FAQ

• What is the total probe length?
• 5.0 meters (16.4 feet).
• Can I use this probe with an 8mm Proximitor?
• No. Use only the 5 meter Proximitor Sensor.
• What happens if temperature drops below -34°C?
• The pressure seal may fail early.
• How tight should the connector be?
• Finger tight only. Max torque 0.565 N•m.
• What is the minimum shaft diameter?
• 152 mm (6.0 inches).
• Is the probe armored?
• No. This model has no armor (suffix 000).
• 经验性问答: We saw the gap voltage drift. What went wrong?
• Check cable bends. Minimum bend radius is 25.4 mm. Tighter bends cause noise and drift.
• 经验性问答: After tightening, the probe read incorrectly.
• You may have overtightened. Recommended torque is 21.1 N•m. Higher torque can damage threads or case.
• 选购指导: Which probe length should I choose?
• Match total probe length to your Proximitor. 5m probes need 5m Proximitor. Do not mix lengths.
• 选购指导: How to select thread size?
• Check your mounting hole. M16x1.5 is common. Use adapters if needed.
• 选购指导: Do I need armor?
• For dry, clean areas, no armor is fine (model 000). For rough environments, choose armored option.
