Thermoelectric force (STE) tests enable a comparative assessment of the chemical composition or state of the steel structure based on the measurement of the thermoelectric force generated by contacting a heated contact electrode (copper) of the sensor with the tested material. On this basis, the identity of the chemical composition or structure with the material standard can be assessed or the quality repeatability of the inspected samples can be ascertained.

• The KARL DEUTSCH RMG 4015 crack depth meter measures the depth of cracks in iron, steel and austenitic steel components. It can also be used to measure cracks in copper, brass, aluminum and other non-magnetic metals. The principle of operation is based on a potential probe. A probe with four spring-loaded, gold-plated contact pins is placed across the crack in the material under test. Alternating current flows between the two pins through the element under test. The other two pins measure the voltage drop, on the basis of which the crack depth is estimated. The device uses an alternating voltage and a skin effect that forces the current to flow over the conductor surface and hence follow the fracture contour. The operation and the measured value are monitored by the microprocessor of the device. The measurement range is from 0 to 99.9 mm.

The FB series force gauge is designed to measure contact force and pulling force. It can also be used to measure weight. They are characterized by high accuracy and ease of use. The graphical display of the dynamometers enables easy reading of indications and presentation of measurement results in the form of histograms or charts. A special computer program for data recording and presentation gives full possibilities for the observation and measurement of variable forces. The force gauge has slings with ball joints, which enable the transfer of the measured force to the sensor and eliminate measurement errors resulting from irregular loading of the force sensor.
