Overview
The Bently Nevada P3403893-00416 is a two-wire vibration transmitter engineered for real-time machinery monitoring in industrial automation environments. This transmitter is designed for continuous machinery monitoring and converts vibration measurements into a 4-20 mA output signal, making integration with plant control systems seamless. It is commonly used in applications involving centrifugal air compressors, small pumps, motors, or fans. The device provides continuous vibration data acquisition, allowing maintenance teams to detect abnormal conditions before they result in equipment failure.
Key Features
- 4-20 mA Output Signal: Converts vibration measurements into a standard output signal for seamless integration with plant control systems.
- Two-Wire Design: The two-wire setup reduces installation time, complexity, and costs.
- Proximity Probe Compatible: Accepts 1 non-contacting proximity probe and extension cable.
- High Accuracy: Accuracy within ±1.5% over the specified full-scale range.
- Fail-Safe Monitoring: Output drops to less than 3.6 mA within 100 µs of a Not OK condition, restored within 2-3 seconds after condition is resolved.
- Rapid Power-Up Detection: Signal output remains less than 3.6 mA for 2 to 3 seconds after power-up to indicate the device is not ready.
Technical Specifications
- Output Signal: 4–20 mA DC
