Bently Nevada 3500/50M 286566-02 Tachometer Module

Description

The Bently Nevada 3500/50M 286566-02 Tachometer Module is engineered for monitoring industrial machinery. It tracks shaft speed, rotor acceleration, and rotor direction using proximity probes or magnetic pickups. Alarms are triggered when measurements deviate from user-defined setpoints.

Product Features

• Monitoring Capabilities: Measures shaft speed, rotor acceleration, and rotor direction.
• Alarm Triggers: Compares measurements to user-programmable setpoints.
• Configuration Options: Speed monitoring, setpoint alarming, and speed band alarming.
• Programming: Configurable through 3500 Rack Configuration Software.
