Product Overview
When unplanned downtime strikes rotating machinery, the Bently Nevada 200150-07-05 General Purpose Trendmaster 2000 or Trendmaster Pro Accelerometer provides reliable vibration data to prevent failures. This accelerometer offers a cost-effective solution for continuous monitoring, helping you avoid expensive repairs and production losses.
Technical Specifications Breakdown
Understanding key specifications helps you evaluate long-term value. The 200150-07-05 delivers a sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz, ensuring accurate vibration measurement for early fault detection. Its measurement range of ±245 m/s² (±25 g) covers most general machinery applications, reducing the need for multiple sensor types.
The frequency range of 10 to 1000 Hz (600 to 60,000 cpm) targets common rotating speeds, allowing you to monitor bearings and gears effectively. With a mounted resonant frequency above 20 kHz, this accelerometer avoids resonance interference, improving data reliability and reducing false alarms.
Amplitude linearity within ±2% (1 to 10 g pk) ensures consistent performance across operating conditions, minimizing measurement errors that could lead to unnecessary maintenance costs. The low quiescent current of less than 800 µA reduces power consumption in long-term installations.
Industry Applications
In the oil and gas industry, the 200150-07-05 monitors pumps and compressors. Its temperature range of -40 ºC to +105 ºC suits harsh environments, while hermetic sealing (5X10⁻⁸ atm•cc/s maximum) prevents moisture ingress, extending sensor life and reducing replacement frequency.
For manufacturing plants, this accelerometer tracks motor and fan vibrations. The 316L stainless steel housing resists corrosion, lowering total cost of ownership by minimizing downtime for sensor swaps.
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). Ensure the mounting surface is clean and flat to maintain accuracy. Allow a settling time of up to 300 ms after power-up before taking readings. Use the 3/8-24 to 3/8 NPT stud option for adapter connections.
Maintenance & Reliability
Periodically inspect the cable and connector for wear. The 100% relative humidity rating (condensing, non-submerged) allows use in wet environments without special enclosures. With a weight of only 58 g (2.0 oz), the sensor imposes minimal mechanical load on the mounting point, reducing stress-related failures.
Selection Guide & Purchasing Advice
Before purchasing, verify your system's excitation voltage (4.7 to 5.5 Vdc) and output bias voltage requirements. The 200150-07-05 includes multiple approvals (CSA, ATEX, and IECEx) for global use. Contact SpareTechPLC to confirm availability and ensure compatibility with your Trendmaster 2000 or Trendmaster Pro system.
