Product Overview
When selecting a reliable vibration sensor for general machinery monitoring, the Bently Nevada 200150-06-05 General Purpose Trendmaster 2000 or Trendmaster Pro Accelerometer delivers consistent performance. This accelerometer is designed for use with the ProTIM option standard acceleration-to-velocity channel type (-01) in general applications. It comes with mounting stud option 06 (3/8-24 to 1/4 NPT, 3/4 inch hex stud) and approvals 05 (CSA, ATEX, and IECEx).
Technical Specifications Breakdown
Understanding key specifications helps you evaluate if this accelerometer meets your monitoring needs. The sensitivity at 80 Hz is 10.2 mV/(m/s²) (100 mV/g) with a ±12% tolerance, providing a clear signal for vibration analysis. The measurement range is ±245 m/s² (±25 g), suitable for typical industrial machinery. The frequency range is 10 to 1000 Hz (600 to 60,000 cpm) referenced to 80 Hz with ±10% tolerance. The mounted resonant frequency exceeds 20 kHz (>1200 kcpm), ensuring accurate readings across the operating band. Amplitude linearity is ±2% (1 to 10 g pk), and transverse sensitivity is ≤7%. Settling time within 5% of bias is ≤300 ms. Excitation voltage ranges from 4.7 to 5.5 Vdc, with quiescent current under 800 µA and output bias voltage of +2.5 ± 0.23 Vdc. The accelerometer also offers a measurement range of 14.7 mm/s² (1.5 mg).
Industry Applications
The 200150-06-05 is ideal for monitoring rotating equipment such as pumps, fans, compressors, and motors in general industrial environments. Its robust design with a ceramic shear sensing element and 316L stainless steel housing ensures durability in harsh conditions. The multiple approvals (CSA, ATEX, and IECEx) allow deployment in hazardous areas where safety certifications are required.
Installation & Setup Guidance
Proper mounting is critical for accurate vibration data. Use the 3/8-24 female mounting thread and apply a mounting torque of 2.7 to 6.8 N•m (2 to 5 ft•lbf). The accelerometer has a polarity where SIG+ is positive with respect to SIG- when acceleration is from base to connector. Allow 24 hours cure time after installation before taking critical measurements. Ensure the excitation voltage is between 4.7 and 5.5 Vdc.
Maintenance & Reliability
The hermetic sealing (5x10⁻⁸ atm•cc/s maximum) protects against moisture and contaminants, supporting 100% relative humidity (condensing, non-submerged). The temperature range is -40 °C to +105 °C (-40 °F to +221 °F), with a storage range of -55 °C to +121 °C (-67 °F to +250 °F). The axial shock limit is 49,050 m/s² pk (5,000 g pk). Regular inspection of the mounting and cable connections helps maintain reliable operation. The accelerometer weighs 58 g (2.0 oz) typical and has a size of 17.5 mm x 45.7 mm (11/16 in x 1.8 in).
