Instrumentation cables are multiple conductor cables that convey low energy electrical signals used for monitoring or controlling electrical power systems and their associated processes.
These cables are used in diverse applications within industrial process manufacturing plant for control, communication, data (analog/digital) and voice transmission signals, industrial signaling and process control circuit required typically in process industries, oil, gas & petrochemical industry, fertilizers, cement, steel etc.
Introduction of microprocessor based/computerised instrumentation has demanded stringent quality requirements along with special electrical parameters for instrumentation cables. Very low level electrical signals pass between measuring end and display units/controllers which are situated far off. These low level signals are prone to external noise pickups and heavy silenuation during transmission. All this means that the cables to be used for instrumentation should be designed and manufactured very carefully, Suraj Cables with its meticulous efforts in maintaining quality, stringent in process control during manufacture and the knowledge of cable designing, is proud to say that it is capable of supplying instrumentation cables meeting any Indian/International standard or a specific requirement desired by project authority.
Instrumentation cables come with or without flame retardant properties and are suitable in process control, A/D converters and other modern microprocessor-based instrumentation circuits. These cables are designed to offer excellent resistance to noise and induction phenomena encountered in instrumentation circuits.
