Product Description
Product Overview
- Manufacturer: Bently Nevada
- Series: 3500/25
- Model/Part Number: 3500/25-01-03-00
- Type: Keyphasor Card I/O Module
- Function: The module provides Keyphasor signals to monitor modules in a 3500 rack by converting input signals from proximity probes or magnetic pickups into digital Keyphasor signals. These signals mark the alignment of the Keyphasor transducer with the shaft's Keyphasor mark.
