Bently Nevada 3500/93 135785-02 Back-lighted LCD System Display API 670 Compliant with IP65 Rating

The Bently Nevada 3500/93, also known as the 135785-02 Display Unit, is basically the visual layer sitting on top of the Bently Nevada 3500 Monitoring System.

In many plants, people just use it as the 3500/93 Back-lighted Display for quick on-site checking.

• Real-time visual interface: The Bently Nevada 3500/93 Display Unit, together with the 135785-02 Display Unit / back-lighted display, is basically there to give you a direct window at the machine. You’re not pulling data from a separate PC or going back to the control room all the time. On-site, you can just check the 3500/93 and see what’s going on in real time—vibration levels, shaft position, speed, all those key channel values from the Machinery Protection Screen.
• On-site data & alarm visibility: What operators usually like about this setup is the simplicity. System Display Module information and alarm event lists are shown right at the equipment site. So when something changes, you don’t really need extra steps to confirm it. It helps in industrial machinery protection and critical asset monitoring, especially when timing matters and you just want quick visibility.
• Back-lighted readability (135785-02 model): The 135785-02 version comes with a back-lighted LCD screen, and honestly that makes a difference in the field. In low-light rooms or harsh industrial environments, you still get a clear read. It’s not fancy, just practical—works well for harsh environment operation where visibility can’t be compromised.
• API 670 compliant design: This unit is built in line with API 670 compliant requirements, so it fits into standard machinery protection systems used in power plant instrumentation, rotating equipment safety, and similar setups. It’s a pretty common fit in emergency shutdown system (ESD) architectures as well.
• Flexible mounting & long-distance connection: Installation is flexible—Face, Rack, Panel, or Wall mounting options are all supported. Through the Display Interface Module (DIM), it can be placed up to around 1,220 meters (4,000 feet) away from the 3500 rack. That makes it useful when you need remote rack visualization or when equipment isn’t located near the control cabinet.
• Rugged industrial build: Front panel is IP65 rated, so dust and water protection is solid. Operating range is -20°C to +60°C, which makes it suitable for most industrial sites where conditions are not exactly clean or controlled.

• Critical Asset Protection: This one is mainly used when you need either local or remote monitoring of industrial rotating machinery. Things like steam turbines, gas turbines, or those big centrifugal compressors—you basically just keep an eye on their running condition without constantly going into the control system.
• Power Plant Instrumentation: In power generation sites, the Bently Nevada 3500/93 Display Unit often sits there as a quick visual point. Operators just glance at it and get a feel for turbine-generator health, instead of digging through multiple screens in the system.
• Remote Rack Visualization: Sometimes the main 3500 Monitoring System rack isn’t in a very convenient place, or even in a restricted area. In that case, the 135785-02 Display Unit with 3500/93 setup is used to bring the data out—so you can still see everything in the control room or near the operator desk without going back to the rack.
• Emergency Shutdown Systems (ESD): In ESD configurations, it’s not really doing control, more like a secondary confirmation layer. People use it to double-check alarm conditions before any manual action or automatic shutdown kicks in, just to avoid mistakes.
• Oil & Gas Facilities: It’s also widely used in refineries and offshore platforms. Under pretty harsh conditions, it supports monitoring of shaft eccentricity, thrust position, and radial vibration. Basically it keeps an eye on rotating equipment when the environment is not exactly friendly.
