Product NumberBE-A301
Products NameFor small diameter tubes Optical Bubble Sensor
Product detailsfor ø3 mm ø0.125 in tube
Detectable air gap0.8 mm 0.032 in or more
(Note) Sensing air gap refers to the width of an air bubble formed in the entire area of the inner diameter of the tube. Please note that this product cannot sense very small air bubbles or water drops.
Sensing objectLiquid
(Note) Sensing is affected by dirt or residues adhered to the inner wall of the tube. Please maintain the tube regularly.
Applicable tube dia. (OD×ID)ø3 mm × ø2 mm
ø1/8 in × ø1/16 in
(Note) When using a tube out of specifications or it doesn't have a smooth surface, please test sensing on the actual machine before use.
Applicable tube typeTransparent resin tube (equivalent to PFA)
(Note) When using a tube out of specifications or it doesn't have a smooth surface, please test sensing on the actual machine before use.
