The air bubble sensor is a sensor to detect bubbles and liquid outage in the liquid sending tubing. It's for devices where bubbles and liquid outage are meant to be avoided such as medical and analytical equipment, etc. Ultrasonic bubble sensors can be applied to colored tubing or opaque liquid where optical methods are incapable.
Mechanism of sensor The piezoelectric transducer on one side will produce ultrasonic waves and send them through the tubing to the opposite piezoelectric transducer which will observe the received signal strength continuously. The conductivity of ultrasonic waves is diff erent between liquid and bubbles. The ultrasonic waves will be transmitted well when there is only liquid in the tube, but when bubbles are passing, the ultrasonic waves will be blocked by the bubbles, and the received signal strength from ultrasonic waves will become weak. The ultrasonic bubble sensor makes the use of this relationship to detect bubbles.

FEATURES Sensors capable of detecting tiny bubble (φ0.83 mm /0.3 µL or more) by
using ultrasonic wave Not affected by the color of the liquid or tubing Standard equipment with digital output (by setting the threshold voltage)
and analog output Customizable according to the tubing being used
1The suffi x “” in part number (P/N) means a value of the threshold voltage. For the details, please refer to “Output” on the next page. 2P/N “OUD-2M-F050” and “OUD-2M-M100” of the above are not available as a standard lineup, so please contact us for the details. 3Tubing with a small diameter may also be possible by using an adapter tube, so please contact us.

Analog output Depending on the detected bubble size, the output voltage will decrease. The larger the bubble is, the more it decreases.
Digital output With the threshold voltage set according to the analog output voltage when the tubing is full of water, digital output will change from Hi to Low level when analog output voltage is less than the threshold voltage. The threshold voltage can be set to 0.1V, 0.2 V, 0.3 V, 0.4 V or 0.5 V.
