Product details
The FT-861 from F-tone Networks is a single-fiber 50/125 um multimode temperature sensing cable armored with a stainless steel seamless tube. The bare fiber is embedded in ointment inside the hermetically sealed tube, which resists rust and water ingress while delivering high tensile and crush resistance in a compact 4.0 mm diameter. An LSZH or PVC flame-retardant outer jacket completes the construction. Rated for -20 to +90 degrees C, the FT-861 is designed for temperature and pressure inspection in oil fields, mines and chemical plants where mechanical robustness and environmental sealing matter.
