Sikora spark tester with removable self-test module

ACCORDING to European standards, openly operated measuring and testing equipment has to be checked regularly. Therefore, spark testers are tested with regard to the accuracy of the supplied high-voltage, the short circuit current and function (sensitivity). The Sikora spark tester Spark 6030 HF offers (optionally) a three-step self-test and calibration system including the Sikora App for mobile monitoring and analysis of the measuring results. As each test probe has to be calibrated, the testing module has to be controlled regularly as well. To support this process, Sikora developed the module of the Spark 6030 HF further. New is the easy-to-change module that combines all testing functions and which can easily be exchanged from an additional opening in the housing of the Spark 6030 HF. In order to meet the requirements of the ISO 9001 standards, Sikora recommends a yearly calibration of the spark tester by simply exchanging the test module. Due to the fact that all functions are directly mounted at the module, the complete module is exchanged for calibration. Therefore, a submission of the complete device to Sikora as well as the assignment of a service engineer is not necessary. As for the previous version of the module, the sensitivity and short Tecno Impianti Srl of Italy is a major designer and manufacturer of wire drawing machinery for different sectors of the wire industry. Its newest feature is the redesign of its successful wet wire drawing machine Model TI-310. The machine is to be utilised for production of CO 2 welding wire. It will work with a horizontal spooler and the line will be completed with coppering tank and dancer. The drawing machine Model TI-310 is equipped with 11 wet drawing passes plus one dry drawing pass at the entrance, 310mm capstan and major sized cone-holding shafts. Tecno Impianti is also present in the

circuit current tests are generated. For the sensitivity test, 20 discharges are simulated in 20 seconds. All of these discharges have to be completely detected by the spark tester. For the short circuit current test, an error caused by the contact of a user and the bead chain electrode during the operation is simulated. Here, a defined value must not be exceeded in order to guarantee the safety of the user. The calibration module measures continuously the accuracy of the testing voltage. The standard for spark testers requests an accuracy of ±5 per wire drawing machinery sector with its TR Series of straight-line multi-pass wire drawing machines, the MV Series of vertical bull-blocks, the inverted bull-block Model MVC and the MO Series of horizontal-axis wire drawing bull-blocks for CHQ wire. All its machines are designed and manufactured by the company, equipped with components of leading brands and can be offered in many different models and configurations,
