RESTEST OPTION

Conductivity / Resistivity and linear resistance are intrinsically linked and it is of prime importance to know the resistivity with high precision when producing cables.

The resistivity measurement is the first step of cable production monitoring, but maybe the most critical. To be reliable, the measurement requires specific precautions. The cable preparation (extremities cutting, straighten…) and the mastery of influencing factors during measurement (temperature, environment) are crucial.

OUR OFFERING

Experimental measurement of the conductivity / resistivity of class 1 sample conductors through a true, straightforward, three steps novel solution: Resistance & Temperature Length Section (volume)

All the measurements are processed by software and the results are directly output on the display. Measurement’s uncertainties due to imperfections in sample dimensional geometric shape are eliminated, leading to an accurate determination of the conductivity / resistivity.

KEY FEATURES

Direct results without post calculation

Results based on concrete measurements

For any type of rods and drawn wires - round conductors - sector shaped conductors

Option available on any equipment of the ResTest family

Proceed with measurements directly on the production line without cutting samples. No other instrument available on the market today can offer such advantages!

OUR SOLUTION Temporary stop the production line, position and adjust the equipment towards the rope (height and slope). Tighten the jaws to centre the rope, clamp the hydraulic jaws and close the cover. Set the basic data and start the measurement. The equipment induces a known alternative current in the conductor and measures the difference of potential over a predetermined length.

The resistance is calculated from the voltage to current ration. The built-in probe measures the temperature of the conductor under test in order to display the corrected resistance value as function of to the chosen nominal temperature. The equipment measures the rope temperature and the heating elements enable the whole area surrounding the measurement setup to be brought up to the temperature of the conductor. All the heating elements are electronically regulated and controlled by microprocessor. After a few minutes only, the temperature is stabilized. A signal notifies the operator when the displayed measuring value is valid. The value can be read or printed. At the end of the measurement, the operator may remove the equipment to restart the production line.

KEY BENEFITS

Substantial time saving as cables can be directly measured while still at high temperature thanks to the innovative fast, risk free dry heating system (no water use) – no more need to wait for cables to cool down!

Significant raw material savings through ultra-smart definition of the security margin of the production machinery

Material savings as no need to test samples which will then be scrapped

Facilitated measurement directly on the production line through revolutionary technology eliminating any need for ground insulation (hazardous and unlawful) of the line

Facilitated data interpretation as the displayed measured resistance values factor in all parameters (nominal temperature, length,…) related to the measurement

Cost-effective solution provided by a

robust trolley allowing you to move and use the device on several lines

Potential savings enable a ROI within one year

The system is ISO17025 certified



RESTEST

To be reliable, measurement of the linear resistance of samples requires perfect mastery of important parameters such as temperature, length, input current, etc. This is why this measurement is generally performed in the laboratory.

OUR SOLUTION

ResTest offers a unique combination of ultra-high precision measurement with extreme simplicity of operation. All critical components are integrated (temperature sensor, calibrated measuring ruler, specific jaws for all cable types etc.) that allows you to manage and integrate measuring uncertainties.

The displayed values can be used directly (all relevant corrections are already made), printed (label or report) or exported (LAN).
