  • Determining the Right Cable Length and Output for a Sensor

    If you’re monitoring a bridge or automating a machine, a high precision sensor is a great solution, but it’s no good if the output signal can’t reach the data logger. Depending on what you need to measure and what environment you’re in, determining how long your cable must run can be crucial. High precision sensors offer three common output types: analog, digital and ...

  • Panama Canal: Boat Towed 3D Resistivity Surveys - Case Study

    The Panama Canal Authority (ACP) needed to expand the canal in order to accommodate larger ships (and more traffic)—but first, they needed to know two things: what types of sediment loads needed to be dredged out—and more importantly—how much these loads would cost. That’s where AGI marine resistivity imaging ...

  • Can I monitor multiple points on one datalogger?

    Yes – using the Ebro EBI-310 USB datalogger you can monitor up to 3 points with one unit. The logger has a built in sensor, but by adding an adapter and external probes the one unit can monitor the temperature of up to 3 locations. This could mean monitoring the laboratory room temperature, ...

  • Wireless monitoring and control – where did it come from and where is it going?

    The benefits of digital network monitoring and control systems are widely acknowledged. Reduced cabling complexity, reduced installation costs and the desire to obtain increased levels of information from the plant have all contributed to thedevelopment and adoption of the technology since the second half of the twentieth century. With the introduction of its first Pakscan system in 1984 – ...

  • Compare active and passive cables

    Active cables refer to the cable with electronic part in the cable. Control and ADC in resistivity system controls the electronic parts in the cable, which controls the current injection. Passive cables refer to the cable with no electronic part in the cable. One of the advantage of passive cables is its ability to borehole and marine surveys, operator can put passive cables in water. Putting ...

  • Roll along resistivity survey

    A roll-along survey is a method for operator to survey a long line. After the initial survey, the operator will leave one cable on the ground and move the instrument and cables forward. So there is always one cable overlap between two surveys. Alternatively, the operator can divide the cable in half and only overlap 16 electrode spacing. In this way, the opearator could complete the survey ...

  • Compare popular resistivity meters with FlashRES

    Although most resistivity meters nowadays can collect resistivity, IP and SP data and most of these systems are multi-channal resistivity meters, there is still a technical gap between traditional and next generation resistivity meters. FlashRES has six to 8 times more channel than traditional system, this means larger data quantity, which could help the resistivity inversion image ...

  • The exploration depth of FlashRES resistivity meter

    The formula for calculating the maximum depth is universal for all resistivity meters. The exploration depth depends on the survey line length. the survey depth is usually 20-25% of the survey line total length. For example, for 10m takeout cables, the total length of the cable is 10m*63=630m and this means the exploration depth is 0.2*630m to 0.25*630m. The resolution is 10% of ...

  • Surface-point resistivity survey - Case Study

    Drilling boreholes for exploration can be cost ineffective and time consuming. Doing surface-point resistivity survey can provide fast and accurate results, with known position of the target, FlashRES can utilize its electrodes in borehole to target the position of the target, this enables operators to have a good understanding of the interested area. Surface-point resistivity method can also ...
