The CG111-12 Capacitive Insulator Sensor is a high-precision sensing device designed to detect and measure the presence, thickness, or integrity of insulating materials using capacitive sensing technology. This sensor is widely used in industrial automation, quality control, and safety monitoring applications where non-contact, reliable detection of insulating layers is critical. Working Principle The CG111-12 operates based on the principle of capacitive sensing, which measures changes in capacitance caused by the proximity or properties of an insulating material. The sensor consists of an electrode that generates an electric field. When an insulating material enters this field, it alters the dielectric properties between the electrode and the ground, resulting in a measurable change in capacitance. This change is converted into an electrical signal, which can be processed to determine the presence, thickness, or uniformity of the insulator. Key Features 1. High Sensitivity – Capable of detecting minute variations in insulating materials, ensuring precise measurements even with thin or low-density dielectrics. 2. Non-Contact Operation – Eliminates mechanical wear and contamination risks, making it ideal for delicate or high-speed applications. 3. Wide Detection Range – Adjustable sensing distances allow flexibility in detecting insulators of varying thicknesses. 4. Robust Construction – Designed to withstand harsh industrial environments, including exposure to dust, moisture, and temperature fluctuations. 5. Fast Response Time – Enables real-time monitoring in high-speed production lines. 6. Analog/Digital Output Options – Supports integration with PLCs, microcontrollers, and other control systems. Applications - Quality Control – Verifies the presence and uniformity of insulating coatings on wires, PCBs, or electronic components. - Thickness Measurement – Monitors the thickness of insulating layers in manufacturing processes. - Safety Monitoring – Detects insulation degradation in cables or machinery to prevent electrical faults. - Automated Sorting – Identifies and sorts materials based on their dielectric properties in recycling or packaging systems. Advantages Over Other Sensors Unlike optical or inductive sensors, the CG111-12 excels in detecting non-metallic, non-conductive materials, making it indispensable in industries where insulators must be monitored without physical contact. Its immunity to color, transparency, or surface finish variations further enhances reliability. Conclusion The CG111-12 Capacitive Insulator Sensor offers a versatile, accurate, and durable solution for detecting and measuring insulating materials in diverse industrial settings. Its non-contact operation, high sensitivity, and adaptability make it a preferred choice for applications requiring precision and reliability in insulator monitoring.
