Product Description

Overview

The Bently Nevada 169337 is a versatile module available as a high‑performance accelerometer or an external power supply unit. Moreover, it is designed for industrial machinery monitoring, providing reliable vibration data and stable power to Bently Nevada 3500 series racks. The robust construction ensures accurate measurements and long-term operational reliability under harsh industrial conditions. As an accelerometer, the 169337 delivers precise vibration measurements with wide frequency response and integral signal conditioning. In addition, the external power supply variant provides consistent DC power, maintaining reliable operation for the 3500 monitoring system. Both versions are engineered for turbines, compressors, motors, and pumps, enabling effective predictive maintenance programs.
