Introduction
Industrial machinery has evolved from reactive repairs to predictive maintenance. The Bently Nevada 200150-08-05 General Purpose Trendmaster 2000 or Trendmaster Pro Accelerometer represents this shift, offering precise vibration monitoring to detect early signs of wear. As part of the Trendmaster family, this accelerometer helps plant engineers reduce unplanned downtime and extend equipment life.
Technical Specifications Breakdown
The 200150-08-05 delivers a sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz, with a measurement range of ±245 m/s² (±25 g). Its frequency range spans 10 to 1000 Hz (600 to 60,000 cpm), referenced to 80 Hz, making it suitable for general machinery monitoring. The mounted resonant frequency exceeds 20 kHz, ensuring accurate readings across its operating band. Amplitude linearity stays within ±2% from 1 to 10 g peak, and transverse sensitivity is ≤7%, minimizing cross-axis errors. The accelerometer settles within 5% of bias in ≤300 ms, enabling quick response after power-up.
Industry Applications
In rotating equipment such as pumps, fans, and compressors, the 200150-08-05 provides continuous vibration data. Its ceramic shear sensing element and 316L stainless steel housing withstand harsh environments. With a temperature range of -40°C to +105°C and 100% relative humidity tolerance (condensing, non-submerged), it suits outdoor or washdown areas. The multiple approvals (CSA, ATEX, and IECEx) allow deployment in hazardous locations.
Installation & Setup Guidance
Mount the accelerometer using the 3/8-24 female thread with a mounting torque of 2.7 to 6.8 N·m (2 to 5 ft·lbf). The mounting stud option 08 provides a 3/8-24 to 1/2 NPT 1 inch hex stud for versatile attachment. Ensure the mounting surface is clean and flat for optimal coupling. Connect SIG+ and SIG- with proper polarity, as the signal is positive with respect to SIG- when acceleration goes from base to connector. Excitation voltage ranges from 4.7 to 5.5 Vdc, and quiescent current is <800 µA.
Maintenance & Reliability
Routine inspection of the accelerometer and its cable connections helps maintain data integrity. The hermetically sealed design (5x10⁻⁸ atm·cc/s maximum leakage) prevents moisture ingress. After installation, allow a 24-hour cure time for the mounting adhesive if used. The output bias voltage of +2.5 ± 0.23 Vdc provides a baseline for diagnostic checks. Periodic verification of sensitivity and frequency response ensures long-term accuracy.
Compatibility & Integration
The 200150-08-05 works with the ProTIM option Standard Acceleration-to-Velocity channel type (-01) for general application monitoring. It connects to Bently Nevada monitoring systems that accept accelerometer inputs. The multiple approvals (CSA, ATEX, and IECEx) simplify integration into global installations requiring certified equipment.
Selection Guide & Purchasing Advice
Before ordering, verify the mounting thread (3/8-24 female) and stud option (08 = 3/8-24 to 1/2 NPT). Confirm that the excitation voltage (4.7 to 5.5 Vdc) matches your system. The 200150-08-05 is made in the U.S.A. and weighs 58 g (2.0 oz) typical. Contact SpareTechPLC for current availability and lifecycle status.
