Product Overview
When unplanned downtime strikes your rotating machinery, the Bently Nevada 200150-11-05 General Purpose Trendmaster 2000 or Trendmaster Pro Accelerometer delivers precise vibration data to keep operations running. This industrial accelerometer, part of the trusted Trendmaster series, offers a measurement range of ±245 m/s² (±25 g) and sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz. With multiple approvals including CSA, ATEX, and IECEx, it meets stringent safety standards for hazardous environments.
Technical Specifications Breakdown
The 200150-11-05 excels in critical performance areas:
- Frequency Range: 10 to 1000 Hz (600 to 60,000 cpm) referenced to 80 Hz, covering essential vibration monitoring for motors, pumps, and fans.
- Environmental Resilience: Operates from -40 °C to +105 °C (-40 °F to +221 °F) and withstands 100% relative humidity (condensing, non-submerged). This reduces the need for costly climate-controlled enclosures.
- Shock Resistance: Axial shock limit of 49,050 m/s² pk (5,000 g pk) ensures survival in harsh industrial conditions, minimizing replacement costs.
- Output Bias Voltage: +2.5 ± 0.23 Vdc provides a stable baseline for accurate readings, reducing false alarms and maintenance interventions.
Industry Applications
In oil and gas facilities, the 200150-11-05 monitors compressor vibrations in ATEX-rated zones, preventing catastrophic failures. For power generation, its 100% humidity rating suits turbine bearing monitoring in coastal plants. The manufacturing sector benefits from its shear sensing geometry and ceramic element, delivering reliable data for predictive maintenance programs.
Installation & Setup Guidance
Mount the accelerometer using the 3/8-24 female thread with a torque of 2.7 to 6.8 N·m (2 to 5 ft·lbf). The mounting stud option (11 = 3/8-24 to 1-1/4 NPT, 1-3/4 inch hex stud) simplifies retrofit into existing ports. Ensure the base-to-connector polarity (SIG+ positive) is correct. Allow 24 hours cure time after installation for adhesive bonding if used.
Maintenance & Reliability
The hermetically sealed design (5×10⁻⁸ atm·cc/s maximum leak rate) prevents moisture ingress, extending service life. Inspect the 316L stainless steel housing annually for corrosion in aggressive environments. With a mounted resonant frequency above 20 kHz, the sensor maintains accuracy over years of use, reducing total cost of ownership.
Compatibility & Integration
This accelerometer works with the ProTIM option (Standard Acceleration-to-Velocity channel type -01) for seamless data integration. It pairs with Bently Nevada monitoring systems for real-time vibration analysis. The 4.7 to 5.5 Vdc excitation voltage and quiescent current under 800 µA ensure low power consumption, compatible with most industrial I/O modules.
Buying Guide & Purchasing Advice
Before ordering the 200150-11-05, verify your mounting thread (3/8-24 female) and application temperature range (-40 °C to +105 °C). SpareTechPLC stocks this model with fast shipping and expert support. Contact our team to confirm availability and lifecycle status for your project.
