Application of MTL safety barrier in refinery complex
Time: 2024/12/6 Posted: Shenzhen Hengyo Power Technology Co., Limited
The safety barriers of the No. 3 catalytic cracking unit and continuous reforming gasoline and diesel hydrogenation unit in a certain refinery use MTL5500 series guide rail installed isolation safety barriers produced by MTL company. The main models selected are as follows: MTL5516C is mainly used for switch input, dual channel, and has online detection function. MTL5514D is mainly used for switch input and circuits that require "one input and two outputs": MTL5541 is mainly used for analog input; MTL5575 is mainly used for transmitting thermocouple or thermistor signals; ICC312 (isolator) is mainly used for distributing analog signals of 4-20mA; And MTL5521 (switch output), MTL5531 (Bently eddy current probe signal input), MTL5546Y (analog signal output), MTL5576-THC (thermocouple signal input, dual channels can also be configured as one in two out).
Since the start-up of the joint device, the safety barrier system has been operating well with a low failure rate, easy installation, relatively simple maintenance, and no faults that affect the overall system have occurred; Therefore, the MTL5500 series isolated safety barrier was successful in this application.
