1 SIDE MOUNTING FLOAT SWITCH http: // Tel: Fax: PRINCIPLE Simple theory as liquid buoyancy is utilized for the main principle of this "FF" series. A change of liquid level correspondingly travels the float to extreme levels up and down. The reed switch is thus "NC" and "NO" exchanged as well as the permanent magnet on pivot will have mutual repellence to the other one inside on the housing for like poles, which the is buttonpushed by magnet to states "NO" and "NC" exchanging likewise. FEATURES The side mounted float level sensor ( FF series) are manufactured specifically for horizontal mounting in a tank or vessel. They work well as high or low level control. 1. Both MicroSwitch type and Reed Switch are available. The MicroSwitch type is usable even at ambient temp. of 100LC max.. Mounting flanges are custom-specifiable. (JIS, DIN, ANSI). 3. A rich variety of floats can be suited different specific gravity (S.G.) of liquid.(custom-made) 4. Liquid-wetted party material can be selected for SUS304 or SUS316 as well as enclosure explosion proof model. 55mm B 55mm WIRING COM NO NC REED SWITCH A, 30W 0Vac/00Vdc (FF0, 45, 55, 89 ) MICRO SWITCH A/50Vac 1

ANTI-ACID / ALKALINE PRINCIPLE When the solid polypropylene float is flooded by a liquid, its weight is reduced by the buoyancy of the liquid and the float moves upward.

9 ANTI-ACID / ALKALINE PRINCIPLE When the solid polypropylene float is flooded by a liquid, its weight is reduced by the buoyancy of the liquid and the float moves upward. Thus, a permanent magnet that built in the float actuates the reed switch in the sensor body to work the "NO" and "NC" exchanges. FF80EFM --- PC Housing FF81E --- Without Housing Wetted parts : P.P.

12 IMPORTANCE FOR INSTALLATION 1. SUS304/SUS316 materials is not available for corrosive application.. The cable duct(s) must face downward to prevent moisture sipping in. 3. The float and extension rod must be inserted into a bin completely. 4. Be sure the liquid object's S.G. before installation. 5. The mounting hole must be larger than the external diameter of float. 6. Don't mount the devices near the bin's inlet or outlet.
