The new announce of FF31N, is a special design float switch in suspended wired for sewage water tank in high speed railway carriage. This new concept allows this switch can accurate switch on/off in a tank mixing with liquid, trash, tissue, fiber and solid-phase material. Validated of BN 411002/EN 50155 standards (Vibratory strength: 20 m/s² (5 to 150 Hz) & Shock resistance: 50 m/s²).

The FF31N wired suspended float switch, aim to apply for turbidly liquid with high viscosity and contained with diversity of solid-phase material.

This sewage water tank is common for high speed railway carriage but challenge is for high standard of EMC protection. In design, the stainless coated wired acts as the switch trigger connection between a plastic float and electronic parts, whole contact parts made of non-ferroalloy material. The FF31N takes side-mounted into tank wall which supports with time delay (0.1sec -120 sec) NO / NC alarm output to detect the high/low level in sewage tank.

 

 

 

APLICATIONS

    • Application for high speed railway carriage, the FF31N can protect from over output current charge (>0.5A) to next device, owns self- diagnosis and restart function if the abnormal situation eliminated.
