Why is a leakage detector preferred over a standard signal meter for detecting leaks?

• A. It is less expensive
• B. It has a wider frequency range
• C. It requires less maintenance
• D. It has increased sensitivity to weak signals

Answer: (D)

A leakage detector is specifically designed to identify weak signals that may indicate the presence of leaks in a system. This increased sensitivity allows the detector to detect even small levels of leakage that might be overlooked by standard signal meters, which are not optimized for this particular purpose. Standard signal meters generally focus on measuring stronger signals and may not have the precision needed to identify the subtle signs of leakage. By utilizing advanced technology optimized for detecting these weak signals, a leakage detector ensures that potential leaks are caught early, helping to prevent more significant issues related to signal integrity or system performance. The other options do not directly address the primary function and capability of a leakage detector. While cost, frequency range, and maintenance are important factors in equipment choice, they do not explain why a leakage detector's sensitivity is crucial for effective leak detection in practical applications.
