SPECIFICATIONS
Environmental resistance
Where measurement conditions have not been specied precisely, the conditions used were an ambient temperature of +23 °C
+73.4 °F.
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. Refer to the gure 1 and 2.
Sensing is affected by dirt or residues adhered to the inner wall of the tube. Please maintain the tube regularly.
When using a tube out of specications or it doesn’t have a smooth surface, please test sensing on the actual machine
before use.
Actual response time may differ from specification (typical example using applicable tube) due to dimension, light
transmission or surface state of test tube in use.
Liquid being detected should also be kept within the rated ambient temperature range.
Conrm that the power supply voltage at the end of cable is more than 4.5 V when using an extension of over 20 m 65.167 ft.
