Bently Nevada 200150-02-05 General Purpose Trendmaster 2000 Accelerometer

Product Overview

This accelerometer is designed for general applications where accurate acceleration-to-velocity conversion is critical. With multiple approvals including CSA, ATEX, and IECEx, it meets global safety standards for hazardous locations.

Technical Specifications Breakdown

The 200150-02-05 offers a sensitivity of 10.2 mV/(m/s2) (100 mV/g) at 80 Hz, ensuring consistent output for vibration analysis. Its measurement range spans ±245 m/s2 (±25 g), suitable for most industrial machinery. The frequency range covers 10 to 1000 Hz (600 to 60,000 cpm), capturing both low-speed and high-speed rotating equipment vibrations. A mounted resonant frequency above 20 kHz (>1200 kcpm) minimizes interference from structural resonances. Amplitude linearity is within ±2% from 1 to 10 g peak, providing accurate readings across the operating range. Transverse sensitivity is ≤7%, reducing cross-axis errors. Settling time is ≤300 ms, allowing quick stabilization after power-up. Excitation voltage is 4.7 to 5.5 Vdc, with quiescent current under 800 µA and output bias voltage of +2.5 ± 0.23 Vdc.

Industry Applications

For example, in a chemical plant, the 200150-02-05 detects early bearing faults in centrifugal pumps, preventing unplanned downtime. Its wide temperature range of -40 ºC to +105 ºC (-40 ºF to +221 ºF) suits outdoor or high-temperature environments. The hermetically sealed design (5X10-8 atm•cc/s maximum leak rate) and 100% relative humidity tolerance ensure reliable performance in condensing conditions.

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 02 uses a 3/8-24 to 3/8-24 UNF 1-3/8 inch hex plate stud. Ensure the mounting surface is clean and flat for optimal coupling. Connect the SIG+ and SIG- leads with correct polarity: SIG+ positive with respect to SIG- for acceleration from base to connector. Allow 24 hours cure time after installation before taking critical measurements.

Maintenance & Reliability

Regularly inspect the accelerometer for physical damage or corrosion, especially in harsh environments. The 316L stainless steel housing and connector resist chemical attack. Check cable integrity and connector tightness periodically. Given the hermetically sealed construction, no internal maintenance is required. Replace the unit if output bias voltage drifts outside +2.5 ± 0.23 Vdc or if sensitivity changes beyond ±12% at 80 Hz.

Selection Guide & Purchasing Advice

Before ordering the Bently Nevada 200150-02-05, verify your application requirements: measurement range, frequency range, and environmental conditions. This model is designed for general purpose use with the ProTIM option standard acceleration-to-velocity channel type (-01). Ensure your monitoring system supports the 10.2 mV/(m/s2) sensitivity and 4.7 to 5.5 Vdc excitation. Contact AutoDCSTech for current availability and lifecycle status.
