318690-2 is a type of electromagnetic induction device used for measuring earth resistivity. It is an easy-to-use instrument designed for use specifically in the earth resistivity testing industry. The device can be used to measure the electrical terrain conductivity on the surface of earth or another material, typically soil. This type of instrument is often employed to determine the overall quality and condition of an area’s surface soil from an environmental and safety perspective.

This device requires no affixed cable and offers operators a high degree of freedom and accuracy while testing. The instrument is operated by connecting the power leads to a power source and then moving the device over the surface being tested. By measuring the resulting electric currents in the soil, a precise resistivity measurement can be generated. This figure can then be used to calculate the exact resistivity of the material.

318690-2 is an invaluable tool for surveyors, engineers, utility companies, and other professionals involved in earth resistivity testing. It is capable of accurately measuring the resistance of the entire surface area, as well as the ability to detect smaller localized resistivity measurements. Compared to other instruments, it is much faster to set up and can be easily carried over the land being tested.

The working principle behind the 318690-2 is based on the laws of electromagnetism. It works by applying an alternating current to the surface material being tested. This current behaves in an analogous manner to magnetic lines of force. When the device is then moved over the surface material, electric fields are generated which induce electrical currents in the soil.

This current can then be used to measure the resistivity of the material. By taking various readings from each point of the surface, a detailed map of the resistivity of the material can be formed.The instrument also makes use of the mutual inductance principle which allows for the detection of smaller, localized resistivity measurements.

The 318690-2 is an essential tool for anyone involved in earth resistivity testing. It is easy-to-use, highly accurate, and provides operators with the freedom of movement while surveying the land. By taking proper measurements of the soil’s resistivity, professional surveyors can ensure that the environment is safe and compliant with existing laws and regulations.
