BENTLY NEVADA 990-04-50-01-00 2-Wire Vibration Transmitter
1. Product Description
The BENTLY NEVADA 990-04-50-01-00 is a compact, 2-wire vibration transmitter designed for continuous monitoring of rotating machinery. It converts displacement signals from non-contacting proximity probes into a standardized 4–20 mA output, enabling integration with PLC systems, DCS, or SCADA networks. With a full-scale range of 0–4 mils peak-to-peak (0–100 μm pp), this transmitter delivers precise measurements for detecting rotor vibration, misalignment, or bearing wear in critical industrial equipment.

- High Reliability: Rugged construction and EMI/RFI protection ensure stable performance.
- Cost-Effective: Direct 4–20 mA output eliminates the need for additional signal conditioning.
Case Study: A steel mill reduced unplanned downtime by 30% by using the 990-04-50-01-00 to monitor blower vibrations, enabling predictive maintenance.
4. Application Fields and Case Studies
Industries:
- Manufacturing, power generation, oil and gas, and wastewater treatment.
典型应用:
- Motors, pumps, compressors, and fans.
Case Study: A chemical plant improved agitator reliability by 25% using the transmitter to detect excessive shaft movement during operation.
5. Competitive Comparison
The BENTLY NEVADA 990-04-50-01-00 stands out due to:
- Dual-Wire Simplicity: Eliminates separate power cables, reducing installation costs compared to 3-wire alternatives.
- Wide Power Range: Accepts 12–35 VDC inputs, compatible with diverse industrial power systems.
- Extended Temperature Tolerance: Operates in colder/hotter environments than standard transmitters (typically -20°C to +70°C).
6. Selection Recommendation
- Measurement Range: Choose this model for applications requiring 0–4 mils pp vibration monitoring.
- Installation Space: Opt for DIN rail mounting if panel space is limited.
- Compatibility: Ensure compatibility with BENTLY 3300 Series probes and existing 4–20 mA systems.
7. Precautions
- Probe Calibration: Calibrate the proximity probe with the transmitter to ensure accurate measurements.
- Cable Length: Use shielded cables up to 5.0 meters (16.4 feet) to minimize signal interference.
- Loop Resistance: Verify loop resistance does not exceed 1,000 Ω to avoid voltage drop issues.
