• Extended Temperature Range (Cable and Connector): -51°C to +260°C (-60°F to +500°F)
• Low Temperature Caution: Exposing the probe below -34°C (-30°F) may cause premature pressure seal failure.
• Relative Humidity: Less than 3% change in Average Scale Factor (ASF) after 56 days at 93% humidity (IEC 68-2-3)
• Field Wiring: 0.2 to 1.5 mm² (16 to 24 AWG), recommended 3-conductor shielded triad cable with tinned ends

Installation and Mechanical Guidelines

• Thread Engagement: M10 x 1, maximum 15 mm length of thread engagement
• Probe Case Torque (Standard Forward Mount): Maximum 33.9 N·m (300 in·lbf), Recommended 11.2 N·m (100 in·lbf)
• Probe Case Torque (First Three Threads): Maximum 22.6 N·m (200 in·lbf), Recommended 7.5 N·m (66 in·lbf)
• Gap Setting: Set radial vibration gap to approximately -9 Vdc (1.27 mm / 50 mils)
• Wiring Practice: Use shielded triad cable and keep field wiring under 305 meters for best signal integrity
• High-Frequency Note: Longer field wiring can reduce signal roll-off; refer to frequency response graphs in the manual

Frequently Asked Questions

• What is the linear range of this probe? The linear range is 2 mm (80 mils), from 0.25 mm to 2.3 mm (10 to 90 mils).
• What gap setting should I use for radial vibration? Set the gap to -9 Vdc, which is about 1.27 mm (50 mils).
• Can I use longer field wiring without signal loss? You can run up to 305 meters (1,000 feet). For longer runs, high-frequency signal roll-off may occur.
• What is the maximum thread engagement? The M10 x 1 thread allows a maximum engagement of 15 mm.
• What torque should I apply to the probe case? For standard forward mount, the recommended torque is 11.2 N·m (100 in·lbf). The maximum is 33.9 N·m (300 in·lbf).
• Does this probe come with agency approval? The 00 option means no agency approval is required for this specific model.
• What is the probe tip material? The tip uses polyphenylene sulfide (PPS), and the case is AISI 303 or 304 stainless steel.
• How fast do you ship? We ship within 5 days using FedEx, UPS, DHL, or similar carriers.
• What is your return policy? We support 30-day returns for this product.
