Frequently Asked Questions (FAQ)

• What makes the 330750-80-05 a "High Temperature" Velomitor?
  This model operates at ambient temperatures up to +400°C under T1 classification. The hermetically-sealed case and 300 series stainless steel construction ensure reliable performance in extreme heat.
• What is the difference between the T4 and T1 temperature classes?
  The T4 rating covers -40°C to +100°C, while T1 covers -40°C to +400°C. The T1 rating is suitable for higher temperature applications such as gas turbines and exhaust systems.
• What approvals does the "-05" option include?
  The "-05" option includes CSA, ATEX, and IECEx certifications. These approvals allow installation in explosive atmospheres per Zone 0, 1, and 2 requirements.
• How do I connect this Velomitor to my monitoring system?
  Use the 2-pin Mil-C-5015 connector for a secure, hermetically-sealed connection. Pin A becomes positive relative to Pin B when velocity moves from the base to the top.
• Can I use this sensor in a submerged environment?
  No. The sensor withstands up to 100% relative humidity only in non-submerged conditions. The case is hermetically sealed but not rated for continuous submersion.
