Leading developer of fiber optic temperature sensing and partial discharge monitoring solutions for switchgear, data centers, energy, and life sciences, delivering critical insights for electrical distribution equipment and industrial applications. The distributed temperature sensing fiber optic cable (DTS Cable) allows precise temperature measurements to be taken. The entire length of the distributed temperature sensing fiber optic cable (DTS Cable) can act as linear sensor which allows temperature measurements to be taken along it instead. Fiber optic temperature sensors are immune to the many environmental effects that compromise other measurement technologies, can be embedded and installed in locations traditional temperature sensors cannot and deliver an unprecedented level of spatial detail and data without sacrificing precision. In the field of information and communication, ZTT is dedicated to building the integrated industrial chain of optical fiber preform, optical fiber and fiber optic cable to provide customers with systematic end-to-end products and service solutions, enjoying the reputation of “home of special fiber.
