Product Overview
When unplanned downtime threatens your production targets, the Bently Nevada 200150-09-05 provides the reliable vibration data you need to act fast. This General Purpose Trendmaster 2000 or Trendmaster Pro Accelerometer is built for continuous monitoring in harsh environments. With a sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz and a measurement range of ±245 m/s² (±25 g), it captures critical machinery vibrations accurately.
Key Technical Specifications
The 200150-09-05 delivers consistent performance across demanding conditions. Its frequency range spans 10 to 1000 Hz (600 to 60,000 cpm), referenced to 80 Hz. The mounted resonant frequency exceeds 20 kHz, ensuring reliable data up to high frequencies. Amplitude linearity stays within ±2% from 1 to 10 g peak, and transverse sensitivity is ≤7%. Settling time is ≤300 ms, so the sensor stabilizes quickly after power-up.
Electrical requirements are straightforward: an excitation voltage of 4.7 to 5.5 Vdc and quiescent current under 800 µA. The output bias voltage is +2.5 ± 0.23 Vdc. Polarity is defined as SIG+ positive with respect to SIG- for acceleration from base to connector.
Industry Applications
This accelerometer suits general-purpose vibration monitoring on pumps, fans, compressors, and motors. In a petrochemical plant, for example, you can mount the 200150-09-05 on critical rotating equipment to detect early bearing faults. The rugged design withstands axial shock up to 49,050 m/s² pk (5,000 g pk) and operates from -40 °C to +105 °C (-40 °F to +221 °F). Hermetic sealing (5x10⁻⁸ atm•cc/s maximum) and 100% relative humidity tolerance make it reliable in condensing, non-submerged environments.
Installation & Setup Guidance
Mount the accelerometer using the 3/8-24 female thread. The mounting stud option 09 provides a 3/8-24 to 3/4 NPT adapter with a 1-1/4 inch hex stud. Apply a mounting torque of 2.7 to 6.8 N•m (2 to 5 ft•lbf) to ensure proper coupling. Allow 24 hours cure time after installation for the best performance. Connect to a ProTIM option standard acceleration-to-velocity channel type (-01) for integrated signal conditioning.
Maintenance & Reliability
Periodically inspect the accelerometer and its cable for physical damage. The 316L stainless steel housing and connector resist corrosion. The ceramic shear sensing element provides long-term stability. Regular verification of output bias voltage helps confirm sensor health. Follow manufacturer guidelines for any maintenance procedures.
Compatibility & Integration
The 200150-09-05 works with Bently Nevada Trendmaster 2000 and Trendmaster Pro systems. It is designed for general-purpose applications and interfaces with compatible monitoring hardware. Multiple approvals (CSA, ATEX, and IECEx) allow installation in classified areas.
Selection Guide & Purchasing Advice
Before ordering, verify your mounting thread requirements. The 200150-09-05 includes the 3/8-24 to 3/4 NPT stud option. Confirm the measurement range and frequency response match your machinery's vibration characteristics. SpareTechPLC stocks this accelerometer and can advise on availability and lifecycle status.
