As a key component of industrial control systems, isolated signal transmitters have applications covering the following core industries:
I. Process Industry
Petrochemical Industry
It achieves intrinsic safety isolation in explosion-proof areas, eliminates the risk of electric sparks in flammable and explosive environments, and processes signals from temperature and pressure sensors to ensure the stable operation of DCS (Distributed Control System).
Power Energy Industry
It converts current/voltage signals (e.g., ±100mA) from generator sets, isolates the impact of electromagnetic interference from the high-voltage side on monitoring equipment, and improves the monitoring accuracy of power grid parameters.
Metallurgical Manufacturing Industry
It isolates signals from blast furnace sensors, resists strong electromagnetic interference from arc furnaces and rolling mills, and ensures the precise control of the smelting process by PLC (Programmable Logic Controller).
II. Livelihood and Environmental Protection Fields
Sewage Treatment
It isolates signals from liquid level gauges and flow meters, suppresses interference from water pump frequency converters, and enables the stable transmission of water quality parameters to the SCADA (Supervisory Control and Data Acquisition) system.
Building Automation
It converts signals from temperature and humidity sensors in HVAC (Heating, Ventilation, and Air Conditioning) systems and distributes them to air conditioning units and security systems, improving the efficiency of building energy consumption management.
Pharmaceutical Manufacturing
It isolates microvolt-level signals from bioreactors, ensures the safety of data acquisition in sterile environments, and meets the requirements of GMP (Good Manufacturing Practice) standards.
III. High-End Manufacturing and Emerging Industries
Semiconductor Manufacturing
It isolates precise temperature signals in lithography machines and etching equipment to prevent electrostatic discharge (ESD) from damaging the wafer production control system.
New Energy Equipment
It is used for rotational speed monitoring (isolation of frequency converter frequency signals) in photovoltaic cell production lines and current acquisition in power battery factories.
Smart Factories
Integrated into the servo systems of industrial robots, it isolates encoder feedback signals to improve motion control precision and anti-interference capability.
