Expert Questions Answered

What makes this sensor suitable for hazardous areas?

The PR6423/002-030 carries multiple certifications including ATEX and IEC-Ex for intrinsic safety, allowing operation in potentially explosive environments with proper barriers.

How does temperature affect sensor performance?

While rated for -35°C to +180°C operation, the specified accuracy of ±0.025mm is maintained between 0-45°C, with reduced precision outside this range.

What minimum shaft size can this sensor monitor?

This 8mm probe requires a minimum 25mm diameter shaft to ensure proper magnetic field formation and accurate measurement readings.

Can this sensor measure different target materials?

While calibrated for 42CrMo4 steel, the PR6423 can measure other ferromagnetic materials with potential sensitivity variations requiring recalibration.

What cable length options are available?

Standard units include 1m cable, while custom configurations offer up to 8m lengths. Longer cables may affect system performance and require compensation.
