Instrument cables are used for instrument connection. They are used to connect various instrument equipment, such as temperature sensors, pressure sensors, flow meters, etc., to transmit signals to the control system. Control connection: used to connect various control devices, such as PLC, DCS, etc., to transmit control signals and data signals. Automation system: widely used in automated production lines and industrial control systems, used to transmit various instrument signals and control signals to achieve automated control and monitoring.
Instrument cable is a cable used to connect instruments and control equipment. It has the following advantages, structural features and uses:
MULTIPLE PAIR COPPER, PVC INSULATION, FR-PVC SHEATH INDIVIDUAL SCREEN AND OVERALL SCREEN FR LOW SMOKE HALOGEN SCREEN INSTRUMENT CABLE advantage:
Strong anti-interference ability: Instrument cables usually adopt shielded structures, which can effectively resist external electromagnetic interference and ensure the stability and accuracy of signal transmission.
Good high temperature resistance: Instrument cables are usually made of high temperature resistant materials and can work stably for a long time in high temperature environments.
Good flexibility: Instrument cables usually use small wires with soft outer sheath materials, which are easy to bend and install, and are suitable for complex wiring environments.
Structural features:
Multi-core structure: Instrument cables usually have a multi-core structure, which can transmit multiple signals at the same time to meet the connection needs of a variety of instruments and control equipment.
Shielded structure: Instrument cables usually adopt shielded structures, including aluminum foil shielding and braided shielding, to ensure the stability and reliability of signal transmission.
Corrosion-resistant materials: Instrument cables usually use corrosion-resistant outer sheath materials, which can adapt to harsh usage environments, such as chemical plants, petrochemical industries and other places.
