Fuji Ceramics FBS2Z5D-FC Air Bubble Sensor

Manufacturer: Fuji Ceramics Co., Ltd.
Model: FBS2Z5D-FC
Features
- An air bubble sensor detects air bubbles in liquid flowing through tubes.
- Ultrasonic waves pass through liquid but are blocked by bubbles, so bubbles are detected by changes in received signal strength.
- Because it detects without contacting the liquid, it reduces contamination risk and works with many liquids and tube materials.
