Bently Nevada 3500/50-01-00 288062-02+133442-01 Tachometer Module

High-Speed Speed Measurement for 3500 Machinery Protection Systems

The Bently Nevada 3500/50-01-00 288062-02+133442-01 functions as a high-performance tachometer module within the 3500 series machinery protection system. This module accepts up to 4 speed sensor inputs for measuring rotational speed and zero-speed detection. Its sturdy housing measures 241 mm in height, 38 mm in width, and 241 mm in depth, fitting standard 3500 rack configurations seamlessly. The total weight reaches approximately 1.1 kg, offering robust durability for continuous monitoring in demanding environments.

This module provides precise speed measurement with 0.1% accuracy across a wide range. The following table details the complete technical specifications for this tachometer solution:

Input Compatibility and Sensor Configuration

The 3500/50-01-00 accepts magnetic pickups and eddy current probes for versatile speed monitoring. Each channel accommodates a wide range of sensor types and mounting configurations. The module handles both active and passive speed sensors without additional conditioning. Engineers can therefore deploy this tachometer across diverse rotating equipment applications.

Measurement Performance and Speed Accuracy

This module delivers speed measurements with ±0.1% accuracy from 0 to 60,000 RPM. The frequency response from 1 Hz to 100 kHz covers low and high-speed machinery. Zero-speed detection provides critical monitoring for startup and shutdown conditions. Users benefit from reliable speed data for control and protection strategies.

System Integration and Alarm Capabilities

The module interfaces with the 3500 rack backplane for seamless system integration. It provides programmable alarms for overspeed and underspeed conditions. The monitor also supports relay outputs for external annunciation. Maintenance teams can therefore implement comprehensive overspeed protection for critical assets.
