Core Features
- 4-Channel Monitoring Capability: Equipped with 4 independent channels, the monitor can simultaneously track vibration parameters of multiple measurement points, providing comprehensive coverage of reciprocating compressor vibration conditions.
- Flexible Function Configuration: Each channel can be programmed via the 3500 rack configuration software to perform four key functions: impulse acceleration, acceleration 2, recip velocity, and low-frequency recip velocity. Channels are programmed in pairs, allowing two different or identical functions to be executed simultaneously to meet diverse monitoring needs.
- Dual Protection & Data Provision: It continuously compares monitored parameters with configured alarm thresholds to provide reliable machinery protection, while delivering essential operational and maintenance information for on-site personnel to facilitate proactive maintenance.
- Intuitive Status Feedback: Front panel LEDs (OK, TX/RX, Bypass) provide real-time visual feedback on the monitor’s operating status, including normal operation, communication with other 3500 rack modules, and bypass mode, enabling quick status identification.
- Robust & Durable Design: Featuring an epoxy-sealed construction, the monitor is built to withstand harsh industrial environments such as extreme temperatures, dust, and moisture. Its compact size and lightweight design simplify installation and integration into existing systems.
- Seamless Integration: Compatible with various PLC/DCS systems and the 3500 machinery protection system, it supports Ethernet, RS-232, and RS-485 communication ports, enabling smooth integration with supervisory systems for centralized data management.
