Microwave barrier for level SIUR-03V2M with extremely high sensitivity in China
Microwave barrier for level SIUR-03B2.5M have extremely high sensitivity exceeding 90dB, which corresponds to the attenuation of microwave signal at a distance between the receiving and transmitting units equal to 800m.
Microwave barrier for level were developed at the request of Beijing Weifeng Technology Co., Ltd (Beijing, China) for application in dry coke quenching plants (DCQP). During comparative tests of alarms of different companies, carried out in 2022 in China, only alarms SIUR-03B2.5M provided reliable level measurement with probing through the walls of the dry quenching plants, and the thickness of the walls was up to 1m. Since then dozens of SUR-03B2.5M sets have been delivered to China, which are successfully operated at several coke production plants in China.
