Iranian Firm Designs Micro-Ohmmeter to Measure Resistance of Switches in High Voltage Circuits
“The digital micro-ohmmeter (Contact Resistance) MOM200P is a complete device for measuring the resistance of a conductor in the range of micro Ohms when high current is applied to its two ends,” Mahnaz Moradi Qiasabadi, a member of the board of directors of the knowledge-based Tarashehpardaz Pouya company, told ANA.
According to her, the product can be used for measuring the ohmic resistance of breaker, sectioners contacts, busbar connections, machines, cables, wires and conductor connections of transmission lines, graphite generators, electric motors, aircraft bodies, railways, resistance welds, etc.
“This product performs variable current with an accuracy of -200A and -25A. The measuring range of the knowledge-based product shows between µΩ-160MΩ to -1, also the maximum VDC voltage output is -5,” Moradi Qiasabadi said.
“The consumption current A shows a maximum of 5 - and the maximum power consumption of both KW and 2 - and the knowledge-based product enjoys the capability to store 500 ohm value measurement results and the ability to store 143 ohm curve measurement results,” she added.
In a relevant development in July, technologists of an Iranian knowledge-based company stationed at the Science and Technology Park of University of Tehran had also designed and manufactured a product called ‘Bluetooth optical probe OP-740' which can receive information through an optical port from household and industrial electricity meters.
“Bluetooth optical probe OP-740 is a two-way interface based on the international standard to exchange information between the meter and the reading device,” Arash Qeylav, the managing director of the company, told ANA.
“The exchange of information between the probe and the meter is carried out through the optical port, and then the information is sent to the Android device through Bluetooth waves,” he added.
Noting that the device includes the Android library file for programmers and developers through which they will be able to establish a connection between the optical probe and their software, Qeylav said that among other advantages of the product are having an internal rechargeable battery with a large capacity, having a strong magnet to keep the probe fixed on the meter, and the possibility of downloading all the information in the meter and applying new settings to it.
“This device enjoys the capability to read different types of single-phase and three-phase digital household and industrial meters,” he underlined.
