T-Guard Leak Detection Sensor

T-Guard works with simple chambers at atmospheric pressure, so there is no need for costly and complex high vacuum chambers and pumps. That makes automated systems based on T-Guard an attractive alternative to pressure decay and water bath leak detection, providing up to 100 times the sensitivity with low cost of ownership and high ease of use. The measurements are also highly repeatable, even with large, warm or humid test objects.

Advantages

• T-Guard Leak Detection Sensor brings increased levels of productivity, reliability and sensitivity to any stage of production when testing automotive components, valves and similar products.

Features

• Up to 100 times more sensitive than pressure decay and water bath
• Detects 3 x 10^-4 mbar l/s (0.018 sccm) in a 10 l chamber in less than 20 seconds
• Works at atmospheric pressure – no need for costly vacuum chamber or high vacuum pump
• Maintenance-free INFICON Wise Technology , proven in more than 1000 systems
• Measurements are not affected by temperature and humidity
• Simple design maximizes reliability, reduces cost of ownership
• Small and light for easy integration in any system
• Multiple measurement modes for flexibility
• Designed for automated systems
• Flexible control by PLC, PC, Profibus or optional display unit

Typical Applications

• Wherever pressure decay and water bath systems are used or are not sensitive enough
• Leak detection for room air conditioner components
• Manufacturers of automotive gas lines, small heater coils, etc. that are now demanding greater leak tightness
• Leak detection involving warm, humid or large parts, where the pressure decay method is ineffective
• Other markets where helium vacuum leak detection has been considered too costly or complex
