200150-08-05 | Bently Nevada 100 mV/g General Purpose Accelerometer

What Is the Bently Nevada 200150-08-05?

When reliable vibration data is essential for machinery health, the 200150-08-05 from Bently Nevada provides a proven solution. This General Purpose Trendmaster 2000 or Trendmaster Pro Accelerometer is designed for continuous monitoring in industrial environments. With a sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz, it accurately captures vibration signals for early fault detection. The unit is manufactured in the U.S.A. and carries multiple approvals including CSA, ATEX, and IECEx.

One distinctive spec is the settling time of ≤300 ms, which ensures the accelerometer stabilizes quickly after power-up for accurate readings from the start.

Real-World Applications

The 200150-08-05 is ideal for general vibration monitoring on rotating machinery such as pumps, fans, and motors. Its robust 316L stainless steel housing withstands harsh conditions, while the hermetically sealed design (5×10⁻⁸ atm·cc/s max) protects against moisture. For example, in a chemical plant where condensing humidity is common, this accelerometer delivers reliable data without performance degradation. Its wide temperature range also suits outdoor installations in extreme climates.

Installation and Mounting Guide

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 included stud option (3/8-24 to 1/2 NPT 1 inch hex) simplifies attachment. Ensure the mounting surface is clean and flat for optimal coupling. After installation, allow a cure time of 24 hours before taking critical measurements to let the system stabilize. Always follow the manufacturer's manual for wiring polarity: SIG+ positive with respect to SIG-.

Maintenance and Reliability

For long-term reliability, inspect the accelerometer periodically for physical damage or corrosion. The ceramic shear sensing element and hermetic sealing minimize drift, reducing the need for frequent recalibration. Regular verification of output bias voltage (2.5 ± 0.23 Vdc) helps confirm proper operation. This low-maintenance design supports cost-effective condition monitoring programs.

Compatibility and Integration

The 200150-08-05 works seamlessly with Bently Nevada Trendmaster 2000 and Trendmaster Pro systems. It uses the Standard Acceleration-to-Velocity channel type (-01) for direct integration. The accelerometer's 4.7 to 5.5 Vdc excitation voltage matches common monitoring module power supplies. For systems requiring multiple approvals, this model's CSA, ATEX, and IECEx certifications simplify global deployment.
