The CONDUCSENS electrical conductivity measurement system operates according to the Principle of Foucault Currents: the sensor emits a high frequency magnetic field that causes Foucault currents to appear in a conductive target. These currents generate a secondary magnetic field. By capturing this secondary magnetic field, the sensor collects information about the properties of the target: its electrical conductivity, its thickness, its shape, the sensor-target distance, etc. Foucault's current method measures the electrical conductivity of a contactless material, and even through another layer of non-conducting material, which is impossible with other traditional methods.
Sciensoria's CONDUCSENS system is the only system on the market that measures the absolute value of electrical conductivity over a wide range: from 10,000 S/m (100 Wm) to 70,000,000 S/m (0.014Wm) without any prior calibration. It allows the measurement of electrical conductivity on sheets or deposits of conductive material in thin layers The measurement is accurate even at variable distance: unlike the traditional Foucault current technique, the sensor-target distance does not influence the result of the measurement. The installation is easy: the sensor may be tilted or not in contact with the target. The user-friendly measurement software works on Windows. The measurement report is generated automatically, the data can be displayed as numbers and curves ready to be inserted into the reports. It consists of a Foucault current sensor, a complex impedance analyzer (here Agilent's E4980A model), all associated with computing software implanted in a Windows XP or 7 PC.
Measuring range: 0 from 10,000 S/m (100 Wm) to 70,000,000 S/m (0.014 Wm).
Resolution: 1,000 S/m.
Compensation for target sensor distance.
The acceptable target sensor distance depends on the diameter of the sensor used.
The diameter of the sensor depends on the space reserved for it: no moving metal object must remain within a radius of 5 times the diameter of the sensor.
Measuring area diameter: 8 mm in standard version. Other values are possible.
Target shape: The target must be flat and wide enough relative to the sensor diameter (the smallest size must be at least 3 times the diameter of the sensor).
Low-thickness targets can be measured as long as this thickness is entered into the measurement software.
Stallion: without calibration
Materials: all conductive materials, graphite, metals, carbon composites.
Measurement rate: 1 to 10 measurements per second.
Operating temperatures 15 to 40 degrees Celsius.
Guarantee: The equipment is guaranteed 1 year parts and manpower, excluding sensors, cables and battery.
