Specification notes
Q1: What is the TAKEX FLH-7013 Series?
A: The FLH-7013 Series consists of PFA-covered heat- and chemical-resistant fiber optic units for liquid level detection at ambient temperatures up to 100°C.
Q2: Which models are included in the FLH-7013 Series?
A: The series includes FLH-7013, FLH-7013-02, FLH-7013-05, and FLH-7013-1.
Q3: What is the maximum operating temperature of the FLH-7013 Series?
A: The maximum ambient operating temperature is 100°C.
Q4: What liquids can FLH-7013 detect?
A: It is suitable for liquid level detection in water, oil, and a wide range of chemical liquids.
Q5: How does FLH-7013 detect liquid level?
A: It uses a refractive sensing method that detects the optical change caused by the difference in refractive index between air and liquid.
Q6: What is the sensing tip size of FLH-7013?
A: All four models use a φ6.35 cylindrical sensing tip.
Q7: What is the difference between FLH-7013 and FL-7013?
A: FLH-7013 is the heat-resistant version, supporting ambient temperatures up to 100°C for elevated-temperature liquid level applications.
Q8: What fiber lengths are available in the FLH-7013 Series?
A: FLH-7013 uses a 1 m fiber, while FLH-7013-02, FLH-7013-05, and FLH-7013-1 use 2.5 m fibers.
Q9: Does FLH-7013 provide NPN or PNP output?
A: No. FLH-7013 is a fiber optic sensing unit and requires a compatible TAKEX fiber amplifier for electrical output.
Q10: What applications are suitable for the FLH-7013 Series?
A: It is suited to liquid level and liquid presence detection in elevated-temperature process equipment, tanks, and liquid handling systems requiring PFA chemical resistance.
