Description
The Bently Nevada™ 3500/45 Position Monitor is a 4-channel instrument that accepts input from proximity transducers, Rotary Position Transducers (RPTs), DC Linear Variable Differential Transformers (DC LVDTs), AC Linear Variable Differential Transformers (AC LVDTs), and rotary potentiometers. The monitor conditions the input and compares the conditioned signals with user-programmable alarms.
You can program each channel using the 3500 Rack Configuration Software to perform the following functions:
Axial (thrust) Position
Differential Expansion
Standard Single Ramp Differential Expansion
Non-standard Single Ramp Differential Expansion
Dual Ramp Differential Expansion
Complementary Differentia
Expansion
Case Expansion
Valve Position
The monitor channels are programmed in pairs and can perform up to two of these functions at a time. For example, Channels 1 and 2 can perform one function while Channels 3 and 4 may perform the same or a different function.
The primary purpose of the 3500/45 Position Monitor is to provide the following:
Machinery protection by continuously comparing monitored parameters against configured alarm setpoints to drive alarms
Essential machine information for operations and maintenance personnel
Each channel, depending on configuration, typically conditions its input signal to generate various parameters called measured variables. You can establish alert setpoints for each active measured variable and danger setpoints for any two of the active measured variables.
Firmware and Software Requirements
When adding the 3500/45 Position Monitor to an existing 3500 system, the following firmware and software versions or later are required:
3500/20 RIM Firmware rev. G
