Product Overview
When slow rotating shafts and fin-fan applications demand precise vibration monitoring, the Bently Nevada 200155-13-05 Low Frequency Trendmaster Pro accelerometer delivers reliable performance. This accelerometer is engineered for low-frequency measurements, making it ideal for machinery that operates at slower speeds. With multiple approvals (CSA, ATEX, and IECEx), it meets stringent safety standards for hazardous environments.
Technical Specifications Breakdown
The 200155-13-05 offers a sensitivity of 10.2 mV/(m/s²) at 80 Hz, providing accurate signal conversion for vibration analysis. Its measurement range spans ±196 m/s², covering a wide amplitude of vibration levels. The frequency range extends from 1.5 Hz to 10,000 Hz, ensuring low-frequency detection capabilities. The mounted resonant frequency exceeds 20 kHz, minimizing interference from structural resonances. Amplitude linearity remains within ±2% from 1 to 10 g peak, ensuring consistent performance across the measurement range.
Industry Applications
This accelerometer excels in monitoring slow rotating shafts in fans, pumps, and compressors. In fin-fan applications, where air movement is critical, the 200155-13-05 detects early signs of bearing wear or imbalance. Its low-frequency response captures subtle vibrations that higher-frequency sensors might miss, preventing unexpected downtime.
Installation & Setup Guidance
Mount the accelerometer using the 3/8-24 female thread with a mounting torque of 2.7 to 6.8 N•m. The mounting stud option (13) uses a 3/8-24 to 5/16-18 UNC, 3/4 inch hex stud. Ensure the surface is clean and flat for optimal coupling. The excitation voltage ranges from 4.7 to 5.5 Vdc, and the quiescent current is less than 800 µA. Allow up to 2000 ms settling time after power-up for accurate readings.
Maintenance & Reliability
The hermetically sealed design (5x10⁻⁸ atm•cc/s maximum leakage) protects against moisture and contaminants. The 316L stainless steel housing and connector resist corrosion in harsh environments. The ceramic shear sensing element provides long-term stability. Operating temperature ranges from -40°C to +105°C, with storage capability from -55°C to +121°C. Regular inspection of mounting integrity and cable condition ensures reliable performance.
Buying Guide
When purchasing the 200155-13-05, verify the mounting thread compatibility with your equipment. The accelerometer weighs 58 g and measures 17.5 mm x 45.7 mm. SpareTechPLC offers this model with multiple approvals, ensuring compliance with global standards. Contact SpareTechPLC for current lifecycle status and availability before ordering.
