وصف
The Bently Nevada 990-08-XX-01-00 is a specialized vibration transmitter designed for continuous monitoring of machinery vibration in industrial environments. This unit provides a reliable interface for converting transducer signals into a standard 4-20 mA output, facilitating integration with PLC, DCS, or SCADA control systems.
Features
- Designed for integration with 35 mm DIN rail mounting systems.
- Supports a wide power supply range of +12 to +35 Vdc at the transmitter terminal.
- Maximum loop resistance capability of 1,000 ohms when operating at 35 Vdc.
- Integrated current limiting feature set to 23 mA typical for circuit protection.
- Certified for use in ATEX Zone 2 hazardous locations and includes ABS maritime approval for marine-grade reliability.
Applications
This transmitter is primarily utilized in industrial rotating machinery monitoring, including pumps, fans, compressors, and motors. It is well-suited for applications where direct vibration data transmission to a control system is required without the need for a full-scale rack-based monitoring system.
