Areas of Use
Instrument cable is suitable for instruments and other electrical equipment in the signal transmission and control circuit.
Usedfor communicationandinstrumentationpurposes inindustries likeoil exploration, cement,paper, steel,powergenerationas well as inintrinsically safe
systems inhazardous areas likepetrochemicalplants andthermalpowerplants tomonitor measuringequipment inprocess automationapplications. HFFR
