Product Overview
When you need reliable vibration monitoring for general industrial machinery, the Bently Nevada 200150-14-05 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) and suits a wide range of applications. Its compact form factor and rugged construction make it a practical choice for continuous condition monitoring.
Key Technical Specifications
The 200150-14-05 offers a sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz, with a measurement range of ±245 m/s² (±25 g). It operates across a frequency range of 10 to 1000 Hz (600 to 60,000 cpm) referenced to 80 Hz. The mounted resonant frequency exceeds 20 kHz (>1200 kcpm), ensuring accurate readings in demanding environments. Amplitude linearity is within ±2% (1 to 10 g pk), and transverse sensitivity is ≤7%. The accelerometer settles within 5% of bias in ≤300 ms.
Electrical requirements include an excitation voltage of 4.7 to 5.5 Vdc, quiescent current <800 µA, and an output bias voltage of +2.5 ± 0.23 Vdc. Polarity is SIG+ positive with respect to SIG- when acceleration is from base to connector.
Environmental Durability
This accelerometer withstands harsh conditions with a temperature range of -40 ºC to +105 ºC (-40 ºF to +221 ºF). It handles axial shock limits up to 49,050 m/s² pk (5,000 g pk). Hermetic sealing meets 5X10⁻⁸ atm•cc/s (3.1X10⁻⁹ atm•in³/s) maximum, and it operates in 100% relative humidity, condensing, non-submerged.
Physical Design and Mounting
The 200150-14-05 measures 17.5 mm x 45.7 mm (11/16 in x 1.8 in) and weighs 58 g (2.0 oz), typical. It features a 3/8-24 female mounting thread with a mounting stud option of 3/8-24 to 3/8-24 UNF, 3/4 inch hex stud. Recommended mounting torque is 2.7 to 6.8 N•m (2 to 5 ft•lbf). The sensing element is ceramic with a shear geometry, and the housing and connector are made of 316L stainless steel. Cure time is 24 hours, with a storage temperature range of -55 ºC to +121 ºC (-67 ºF to +250 ºF).
Approvals and Compliance
The 200150-14-05 carries multiple approvals: CSA, ATEX, and IECEx (approval code 05). These certifications make it suitable for use in hazardous locations, ensuring safety and reliability in critical applications.
Applications and Integration
This accelerometer is ideal for general vibration monitoring on pumps, fans, motors, compressors, and other rotating machinery. Its high sensitivity and wide frequency range allow detection of both low and high frequency faults. It integrates seamlessly with Bently Nevada monitoring systems using the ProTIM option.
Installation and Setup Guidance
Mount the accelerometer using the provided 3/8-24 female thread. Apply the specified torque of 2.7 to 6.8 N•m to ensure proper coupling. Allow 24 hours cure time after installation for optimal performance. Connect to the monitoring system using appropriate cabling, ensuring polarity matches (SIG+ positive).
Maintenance and Reliability
Periodically inspect the accelerometer for physical damage or contamination. Verify output bias voltage remains within +2.5 ± 0.23 Vdc. The hermetically sealed design prevents moisture ingress, extending service life in humid environments. Follow manufacturer guidelines for routine calibration checks.
Selection Guide and Purchasing Advice
Before purchasing the 200150-14-05, confirm your system requires a General Purpose Trendmaster 2000 or Trendmaster Pro Accelerometer with the specified sensitivity and approvals. Verify mounting thread compatibility and environmental conditions. SpareTechPLC offers this accelerometer with fast shipping and expert support to help you select the right part for your application.
