow-speed machinery?

This unit combines a wide frequency range of 1.5 to 10,000 Hz with a hermetic 316L stainless steel housing. This design reduces unplanned downtime by enabling early fault detection on critical assets. The multiple approvals (CSA, ATEX, and IECEx) simplify deployment in regulated environments, avoiding costly recertification. With a settling time of ≤2000 ms and quiescent current <800 µA, it integrates efficiently into Trendmaster Pro systems, lowering installation and operating expenses.

Key technical parameters and their cost implications

• Sensitivity: 10.2 mV/(m/s2) (100 mV/g) at 80 Hz (±12%) – ensures accurate signal capture, reducing false alarms and maintenance costs.
• Measurement Range: ±196 m/s2 (±20 g) – accommodates high-amplitude vibrations without clipping, extending sensor life.
• Frequency Range: 1.5 to 10,000 Hz (90 to 600,000 cpm) – covers low-frequency events on slow rotating shafts, preventing missed faults.
• Temperature Range: -40 °C to +105 °C (-40 °F to +221 °F) – operates in harsh conditions, minimizing environmental protection costs.
• Mounting Stud: 3/8-24 to 3/4 NPT, 1-1/4 inch hex – simplifies installation, reducing labor time.

Each specification directly supports lower total cost of ownership through reliable performance and reduced maintenance interventions.

Installation and maintenance for reliable long-term operation

Mount This unit using the 3/8-24 female thread with a torque of 2.7 to 6.8 N·m (2 to 5 ft·lbf). The hermetic sealing (5X10-8 atm·cc/s maximum) and 100% relative humidity tolerance ensure durability in condensing environments. Regular inspection of the mounting stud and connector helps prevent signal degradation.
