3500/50 133388-02 | Bently Nevada Tachometer I/O Module

Overview

The 133388-02 Bently Nevada 3500/50 is a dual-channel Tachometer Module designed to measure shaft rotational speed, acceleration, and direction in rotating machinery systems. Compatible with proximity probes and magnetic pickups, it provides reliable signal processing and peak data storage for critical machinery monitoring applications.

Key Features

• Dual-Channel Inputs: Supports two independent channels for simultaneous measurement from multiple sensors.

• Versatile Signal Acquisition: Works with both proximity probes and magnetic pickups for broad compatibility.

• Peak Hold Functionality: Records maximum speed, maximum reverse speed, and total number of reverse rotations.

• Real-Time Data Processing: Continuously calculates rotor speed, acceleration, and rotation direction.

• Alarm Generation: Compares measured values to user-defined thresholds and triggers alarms when limits are exceeded.

• Keyphasor Output: Provides conditioned signals to the 3500 Series backplane for integrated monitoring.
