Product Number BE-A201
Part Number BE-A201
Detectable air gap 0.8 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 object Liquid
(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) ø2 mm × ø1 mm
ø0.078 in × ø0.039 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 type Transparent 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.
