Product Overview

The Bently Nevada 3500/50 is a two-channel tachometer module designed for accurate measurement of shaft rotational speed, rotor acceleration, and rotor direction. Manufactured by Bently Nevada, a trusted name in machinery protection, this module accepts inputs from proximity probes or magnetic pickups to provide precise data for machinery monitoring systems.

The 3500/50 compares measurements against user-programmable alarm setpoints and activates alarms when thresholds are exceeded, enabling early detection of potential issues. Additionally, it features a peak hold function, which stores the maximum speed values for later analysis, providing valuable insights into system performance and wear.

This module is essential for applications requiring accurate rotational speed and vibration measurements in critical machinery.

Key Features

• Dual Channels: Measures two separate inputs, making it suitable for applications with multiple monitoring points.

• High Accuracy: Provides ± 0.1 rpm accuracy for speeds under 100 rpm.

• Peak Hold Function: Stores maximum speed values for future reference and analysis.

• User-Programmable Alarms: Triggers alarms when measurements exceed preset limits, helping to protect machinery.

• Versatile Inputs: Accepts inputs from both proximity probes and magnetic pickups.

• Efficient Design: Compact size and low power consumption make it suitable for various industrial environments.
