Q1: What is the primary function of the 3500/22-01-01-01?
It is a Transient Data Interface (TDI) Module that serves as the communication bridge between the 3500 Machinery Protection System rack and Bently Nevada’s System 1 condition monitoring software. It continuously collects steady-state and transient dynamic data from monitoring modules and transmits it via Ethernet for analysis and diagnostics .
Q2: Is the TDI part of the machinery protection path?
No. The TDI provides certain functions common to the entire rack, but it is not part of the critical monitoring path and has no effect on the proper, normal operation of the overall monitor system for automatic machinery protection . It is designed for condition monitoring and data collection purposes only.
Q3: What data types does the TDI collect?
The TDI collects:
Static/Steady-State Data: Continuous measurements from monitoring modules
Transient Dynamic Data: Waveform snapshots captured during startup, coast-down, or alarm events
Alarm Data: Pre-alarm and post-alarm waveform data with programmable intervals
Q4: What communication interfaces does this module support?
The TDI provides:
Ethernet (10Base-T/100Base-TX): For System 1 and configuration software communication
RS-232 Serial: Up to 115.2 kbaud for local configuration
USB: Front-panel connection for local diagnostics
Q5: Is the TDI hot-swappable?
In redundant TDI configurations, yes. For single TDI racks, replacement requires a brief shutdown. The TDI resides in Slot 1 (adjacent to power supplies) of the 3500 rack.
The Bently Nevada 330105-02-12-05-02-00 is an 8 mm reverse-mount proximity probe from the 3300 XL series, engineered for non-contact vibration and position monitoring in space-constrained machinery.
The Bently Nevada 330130-085-00-00 is an 8.5-meter standard extension cable for the 3300 XL 8 mm Proximity Transducer System. It connects a 3300 XL proximity probe to its Proximitor® sensor, transmitting eddy-current displacement signals for vibration, axial position, and Keyphasor measurements on critical rotating machinery.
The Bently Nevada 21000-00-00-15-030-04-00 is a Proximity Probe Housing Assembly from the 21000 series, designed to provide a secure, environmentally sealed mounting interface for reverse-mount proximity probes on critical rotating machinery.
The Bently Nevada 330780-50-00 is a 5.0-meter Proximitor® Sensor for the 3300 XL 11 mm Proximity Transducer System. It receives signals from a 3300 XL 11 mm probe and its extension cable, conditioning them into a linear voltage output proportional to shaft displacement for radial vibration, axial thrust position, and Keyphasor measurement.
The Bently Nevada 21747-040-00 is a 4-meter Proximitor probe extension cable designed for the 3300 and 7200 Series Proximity Transducer Systems.
