Hardware Specifications

Eddy-Current Probe Operation

The probe operates as the sensing element of a proximity transducer system. It generates a signal proportional to the distance between the probe tip and a conductive target surface. When used with compatible extension cables and signal conditioning electronics, the probe supports shaft vibration, radial position, and displacement measurements.

Frequently Asked Questions

Q: Does the probe contact the rotating shaft during operation?
A: No. The 22811-00-04-10-02 uses a non-contact eddy-current sensing principle.

Q: What cable length is included with this configuration?
A: The model includes a 1.0 m integrated cable assembly.

Q: Can the probe operate as a standalone device?
A: No. It is intended to be used as part of a complete proximity transducer system.

Field Installation Guidelines

• Verify probe compatibility with the associated transducer system components.

• Maintain the specified mechanical gap during calibration.

• Route signal cables separately from motor and power wiring.

• Protect the cable assembly from excessive bending and mechanical stress.

• Perform transducer system checks before machinery startup.
