BENTLY 136703-01
Product Introduction
The Bently Nevada 136703-01 is a rugged industrial accelerometer designed for permanent machinery condition monitoring in harsh environments. Part of Bently Nevada’s comprehensive vibration monitoring portfolio, this high-performance sensor captures casing vibration data essential for predictive maintenance of turbines, compressors, pumps, and other critical rotating equipment.
Featuring a hermetically sealed 316 stainless steel housing, the 136703-01 withstands extreme conditions including moisture, chemicals, and explosive atmospheres. Its broad frequency response (1 Hz to 10 kHz) enables detection of both low-frequency machinery dynamics and high-frequency bearing/gear defects, providing comprehensive machinery health assessment.
Core Advantages and Technical Highlights
Precision Vibration Measurement:
±50 g dynamic range covers most industrial vibration scenarios
100 mV/g sensitivity with ±5% tolerance ensures measurement consistency
1 Hz to 10 kHz frequency response captures both slow-speed and high-frequency defects
