The temperature-sensing fiber optic detector is an advanced temperature-sensing fire detector in the world, integrating high technologies such as optics, electricity, machinery, computers and weak signal detection. It can realize large-scale spatial distributed real-time temperature measurement, with the advantages of long measurement distance, no measurement blind zone, real-time monitoring and accurate positioning. It is widely used in tunnels, subways, electric power, petrochemicals, dams, oil wells and other fields. Temperature-sensing fiber optic detectors can be divided into the following categories:

I. Wall-mounted type with built-in temperature measurement module, industrial all-in-one machine, powered by 24V DC power supply. The fiber optic temperature online monitoring has functions of temperature measurement, information display, data storage, fire alarm and fire linkage, with compact structure, good stability and high reliability.

II. Cabinet-type distributed fiber optic temperature measurement: composed of a temperature-sensing fiber host, industrial fire power supply, rack-mounted industrial LCD display, storage battery and a 10-inch industrial cabinet, with functions of temperature measurement, information display, data storage, fire alarm and fire linkage, with good stability and high reliability.

III. Sensing optical cable. The sensing optical cable itself is the temperature measuring element, combining "transmission" and "sensing" in one. The sensing optical cables of Xunjie Guangtong have various structural forms such as metal armor and polymer material sheaths. The specially designed sensing optical cable not only quickly transmits external heat but also effectively protects the fiber inside the cable, suitable for the application needs of various industries.
