Isolated Signal Transmitters
As a key component of industrial control systems, isolated signal transmitters are applied in the following core industries:
DK3000 Series Isolated Signal Conditioners

I. Process Industry
Petrochemical Industry
It achieves intrinsic safety isolation in explosion-proof areas to block the risk of electric sparks in flammable and explosive environments. Meanwhile, it processes signals from temperature and pressure sensors to ensure the stable operation of the Distributed Control System (DCS).
Electric 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, rolling mills, etc., and ensures the precise control of the smelting process by the Programmable Logic Controller (PLC).
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 realizes the stable transmission of water quality parameters to the Supervisory Control and Data Acquisition (SCADA) system.
Building Automation
It converts temperature and humidity sensor signals in heating, ventilation, and air conditioning (HVAC) systems and distributes them to air conditioning units and security systems, thereby improving the efficiency of building energy consumption management.
Pharmaceutical Production
It isolates microvolt-level signals from bioreactors, ensures the safety of data collection in sterile environments, and meets the requirements of Good Manufacturing Practice (GMP) standards.
DK1200 Series Single-Phase AC Voltage & Current Isolated Signal Conditioners
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 collection in power battery factories.
Smart Factories
It is integrated into the servo system of industrial robots to isolate encoder feedback signals, thereby improving the accuracy of motion control and anti-interference capability.
Key Terminology Explanation
Isolated Signal Transmitter/Conditioner: Professional industrial equipment that realizes electrical isolation between input and output signals while completing signal conversion/conditioning, core to ensuring system stability and safety.
DCS/PLC/SCADA: Common industrial control systems-DCS for large-scale process control, PLC for discrete logic control, and SCADA for remote monitoring of distributed systems.
GMP/ESD: Industry-specific standards-GMP for ensuring pharmaceutical production quality, ESD for preventing electrostatic damage to precision electronics (critical in semiconductor manufacturing).
