Japanese Temperature Measuring Optical Cable Size Manufacturer

Leading Japanese manufacturers of temperature-measuring optical cables include Yokogawa, Japan Sensor Corporation, and Sanyo Denki, offering fiber optic and sensor-integrated cables with customizable sizes and high-precision measurement capabilities.Yokogawa Electric CorporationYokogawa produces the DTSX200 Distributed Temperature Sensor, which uses optical fiber as the sensing element to measure temperature along the entire cable length. This system allows high-resolution temperature monitoring over long distances, ideal for industrial plants, fire detection, and preventative maintenance. The optical fiber is immune to electromagnetic interference and provides precise temperature readings using the Raman scatter principle . While specific cable diameters are not listed, the system supports deployment over extensive lengths, making it suitable for large-scale installations.Japan Sensor CorporationJapan Sensor offers the FTKX Series fiber type infrared thermometers, which include a sensor head, fiber cable, and temperature converter. Users can select from over 140 customizable patterns to match their measurement requirements. The fiber cables are heat-resistant up to 150°C and allow rapid detection of temperature changes with a response time as fast as 1 ms. The system is designed for precise positioning and measurement through glass or other surfaces .Sanyo DenkiSanyo Denki manufactures the SAN-Thermo® cable-integrated multi-point temperature sensor, which embeds thermistors inside a 5 mm diameter cable. The cable supports 1 to 40 measurement points and lengths up to 100 meters, with the diameter remaining constant regardless of the number of sensors or cable length. This system is maintenance-free, continuously transmitting power and signals without battery replacement, and is cost-effective compared to traditional thermocouples or wireless sensors .Summary of Cable Sizes and FeaturesManufacturerCable TypeDiameterMeasurement PointsMax LengthTemperature Range / NotesYokogawaFiber optic (DTSX200)Not specifiedDistributed along fiberLong-distanceHigh-resolution, immune to EMIJapan SensorFiber optic (FTKX Series)CustomizableSingle-point per fiberCustomizableHeat-resistant up to 150°C, 1 ms responseSanyo DenkiSensor-integrated cable (SAN-Thermo®)5 mm1–40Up to 100 mMaintenance-free, thermistor embeddedThese Japanese manufacturers provide highly customizable and precise temperature measurement solutions suitable for industrial, laboratory, and high-voltage environments.
