Description

01 / SENSOR PROFILE

PR6425/010-100 CON021 combines a 16 mm non-contact eddy current sensor with the matching CON021 signal converter. The sensor delivers 4 V/mm nominal sensitivity across a ±2.0 mm static linear range. It is designed for displacement measurements on ferromagnetic shafts with a reference air gap of approximately 2.6 mm. The high-temperature sensor assembly supports continuous service up to 380 °C. Its stainless-steel sleeve and PTFE cable suit demanding turbomachinery installations.

02 / SYSTEM ROLE

The system supports radial and axial shaft displacement, position and eccentricity monitoring on critical rotating equipment. The CON021 converter conditions the sensor signal for connection to compatible machinery protection and condition monitoring systems. Its wide dynamic bandwidth also supports speed and key-signal applications where the installation design requires them. The sensor and converter must be matched to the required cable length and extended measurement range. Correct mounting gap, target material and cable routing are essential for reliable measurement.

FAQ

How should PR6425/010-100 CON021 be paired for the extended measuring range?

Use the PR6425 sensor with the matching extended-range CON021 converter and the specified total cable length. The standard and extended-range converter configurations are not interchangeable without verification.

Which target material is used to calibrate PR6425/010-100 CON021?

The reference target is ferromagnetic steel, with 42CrMo4 used as the standard material. A different shaft material can change sensitivity and linearity.

Can PR6425/010-100 CON021 monitor both radial and axial shaft movement?

Yes. The sensor system is designed for radial and axial displacement, position and eccentricity measurements on critical turbomachinery.

What installation gap should be set for PR6425/010-100 CON021?

The nominal reference air gap is approximately 2.6 mm. Final alignment must remain within the calibrated linear range and follow the machine installation design.

When will PR6425/010-100 CON021 ship after payment?

Confirmed stock is prepared for dispatch immediately after payment. Typical delivery is 3–7 days by DHL, FedEx, UPS or TNT, subject to destination.

What should be checked before replacing PR6425/010-100 CON021?

Confirm the complete sensor code, converter range, total cable length, target material, mounting thread and system input requirements before installation.
