3500/50 Bently Nevada Tachometer Module

Description 
The 3500/50 Tachometer Module is a 2-channel module that accepts input from proximity probes or magnetic pickups (except as noted) to determine shaft rotative speed, rotor acceleration, or rotor direction, compares these measurements against user-programmable alarm setpoints, and generates alarms when these setpoints are violated. The 3500/50 Tachometer Module is programmed using the 3500 Rack Configuration Software and can be configured with four different options: 
1. Speed Monitoring, Setpoint Alarming, and Speed Band Alarming. 
2. Speed Monitoring, Setpoint Alarming, and Zero Speed Notification. 
3. Speed Monitoring, Setpoint Alarming, and Rotor Acceleration Alarming. 
4. Speed Monitoring, Setpoint Alarming, and Reverse Rotation Notification. 
The 3500/50 can be configured to supply conditioned Keyphasor® signals to the backplane of the 3500 rack for use by other monitors, thus eliminating the need for a separate Keyphasor module in the rack. The 3500/50 also has a peak hold feature that stores the highest speed, highest reverse speed, or number of reverse rotations (depending on channel type selected) that the machine has reached. These peak values can be reset by the user.
