200155-18-05 | Bently Nevada 10.2 mV/(m/s2) Low Frequency Accelerometer

Introduction to the Bently Nevada 200155-18-05

When monitoring slow rotating shafts and fin-fan applications, the 200155-18-05 from Bently Nevada provides reliable low frequency vibration data. This Trendmaster Pro Accelerometer is designed for demanding industrial environments. Its high sensitivity and robust construction make it a trusted choice for condition monitoring.

Key Features and Technical Specifications

The 200155-18-05 offers a sensitivity of 10.2 mV/(m/s2) at 80 Hz. Its measurement range reaches ±196 m/s2 (±20 g). The frequency range spans 1.5 to 10,000 Hz (90 to 600,000 cpm). With a mounted resonant frequency above 20 kHz, it captures critical vibration data. Amplitude linearity stays within ±2% from 1 to 10 g pk. Transverse sensitivity is ≤7%. Settling time is ≤2000 ms. Excitation voltage ranges from 4.7 to 5.5 Vdc. Quiescent current is below 800 µA. Output bias voltage is +2.5 ± 0.23 Vdc. The ceramic shear sensing element ensures accuracy. Housing and connector are 316L stainless steel. Size is 17.5 mm x 45.7 mm. Weight is 58 g (2.0 oz). Mounting thread is 3/8-24 female. Mounting torque is 2.7 to 6.8 N•m. Temperature range is -40 °C to +105 °C. Axial shock limit is 49,050 m/s2 pk. Sealing is hermetic at 5x10-8 atm•cc/s. Relative humidity tolerance is 100% condensing. Cure time is 24 hours.

Applications and Use Cases

This accelerometer excels in low frequency monitoring of fin-fan coolers and slow rotating shafts. It is used with ProTIM Option Low Frequency Acceleration-to-Velocity channel type (-05). The multiple approvals (CSA, ATEX, IECEx) allow deployment in hazardous areas. Its compact size fits tight spaces on rotating equipment.

Installation and Setup

Mount the 200155-18-05 using the 3/8-24 female thread. Apply a mounting torque of 2.7 to 6.8 N•m. The mounting stud option 18 provides a 3/8-24 to M8x1 1-3/8 inch hex plate stud. Ensure the base is clean and flat for optimal coupling. After installation, allow a 24-hour cure time before full operation. Connect excitation voltage between 4.7 and 5.5 Vdc. Verify output bias voltage is +2.5 ± 0.23 Vdc.

Maintenance and Reliability

Regularly inspect the cable and connector for damage. Check mounting torque periodically. The hermetic seal protects against moisture ingress. Operate within the -40 °C to +105 °C range for best reliability. Avoid exceeding the 49,050 m/s2 shock limit. Follow manufacturer guidelines for periodic verification.

Compatibility and Integration

The 200155-18-05 works with Bently Nevada monitoring systems. It is designed for use with ProTIM Option Low Frequency Acceleration-to-Velocity channel type (-05). The multiple approvals (CSA, ATEX, IECEx) ensure global compatibility. Consult the official datasheet for detailed integration steps.
