Technical Specifications – Key Parameters

• Frequency Response: The probe excels in static and dynamic displacement measurements up to 10 kHz.
• Sensitivity & Linearity: Typical sensitivity is 7.87 mV/µm (200 mV/mil) with ±5% linearity over the calibrated range.
• Measurement Range: Standard linear range starts from 0.25 mm to 2.3 mm (10 to 90 mils) for most applications.
• Resolution: The system resolves displacements as small as 0.025 µm (0.01 mil) under stable conditions.
• 60 Hz Magnetic Field Immunity: At 300 Gauss, output voltage is 0.001 mil pp/Gauss at 0.5 mm gap, 0.009 at 2.5 mm, and 0.027 at 4.6 mm gap.
• Temperature Classification: For EPL Ga/Gc, T1 to T5 classes cover -55°C to +232°C; for EPL Dc, multiple T-ratings apply.
• Environmental Tolerance: Operating temperature spans -52°C to +177°C, with storage equal to operation range.
• Maximum Thread Engagement: 21 mm, ensuring strong mechanical coupling with the mounting fixture.
