Overview High pressure wireless phase detector is a dedicated test high-voltage nuclear phase tester based on national power industry standard norms and market demand, and high-voltage nuclear photographic applies to detecting the two-sided circuit breaker of the ring or dual power supply power network closed loop circuit breaker. Whether it is produced in the same phase. Before the closed loop two power supply, you must perform a nuclear phase, otherwise a short circuit can occur, suitable for the 6KV ~ 220KV transmission line with the electrical core, the sight can reach 200 meters, and the wall can be used, and it has a test function. Wireless high-pressure cores use wireless transmission technology, safe and reliable operation, easy to use, in line with national electric power safety equipment quality supervision and testing standards. Compared with the cable core, it is the main advantage that the lead wire connected to both grids (power supply) is removed, and the safety is used to improve the security in a manner that is not subject to any terrain and facility architecture. Technical parameter: Phase difference Error 5 Frequency accuracy 0.1Hz The voltage grade measured by this product is 6kv-220kv Transmission distance of the transmitter and receiving host

MLC-V235 Continuous Casting Mold Level Automatic Measurement System Overview The automatic control for the molten steel level of the mold is one of the key technologies of continuous casting production. It is very important to reduce the labor intensity of workers, improve production efficiency, improve the quality and output of casting billet, reduce overflow and breakout of steel and improve the management level of steelmaking and continuous casting. The molten steel is poured into the mold. In order to prevent overflow, the molten steel level must be kept stable. Otherwise, during the casting process, if the level will fluctuate too much, and slag will be involved, forming surface slag inclusion on the surface of the casting billet, affecting the quality of the billet. The test points out that the relationship between the level fluctuation and the depth of casting billet surface slag inclusion is as follows: The experience has shown that surface slag inclusions can be eliminated when the level fluctuation is within 10mm. At the same time, if the level fluctuation is more than 10mm, the rate of longitudinal cracks on the casting billet surface is 30%. It means that the level fluctuation directly affects the surface quality of the casting billet. The principle of the system The eddy current type molten steel level gauge is the key to the system. The system operates reliably and has excellent performance: high temperature resistance, strong anti-interference ability, fast dynamic response (lag time
