Towa Seiden FSF-T-□N Reed Type Float Switch Standard Mounting Vertical Type (SUS)
Manufacturer: Towa Seiden Kogyo Co., Ltd.
Model: FSF-T-□N
Features
The reed-type float switch delivers stable level detection even in harsh tank conditions. Therefore, it maintains reliable performance despite temperature changes, steam, vapor, or internal pressure. Moreover, reed switch control operates without a power supply, which simplifies system design and reduces wiring needs.
In addition, the switch supports many liquid types by allowing flexible selection of wetted materials. For example, users can choose SUS304, SUS316, SUS316L, or corrosion-resistant resin to match specific process requirements. As a result, compatibility improves across diverse industrial applications.
Furthermore, one unit enables multi-point control, so system complexity stays low. Consequently, installation becomes easier while control efficiency increases. Overall, the reed-type float switch offers durability, flexibility, and dependable operation for liquid level management.
