Sensor cable for fibre-optic temperature measurements and for determining temperature fields or temperature anomalies caused by movements in fluids or gases encases bunched leads with fibre-optic light waveguides

摘要

An electrical heating lead (3) with an electrical resistance of 5 Ohms each kilometer and a lead with a cooling substance run next to bunched leads (2) with fibre-optic light waveguides (2.1). Hollow spaces in a cable core (4) are filled up with a cable filling compound and a lapping foil (5) surrounds the cable core. Four bunched leads surround a central strain relief (1) made from fibre glass plastic.
