Product Overview
When unplanned downtime strikes rotating machinery, the Bently Nevada 200150-16-05 General Purpose Trendmaster 2000 or Trendmaster Pro Accelerometer provides reliable vibration data for early fault detection. This accelerometer helps maintenance engineers monitor bearing wear, imbalance, and misalignment before failures escalate.
Technical Specifications Breakdown
Sensitivity and Measurement Range
The 200150-16-05 delivers a sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz, with ±12% tolerance. Its measurement range spans ±245 m/s² (±25 g) for acceleration, and 14.7 mm/s² (1.5 mg) for low-level vibration. This dual-range capability suits both high-impact and subtle vibration monitoring.
Frequency Response and Resonant Performance
Referenced to 80 Hz, the frequency range covers 10 to 1000 Hz (600 to 60,000 cpm) within ±10%. The mounted resonant frequency exceeds 20 kHz (>1200 kcpm), ensuring accurate readings across typical machine speeds without structural interference.
Environmental Durability
With a temperature range of -40°C to +105°C (-40°F to +221°F) and 100% condensing humidity tolerance, this accelerometer withstands harsh industrial environments. Hermetic sealing at 5x10⁻⁸ atm•cc/s maximum prevents moisture ingress. Axial shock limit of 49,050 m/s² pk (5,000 g pk) protects against sudden impacts.
Industry Applications
Pump and Compressor Monitoring
In chemical plants, the 200150-16-05 mounts directly on pump casings to capture vibration trends. Its 3/8-24 female mounting thread and 2.7 to 6.8 N•m torque range simplify installation on standard studs. The ceramic shear sensing element provides stable output over years of continuous operation.
Fan and Blower Protection
For HVAC or process fans, the accelerometer's 10 to 1000 Hz frequency range covers blade pass frequencies and bearing defects. The +2.5 ± 0.23 Vdc output bias and <800 µA quiescent current ensure compatibility with most data collectors and trend monitoring systems.
Installation and Setup Guidance
Mount the 200150-16-05 using the supplied 3/8-24 to 1/2-13 UNC stud option (code 16) with a 3/4 inch hex. Apply mounting torque between 2.7 and 6.8 N•m (2 to 5 ft•lbf) to ensure proper coupling. Allow 24 hours cure time for adhesive mounts if used. The accelerometer requires 4.7 to 5.5 Vdc excitation voltage. Settling time within 5% of bias is ≤300 ms, enabling quick data acquisition after power-up.
Maintenance and Reliability
From a maintenance engineer's perspective, the 200150-16-05 offers long-term stability with minimal drift. Its 316L stainless steel housing resists corrosion in washdown areas. The hermetic seal eliminates moisture-related failures. Periodic inspection of the mounting stud and cable connections ensures reliable signal transmission. No internal adjustments are needed; simply verify output bias voltage remains within +2.5 ± 0.23 Vdc.
Compatibility and Integration
This accelerometer works seamlessly with Bently Nevada Trendmaster Pro systems and ProTIM option standard acceleration-to-velocity channel type (-01). The SIG+ positive polarity relative to SIG- simplifies wiring to standard data acquisition modules. Multiple approvals (CSA, ATEX, and IECEx) code 05 allow installation in hazardous areas.
Selection Guide and Purchasing Advice
Before ordering, confirm your mounting thread requirement: the 200150-16-05 uses 3/8-24 female thread. The stud option 16 provides a 3/8-24 to 1/2-13 UNC adapter. Verify excitation voltage compatibility with your monitoring system (4.7 to 5.5 Vdc). Contact SpareTechPLC for current availability and lifecycle status of this model.
