・Use M3 screws and tighten them to a torques of 0.3 N・m or less.

・When cutting the protective tubes, take care not to damage the fiber sheath.

・Amounts of light may decrease during extended periods of usage under conditions with high heat or humidity.

・Water droplets adhered to the window will influence detection performance. Avoid use in areas where direct contact with water could be made. Also pay sufficient attention to any condensation that has formed on the pipe exterior.

NF -TY01(-□)/-TY02(-□)/-TY03-TF3/
-TY05(-□)/-DY01

・Avoid use with the chemicals listed below. Chemicals that may erode PFA including fused alkali metals (sodium, potassium, lithium, etc.), fluorine gas (F2), CIF3, OF2 (including gaseous form), etc. Also, chemicals with high permeability including high temperature hydrofluoric acid, nitric acid, chlorine, etc.

NF-DY01 (heat resistant type)

・In order to protect Fiber-Optic Sensors, keep the heat resistant fiber part at least 150 mm from the boundary of the normal temperature side as shown in the diagram on the right.

・Do not directly expose Fiber-Optic Sensors to radiation heat or hot air.
