Our 3500/50M Tachometer Module features 2 channels which accept input from Proximitor probes or magnetic pickups to measure shaft rotating speed, rotor acceleration, or reverse rotation. The 3500/50M Tachometer conditions the inputs and compares the conditioned signals with user-programmable set points that can drive alarms and relay logic in the 3500 relay modules. Alarm options offered with 3500 Rack Configuration software include Speed Band, Zero Speed, Rotor Acceleration and Reverse Rotation. The Keyphasor and speed measurements are also an integral part of the Bently Nevada Turbine Supervisory Instrumentation (TSI) suite of sensors for steam turbines. The 3500 System is available as a SIL 2 rated system and with multiple Hazardous Area and country-specific approvals available. External terminations and internal barrier versions are also available. You should note that the 3500/50M is not designed for Overspeed Detection.
The four-channel 3500/64 Dynamic Pressure Monitor accepts input from gas turbine dynamic pressure (combustion) transducers and uses this input to drive alarms. The monitor produces band-passed dynamic pressure measured variables. Programmable corner frequencies for the bandpass filter and an additional notch filter can be adjusted as needed. A typical application identifies and tracks gas turbine combustor instabilities. Dynamic Pressure sensors use Bently Nevada charge amplifiers 350500 or 86517 and can integrate a multitude of common dynamic pressure sensors, including the CP series sensors. Additionally, the 3500/64 is available with multiple Hazardous Area and country-specific approvals to tackle any environment.

The 3500/15 AC and DC Power Supplies are half-height modules and must be installed in designated slots on the left side of the rack. The 3500 rack can contain one or two power supplies with any combinations of AC and DC. Either supply can power a full rack.
The 3500/22M, also known as the Transient Data Interface Module (or TDI), is the heart of the 3500 rack system. It allows for configuration of the 3500 rack parameters and serve as the gateway to the System 1 Machinery Condition Monitoring software platform.
The TDI is equipped with a USB port on the front for easy access for configuration, and a 10/100 Ethernet connection on the rear I/O module for communicating with System 1. A rack reset button on the front allows alarm reset with a physical key to lock out configuration changes.
135813-01 is a Display Interface I/O Module developed by Bently Nevada. The System Display is intended to meet the criteria of API Standard 670 and to give a local or remote visual indication of all 3500 Machinery protection System information housed in the rack, such as System Event Lists, Alarm Event Lists, and so on.
Using unique hinged support, it displays mounts easily over the front panel of any full-size 3500 racks. This enables access to the user interface buttons and switches as well as the buffered output connectors on the rack without detaching or turning off the display.
To address this vulnerability, Bently Nevada recommends users obtain 3500 Rack Configuration Version 6.6 or higher from Bently Nevada, which now includes a feature to set enhanced password security. For users that have their 3500 System(s) connected to Bently Nevada's System 1 software, enhanced password security is supported for System 1 Version 21.2 and higher. Using enhanced password security on the 3500 system will break communications with any earlier version of System 1 below Version 21.2
The power supplies and rack interface module reside in the left-most part of the rack which is not counted as a slot i.e. remaining 14 for full and 7 for mini rack are used for other module installation.Power Supply Module (3500/15)The 3500/15 power supply is half heightened module installed on the leftmost side of the rack and installed one above the other creating a redundant system.The respective parts are listed below and also shown in the above figure.3500/15 AC and DC Power Supplies OK LEDLegacy Low Voltage DC Power Input ModuleLegacy High Voltage DC Power Input ModuleLegacy High Voltage AC Power Input ModuleLegacy Low Voltage AC Power Input ModuleUniversal AC Voltage Power Input ModuleHigh Voltage DC Power Input ModuleLow Voltage DC Power Input ModuleThe power supply can be replaced in the running system also as long as the other power supply in the system is working.
