Part No: BE-A401P

Specifications

ItemPerformance characteristics
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)ø4 mm × ø2.4 mm
ø5/32 in × ø3/32 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 flexible PVC)
(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.
