Bently Nevada 200155-10-05 Low Frequency Trendmaster Pro Accelerometer

Why Choose the Bently Nevada 200155-10-05 for Low Frequency Monitoring?

When slow rotating shafts and fin-fan applications demand precise vibration data, the Bently Nevada 200155-10-05 delivers reliable performance. This Low Frequency Trendmaster Pro Accelerometer is engineered for environments where standard sensors fall short. With multiple approvals including CSA, ATEX, and IECEx, it meets rigorous safety standards for hazardous locations.

Product Overview

The Bently Nevada 200155-10-05 is a low frequency accelerometer designed for use with the ProTIM option Low Frequency Acceleration-to-Velocity channel type (-05). It is ideal for monitoring slow rotating shafts and fin-fan applications. Manufactured in the U.S.A., this sensor features a ceramic shear sensing element and a 316L stainless steel housing and connector material for durability in harsh conditions.

Technical Specifications

The Bently Nevada 200155-10-05 offers a sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz (±12%). Its measurement range is ±196 m/s² (±20 g) and 24.5 mm/s² (2.5 mg). The frequency range referenced to 80 Hz is 1.5 to 10,000 Hz (90 to 600,000 cpm) with a mounted resonant frequency greater than 20 kHz (>1200 kcpm). Amplitude linearity is ±2% (1 to 10 g pk) and transverse sensitivity is ≤7%. Settling time is ≤2000 ms. Excitation voltage is 4.7 to 5.5 Vdc with quiescent current less than 800 µA. Output bias voltage is +2.5 ± 0.23 Vdc. Axial shock limit is 49,050 m/s² pk (5,000 g pk). Temperature range is -40 °C to +105 °C (-40 °F to +221 °F) with hermetic sealing of 5×10⁻⁸ atm·cc/s maximum. Weight is 58 g (2.0 oz) typical. Mounting thread is 3/8-24 female with mounting torque of 2.7 to 6.8 N·m (2 to 5 ft·lbf).

Industry Applications

The 200155-10-05 excels in monitoring slow rotating shafts in machinery such as cooling tower fans, fin-fan heat exchangers, and other low-speed rotating equipment. Its low frequency response down to 1.5 Hz makes it suitable for detecting early bearing wear and imbalance in large, slow-moving assets. In fin-fan applications, the accelerometer provides reliable data for predictive maintenance programs, helping to reduce unplanned downtime.

Installation & Setup Guidance

Mount the Bently Nevada 200155-10-05 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 is 10 3/8-24 to 1 NPT, 1-3/8 inch hex stud. Ensure the mounting surface is clean and flat for optimal coupling. Allow 24 hours cure time for any adhesive used. Connect the accelerometer to a compatible ProTIM module for signal processing.

Maintenance & Reliability

The 200155-10-05 is built with a 316L stainless steel housing and ceramic shear sensing element for long-term reliability. Its hermetic sealing protects against moisture and contaminants. Regular inspection of the mounting integrity and cable connections is recommended. The sensor operates in temperatures from -40 °C to +105 °C and withstands 100% condensing humidity. For extended life, avoid exceeding the axial shock limit of 49,050 m/s² pk.
