Bently Nevada 3500/50 Tachometer Module
The 3500/50M Tachometer Module is a 2-channel module that accepts
input from proximity probes or magnetic pickups to determine shaft
rotative speed, rotor acceleration, or rotor direction. The module
compares these measurements against user-programmable alarm
setpoints and generates alarms when the setpoints are violated.
The Tachometer Module is programmed using the 3500 Rack
Configuration software. The following configuration options are
available:
l Speed Monitoring, Setpoint Alarming and Speed Band Alarming
l Speed Monitoring, Setpoint Alarming and Zero Speed
Notification
l Speed Monitoring, Setpoint Alarming and Rotor Acceleration
Alarming
l Speed Monitoring, Setpoint Alarming and Reverse Rotation
Notification
The 3500 System provides continuous, online
monitoring suitable for machinery protection
applications, and is designed to meet the requirements
of the American Petroleum Institute’s API 670 standard
for such systems. The system’s modular rack-based
design includes the following components:
• 3500/05 Instrument Rack (required)
• One or two 3500/15 Power Supplies (required)
• 3500/22M Transient Data Interface (TDI) Module
(required)
• One or more 3500/XX Monitor Modules
(required)
• One or more 3500/32M (4-channel) or 3500/33
(16-channel) Relay Modules (optional)
• One or two 3500/25 Keyphasor* Modules
(optional)
• One or more 3500/92 Communication Gateway
Modules (optional)
• Input/Output (I/O) Modules (required)
• 3500/94M VGA Display (optional)
• Internal or external intrinsic safety barriers, or
galvanic isolators for hazardous area
installations (optional)
• 3500 System Configuration Software (required)
