Product Overview
When monitoring slow rotating shafts in fin-fan applications, the Bently Nevada 200155-15-05 Low Frequency Trendmaster Pro accelerometer delivers reliable vibration data. This sensor, part of the Trendmaster Pro series, provides accurate measurements for machinery health assessments.
Technical Specifications
The 200155-15-05 operates with a sensitivity of 10.2 mV/(m/s²) (100 mV/g) at 80 Hz, ensuring precise readings. Its measurement range spans ±196 m/s² (±20 g), covering typical vibration levels in industrial equipment. The frequency range extends from 1.5 to 10,000 Hz (90 to 600,000 cpm), suitable for low-speed machinery. This accelerometer requires an excitation voltage of 4.7 to 5.5 Vdc and draws a quiescent current of less than 800 µA. The output bias voltage is +2.5 ± 0.23 Vdc, with a settling time of ≤2000 ms. It features a mounted resonant frequency above 20 kHz and amplitude linearity of ±2% (1 to 10 g pk). Transverse sensitivity is ≤7%. The sensor uses a ceramic shear sensing element housed in 316L stainless steel. Physical dimensions are 17.5 mm x 45.7 mm (11/16 in x 1.8 in), with a weight of 58 g (2.0 oz). Mounting thread is 3/8-24 female, with a torque range of 2.7 to 6.8 N·m (2 to 5 ft·lbf).
Industry Applications
Engineers select the 200155-15-05 for fin-fan and slow rotating shaft monitoring. Its low-frequency response ensures accurate detection of developing faults in fans, pumps, and compressors. The accelerometer's multiple approvals (CSA, ATEX, and IECEx) allow deployment in hazardous environments. For example, in petrochemical plants, this sensor helps prevent unplanned downtime by providing early warnings of bearing wear or imbalance.
Installation & Setup Guidance
Mount the 200155-15-05 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 15 = 3/8-24 to 3/8-16 UNC, 3/4 inch hex stud. Ensure the surface is clean and flat for optimal coupling. Connect the excitation voltage between 4.7 and 5.5 Vdc, observing polarity: SIG+ positive with respect to SIG-. Allow a cure time of 24 hours after installation for the adhesive to set.
Maintenance & Reliability
Routine inspection of the cable and connector ensures long-term reliability. The accelerometer operates in temperatures from -40 ºC to +105 ºC (-40 ºF to +221 ºF) and withstands axial shock up to 49,050 m/s² pk (5,000 g pk). Its hermetic sealing (5X10⁻⁸ atm·cc/s maximum) protects against moisture. Verify the output bias voltage periodically to detect drift. With proper care, this sensor provides consistent performance for years.
Compatibility & Integration
This accelerometer works with ProTIM Option Low Frequency Acceleration-to-Velocity channel type (-05). It integrates into existing Bently Nevada monitoring systems for seamless data collection. The multiple approvals (CSA, ATEX, and IECEx) simplify compliance in global installations.
Selection Guide & Purchasing Advice
Before ordering, confirm the mounting thread (3/8-24 female) and stud option (15) match your application. Verify the excitation voltage range (4.7 to 5.5 Vdc) and ensure compatibility with your monitoring system. SpareTechPLC offers the Bently Nevada 200155-15-05 with fast shipping and expert support.
