3500/50 133434-01 Bently Nevada Tachometer I/O with External Terminations

Overview

The 133434-01 Bently Nevada 3500/50 is a dual-channel Tachometer I/O Module with external terminations, engineered for precise measurement of shaft rotational speed, rotor acceleration, and rotor direction. The module interfaces with proximity probes or magnetic pickups and includes programmable alarms to trigger when measured parameters exceed user-defined limits.

Key Features

• Dual-Channel Input: Accommodates two independent proximity or magnetic transducer signals.

• External Terminations: Simplifies wiring and allows flexible installation in existing 3500 Series racks.

• Advanced Signal Processing: Continuously calculates shaft speed, rotor acceleration, and rotation direction.

• Alarm Functionality: Compares measurements against setpoints to provide real-time alerting for anomalies.

• Peak Hold & Monitoring: Records critical operational data for analysis and maintenance purposes.

• Rack Integration: Fits in one full-height rear slot in the 3500 Series rack system.
