• Linearity Error: Less than ±0.025 mm for standard systems.
• Probe Resistance: 7.88 Ω ± 0.50 Ω at 2.0 m.
• Cable Capacitance: 69.9 pF per meter, typical.

Frequency Response and Signal Integrity

• The probe supports wide vibration frequency ranges.
• Signal roll-off depends on field wiring length.
• Maximum field wiring length reaches 305 meters.
• Shielded triad cable improves noise immunity.
• Strong resistance to electromagnetic interference.

Mechanical and Material Data

• Probe Tip Material: Polyphenylene sulfide.
• Probe Case: Stainless steel AISI 303 or 304.
• Weight: Approximately 323 g per meter.
• 3/8-24 UNF mounting thread ensures secure installation.

Temperature and Environmental Limits

• Standard Range: -52°C to +177°C.
• Extended Range: Up to +218°C at the probe tip.
• Cable and connector tolerate up to +260°C.
• Stable performance in high humidity environments.
• Scale factor drift stays below 3 percent.

Pressure and Sealing Performance
