Product Overview
The Bently Nevada 200155-13-05 is a low frequency Trendmaster Pro accelerometer engineered for continuous vibration monitoring on slow-rotating machinery such as fin-fan coolers and low-speed shafts. This industrial automation module delivers precise acceleration measurements across a wide frequency span, making it a reliable choice for predictive maintenance programs.
Built with a ceramic shear sensing element and housed in 316L stainless steel, the Bently Nevada 200155-13-05 withstands harsh environmental conditions. Its multiple approvals (CSA, ATEX, and IECEx) confirm suitability for hazardous-area installations, while the 3/8-24 to 5/16-18 UNC mounting stud option simplifies retrofitting on existing equipment.

Key Features and Benefits
-
Low Frequency Performance: The 200155-13-05 captures vibration down to 1.5 Hz, ideal for slow-speed equipment where early fault detection is critical.
-
High Accuracy: Amplitude linearity of ±2% and transverse sensitivity ≤7% ensure dependable measurement data.
-
Robust Construction: Hermetic sealing and 316L stainless steel housing protect against moisture and corrosive environments.
-
Global Approvals: CSA, ATEX, and IECEx certifications simplify compliance for international installations.
-
Quick Stabilization: Settling time within 5% of bias in ≤2000 ms reduces wait time after power-up.
Industry Applications
The Bently Nevada 200155-13-05 excels in monitoring fin-fan coolers and slow-rotating shafts—equipment prone to imbalance, misalignment, and bearing wear at low speeds. In petrochemical plants, this accelerometer helps detect developing faults before they lead to unplanned downtime.
For example, on a fin-fan cooler operating at 300 RPM, the 200155-13-05's low frequency range (down to 1.5 Hz) captures the fundamental vibration signature, enabling early diagnosis of blade fouling or drive train issues. This proactive approach reduces maintenance costs and extends machinery life.
Installation and Setup
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). Ensure the mounting surface is flat and clean to achieve proper coupling. Connect the excitation voltage (4.7 to 5.5 Vdc) and observe correct polarity: SIG+ positive with respect to SIG-.
After installation, allow the sensor to settle for up to 2000 ms before taking measurements. For best results, use the ProTIM option with Low Frequency Acceleration-to-Velocity channel type (-05) as specified.
Maintenance and Reliability
Routine inspection of the accelerometer and its cable connections helps maintain measurement integrity. Check for physical damage, loose mounting, or contamination that could affect performance. The hermetically sealed design minimizes moisture ingress, but periodic verification of output bias voltage is recommended.
Operating within the specified temperature range (-40 ºC to +105 ºC) and avoiding shock beyond 49,050 m/s² will ensure long-term reliability. Regular calibration checks, as per site standards, help sustain accuracy.
Selection Guide
When selecting a replacement accelerometer, verify the mounting thread size (3/8-24 female) and the stud option (13 = 3/8-24 to 5/16-18 UNC, 3/4 inch hex stud). Confirm the required approvals (05 = CSA, ATEX, IECEx) for your area classification. Also ensure compatibility with your monitoring system's excitation voltage and input range.
