Overview
Built with 316 stainless steel construction and hermetic welding, this accelerometer ensures long-lasting reliability even in the harshest plant environments. Moreover, the integral PTFE-insulated cable maintains excellent electrical stability while resisting oil, moisture, and chemical contamination. As a result, users can count on consistent and accurate data under demanding operating conditions.
In addition, the 330425-02-05 integrates smoothly with Bently Nevada 3500, 3701/46E, and Trendmaster Pro systems, allowing efficient data transfer and simplified installation across existing monitoring setups. Furthermore, its low noise output and wide frequency response make it ideal for continuous monitoring of turbines, compressors, pumps, and large electric motors.
