The signal cable is designed for coiling up and spooling off the signal cable which transfers low electrical signal, such as the signal cable connecting the tensile and compression sensor. when the testing equipment is cables, avoiding abruption or pressing broken because of the cables storing irregularly, thus make sure the testing procedures can be carried on smoothly.
Structure features:1.Using differential ring to transfer the signal without contact in the cable;2.Coiler end equipped with limit protection unit to keep the differential ring safe;3. Using spiral spring power to rotate the coiler to coil up or spool off the cables automatically and intelligently without itself energy consumption. This structure keeps reliability in operation and much less worn-out.
