EDDY CURRENT (ECT) CONDUCTIVITY METER



  • INTRODUCTION TO CONDUCTIVITY:Electrical conductivity is the measurement of a materials ability to conduct an electric current. This is the inverse of electrical resistivity, measuring a materials ability to resist an electric current.
Conductivity in metal is established using Ohm’s Law, which states that current through a conductor between two points, is directly proportional to the potential difference across the two points. The resistance of the material, which is a constant for that material, allows the usual mathematical equation for this relationship to be true.
Conductivity is widely used to indicate material type and determine the state of heat treatment. In order to give accurate readings the SigmaCheck uses a three-point reference method. The first measurement with the probe in the air and then two further measurements are required which span the range of interest.

SIGMACHECK EDDY CURRENT (ECT) CONDUCTIVITY METER

The SigmaCheck Eddy Current (ECT) Conductivity Meter is designed to provide the user with fast and accurate conductivity measurements at a reasonable price.

The SigmaCheck EC Conductivity Meter is extremely easy to use making it suitable for use by shop inspectors or engineers.

The SigmaCheck ET Conductivity meets the requirements for conductivity measurements in the Aircraft manufacture and maintenance fields where conductivity measurements are used to verify proper alloy/temper or detect heat damaged components. The SigmaCheck Eddy Current Conductivity Meter is also useful to determine the purity of precious metals (counterfeit detection) such as gold bullion and coins.

 

The SigmaCheck ET Conductivity Meter has a standard operating frequency of 60 kHz and auxiliary frequencies of: 120, 240, 480 and 960kHz can be selected when necessary for testing thin materials with the standard probe

    The SigmaCheck EC Conductivity Meter has a large, color, LCD display that is easily seen in all lighting conditions.

    The SigmaCheck is easy to hand-hold due a sculpted housing designed to fit in your hand and a convenient size and weight; only ¾ of a pound (350g.) and measuring less than 6 ½” tall x 3 ¼” wide x 1” thick (163 x 80 x 25mm). A removable, silicon rubber boot is included to protect the instrument in rough environments. The standard Probe has been designed to comfortably fit the hand of the user.
