• Probe DC Resistance (RPROBE): 7.59 ± 0.50 Ω measured from center conductor to outer conductor.
• Frequency Response: Field wiring supports lengths up to 305 meters (1000 feet) while maintaining signal integrity.

Mechanical & Environmental Ratings

• Probe Tip Material: Polyphenylene sulfide (PPS) offers excellent durability and chemical resistance.
• Probe Case Material: AISI 303 or 304 stainless steel (SST) provides robust mechanical protection.
• Temperature Range (Standard): Operating and storage from -52°C to +177°C (-62°F to +350°F).
• Pressure Seal: Viton® O-ring effectively seals differential pressure between probe tip and case.
• Relative Humidity: Less than 3% change in Average Scale Factor (ASF) after 56 days at 93% humidity (IEC 68-2-3).

Frequently Asked Questions (FAQ)

• What does the '15' and '10' suffix indicate on this model? The '15' represents a 150 mm overall case length, while the '10' indicates a 1.0 meter total cable length, offering flexibility for various installation requirements.
• Can I use this 330103-00-15-10-02-00 in hazardous areas? Yes. With intrinsic safety barriers (per drawing 141092) or galvanic isolators, it suits Class I, Zone 0 and Class I, Division 1 locations.
• What is the difference between standard and extended temperature range probes? Standard probes operate to +177°C; extended range probes handle tip temperatures up to +218°C and cables up to +260°C.
• Does low temperature affect the probe seal? Yes, exposing the pressure seal below -34°C (-30°F) may cause premature seal failure.
