Key Features & Design Advantages

• The patented TipLoc molding creates a superior bond between the tip and body.
• The CableLoc design secures the cable with 330 N (75 lbf) pull strength.
• Optional FluidLoc cable prevents internal fluid migration along the cable.
• The 8mm diameter provides a thicker coil encapsulation for enhanced physical robustness.
• We recommend the 8mm probe for optimal resistance to physical abuse.

Frequently Asked Questions (FAQ)

• What is the main advantage of the 8mm probe? Its larger diameter offers superior ruggedness and physical protection for the sensing coil.
• Can this probe handle high-pressure environments? It has a Viton O-ring seal for differential pressure but is not pressure-tested by default.
• What is the FluidLoc option? It is a special cable construction that prevents oil or other liquids from wicking through the cable core.
• What temperature classification does it have? It complies with multiple EPL classifications (e.g., T1, T2 for Ga/Gc) as per the temperature schedule.
