Application Fields of MTL Safety Bar MTL5541

As a core safety device in industrial automation control systems, safety barriers are widely used in industrial scenarios with flammable and explosive gases, dust, or requiring electrical isolation. Their core function is to prevent explosions or safety accidents caused by electrical sparks or high temperatures by limiting energy transmission and isolating hazardous areas from safe areas.

• Refineries
  Scenario: In the process of crude oil processing and gasoline/diesel production, a large number of flammable and explosive hydrocarbons (such as ethylene, propylene, benzene, etc.) are involved.
  Role of safety barriers:
  • Isolate on-site equipment (such as sensors, actuators) from control systems in monitoring and control systems for parameters like temperature, pressure, and flow, preventing explosions caused by electrical sparks.
  • Support the HART protocol to realize remote calibration and diagnosis of intelligent valve positioners, reducing on-site operation risks.
• Chemical Plants
  Scenario: In equipment such as chemical reactors and distillation towers, flammable and explosive chemical raw materials (such as chlorine, ammonia) are used.
  Role of safety barriers:
  • Isolate hazardous areas (such as reactors) from safe areas (control rooms) to ensure safe signal transmission.
  • Provide line fault detection functions to quickly locate disconnection or short-circuit problems, improving system reliability.
• Natural Gas Processing Plants
  Scenario: In processes such as natural gas compression, dehydration, and liquefaction, high-pressure, flammable, and explosive natural gas is involved.
  Role of safety barriers:
  • Prevent electrical sparks from causing natural gas explosions in pressure monitoring, flow control, and other systems.
  • Support power supply for two-wire transmitters, simplifying on-site wiring and reducing construction costs.

• Power Plants
  Scenario: In systems such as boiler control, steam turbine monitoring, and fuel transportation, there are a large number of electrical equipment (such as generators, transformers).
  Role of safety barriers:
  • Isolate high-voltage equipment from control systems to prevent fires or explosions caused by electrical faults.
  • Ensure accurate signal transmission in parameter monitoring (such as temperature and pressure) while providing overvoltage and overcurrent protection.
• Substations
  Scenario: In monitoring systems for equipment such as high-voltage switchgear and transformers, high-voltage electrical equipment and a large number of cables are involved.
  Role of safety barriers:
  • Isolate high-voltage areas from control rooms to prevent equipment damage or casualties caused by electrical sparks.
  • Support the HART protocol to realize remote configuration and fault diagnosis of intelligent equipment.
