Medium Frequency Conductive Pipe and Cable Locator Overview
Medium Frequency Spectrum: 8kHz – 33 kHz
Medium-frequency locators stand out as the most adaptable utility locators, performing effectively across different soil types, and capable of detecting utilities at ideal depth of upto about 9 meters.
Medium frequency conductive locators operate within the range of approximately 8 kHz to 33 kHz.
Advantages of Medium Frequencies
They strike a balance between depth penetration and signal clarity, making them versatile for a wide range of locating tasks.
They are effective for locating metallic pipes and cables, offering a good mix of range and accuracy.
Medium frequencies are less susceptible to interference from other utilities and can be used in both congested and less crowded areas.
-Good for most pipes and cables at most depths
-Direct connection and inductive signal clamps
-Reasonable distance for most locate jobs.
What types of underground utilities can be identified using Medium Frequency Conductive Pipe and Cable Locators?
Here are some examples, including those for specific locating and tracing tasks with medium frequency locators:
Medium to Large Ferromagnetic Objects: This category includes pipes and cables made from materials like iron and steel, which are highly conductive and can be detected due to their ferromagnetic properties.
Examples include:
-Medium to Large diameter steel pipelines.
-Medium to Large iron water mains.
-Steel conduit for electrical or telecommunications cables.
-Medium size and conductive materials are detectable at depths up to about 9 meters.
These utilities and objects are critical to locate accurately for construction planning, excavation work, and infrastructure maintenance to avoid damaging them and to ensure safety. The choice of detection technology depends on the specific utility type, material, and the surrounding soil conditions, which can affect signal transmission and detection depth.
