Bently Nevada 200155-13-05 Low Frequency Trendmaster Pro Accelerometer

Product Introduction

When monitoring slow rotating shafts in fin-fan applications, the Bently Nevada 200155-13-05 Low Frequency Trendmaster Pro accelerometer provides reliable vibration data. This sensor is part of the Trendmaster Pro family, designed for low-frequency acceleration-to-velocity measurements. It is manufactured in the U.S.A. and comes with multiple approvals including CSA, ATEX, and IECEx, making it suitable for hazardous environments.

Technical Specifications

The 200155-13-05 offers a sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz, with a measurement range of ±196 m/s² (±20 g). Its frequency range spans 1.5 to 10,000 Hz (90 to 600,000 cpm), referenced to 80 Hz. The mounted resonant frequency exceeds 20 kHz (>1200 kcpm). Amplitude linearity is within ±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 <800 µA and output bias voltage +2.5 ± 0.23 Vdc. Environmental ratings include an axial shock limit of 49,050 m/s² pk (5,000 g pk), temperature range -40 ºC to +105 ºC (-40 ºF to +221 ºF), hermetic sealing at 5x10⁻⁸ atm•cc/s maximum, and 100% relative humidity condensing non-submerged. Physical size is 17.5 mm x 45.7 mm (11/16 in x 1.8 in), weight 58 g (2.0 oz) typical, with a 3/8-24 female mounting thread and mounting torque 2.7 to 6.8 N•m (2 to 5 ft•lbf). The sensing element is ceramic with shear geometry, and the housing is 316L stainless steel.

Industry Applications

This accelerometer is ideal for fin-fan cooling towers and slow rotating shafts where low-frequency vibration monitoring is critical. The 200155-13-05 excels in applications requiring trend data over extended periods, such as in oil and gas, petrochemical, and power generation facilities. Its rugged construction and multiple approvals ensure reliable operation in harsh conditions.

Installation & Setup Guidance

The 200155-13-05 features a 3/8-24 female mounting thread and includes a mounting stud option (13= 3/8-24 to 5/16-18 UNC, 3/4 inch hex stud). Apply mounting torque between 2.7 to 6.8 N•m (2 to 5 ft•lbf). Ensure the mounting surface is clean and flat for optimal coupling. The sensor is used with the ProTIM Option Low Frequency Acceleration-to-Velocity channel type (-05). Allow 24 hours cure time after installation if adhesive mounting is used.

Maintenance & Reliability

The 200155-13-05 is hermetically sealed to 5x10⁻⁸ atm•cc/s maximum, protecting against moisture and contaminants. Its 316L stainless steel housing resists corrosion. Periodic inspection of the mounting integrity and cable connections is recommended. The ceramic shear sensing element provides long-term stability.
