The air bubble detector using special packaging technique has the advantages of long service life, high sensitivity and fast response.  Air bubble detector realizes the identification and bubble detection or liquids detection by using the different acoustic impedance of ultrasound in liquid and gas. Compared with the optical bubble sensor, the air bubble detector has no strict requirements on the color, transparency and light transmittance of the tube, and has no requirements on the light transmittance and transparency of the liquid. It can detect the bubbles of the non-transparent tube and liquid.

Siansonic provides air bubble detectors suitable for various specifications of tubes, including PVC, PP, silica gel, PTFE, PFA and other plastic materials, as well as stainless steel, titanium alloy and other metal materails. The outer diameter of infusion tube is 3mm-25mm. We also provide customized manufacturing service of tube air bubble detectors.
