Product Overview
The Bently Nevada 200150-04-05 is a General Purpose Trendmaster 2000 or Trendmaster Pro Accelerometer designed for reliable vibration measurement in industrial environments. Manufactured in the U.S.A., this accelerometer offers robust performance with multiple approvals including CSA, ATEX, and IECEx, making it suitable for hazardous area applications. Its compact size and stainless steel construction ensure durability in demanding conditions.
Technical Specifications Breakdown
Sensitivity and Measurement Range
At 80 Hz, the 200150-04-05 delivers a sensitivity of 10.2 mV/(m/s2) (100 mV/g) with a tolerance of ±12%. This accelerometer measures acceleration up to ±245 m/s2 (±25 g) and features a frequency range of 10 to 1000 Hz (600 to 60,000 cpm), referenced to 80 Hz. The mounted resonant frequency exceeds 20 kHz, ensuring accurate readings across a wide spectrum.
Electrical Characteristics
Operating with an excitation voltage of 4.7 to 5.5 Vdc, the device consumes a quiescent current of less than 800 µA. The output bias voltage is +2.5 ± 0.23 Vdc, and the settling time is ≤300 ms (within 5% of bias). Polarity is positive when acceleration is applied from base to connector.
Environmental Durability
With a temperature range of -40 ºC to +105 ºC (-40 ºF to +221 ºF), the accelerometer withstands extreme conditions. It features hermetic sealing with a maximum leak rate of 5X10-8 atm•cc/s, and operates in 100% relative humidity (condensing, non-submerged). Axial shock limit is 49,050 m/s2 pk (5,000 g pk).
Physical Dimensions
Measuring 17.5 mm x 45.7 mm (11/16 in x 1.8 in) and weighing 58 g (2.0 oz) typical, the unit has a 3/8-24 female mounting thread and requires a mounting torque of 2.7 to 6.8 N•m (2 to 5 ft•lbf). The housing and connector are made of 316L stainless steel, with a ceramic shear sensing element.
Industry Applications
This accelerometer is ideal for general vibration monitoring in rotating machinery such as pumps, fans, compressors, and motors. Its multiple approvals allow use in potentially explosive atmospheres, making it a versatile choice for oil and gas, chemical, and power generation industries. The wide frequency range supports both low-speed and high-speed machinery analysis.
Installation & Setup Guidance
Mount the accelerometer using the 3/8-24 female thread with a torque between 2.7 and 6.8 N•m. Ensure the mounting surface is clean and flat for optimal signal transfer. The unit is designed for use with ProTIM Option Standard Acceleration-to-Velocity channel type (-01). Allow 24 hours cure time after installation if adhesive mounting is used. For best results, avoid mounting on painted or coated surfaces.
Maintenance & Reliability
The hermetically sealed 316L stainless steel construction provides excellent corrosion resistance and long-term reliability. No routine maintenance is required, but periodic inspection of the mounting integrity and cable connections is recommended. The ceramic shear sensing element ensures stable performance over time. Verify proper operation by checking output bias voltage periodically.
Selection Guide & Purchasing Advice
When selecting the 200150-04-05, verify the mounting stud option: code 04 corresponds to a 3/8-24 to 1/4 NPT 1-3/8 inch hex plate stud. The approval code 05 includes CSA, ATEX, and IECEx certifications. Ensure your monitoring system is compatible with the 10.2 mV/(m/s2) sensitivity and 4.7 to 5.5 Vdc excitation.
