Instrumentation and Signal Cable
KEI Industries Limited manufactures a wide variety of cables suitable for process instrumentation. In the projects related to power generation & distribution, chemical & fertilizer industries and various other types of engineering industries, the process instrumentation plays a vita role in measurement, supervision and control of the process. 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, KEI 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. The efforts done by KEI are reqarded by acceptance of our quality by the country’s prime organisations such as NTPC, PDIL, EIL, BHEL, TATA’s, IOCL, L&T, ABB, KRUPP Ind, BPCL., HPCL, ESSAR, SIEMENS, Electricity Boards, Reliance, IOTL, Mukand, Honeywell, etc.
