AI Overview
The Allen-Bradley 1442-PR-0803M0505N is a
reverse-mount, 8mm eddy current probe
used for non-contact distance measurement in industrial applications like monitoring shaft vibration and position on rotating machinery such as turbines, generators, and compressors
. It works by using an eddy current system to detect changes in the sensor's impedance, which are caused by the high-frequency magnetic field's interaction with a conductive target surface.
Key characteristics of the 1442-PR-0803M0505N probe:
- Brand: Allen-Bradley (Rockwell Automation)
- Type: Reverse Mount Probe
- Probe Diameter: 8 mm (80 mils)
- Mounting Thread: M10x1
- Cable Length: 0.5 meters (1.64 feet)
How it works:
- High-Frequency Current: A driver within the system supplies a high-frequency (approximately 1 MHz) current to the probe's sensor coil, generating a magnetic field.
- Eddy Current Induction: This magnetic field induces eddy currents on the surface of the conductive target object.
- Impedance Change: The presence of these eddy currents creates a magnetic field on the target, which changes the impedance of the sensor coil.
- Signal Output: The system detects this change in the oscillator's output, which is then linearized and output as a voltage signal proportional to the distance from the target.
Applications:
- Shaft Vibration: Measuring cyclical movements of rotating shafts.
- Rotor Position: Monitoring the absolute position of rotating parts.
- Speed/Phase Reference: Providing a reference for machinery speed and phase.
- Thrust Position: Measuring the axial position of a shaft.
