Description

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.

3. Advantages and Features

Simplified Installation: DIN rail mounting and loop-powered design reduce wiring complexity.
Wide Temperature Range: Operates in extreme conditions (-40°C to +85°C), suitable for harsh environments.
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.
