Product Details

Manufacturer	Bently Nevada
Series	3500/50
Model/Part Number	3500/50-01-00
Model Type	Tachometer Module

Function

The 3500/50 Tachometer Module is a two-channel module designed to monitor:

Speed: Measures shaft rotative speed.
Acceleration: Tracks rotor acceleration.
Direction: Detects rotor direction.

The module accepts input from proximity probes or magnetic pickups, processes the signals, and compares measurements to user-programmable alarm setpoints. It triggers alarms when thresholds are exceeded, ensuring reliable machinery protection.

Specifications

Inputs

Parameter	Details
Signal Type	Accepts up to two transducer signals from proximity probes or magnetic pickups.
