BG series Ultrasonic Bubble Detector / Bubble Sensor

The BG series ultrasonic bubble detectors/bubble sensors are used to detect air bubbles in the fluid-filled plastic tubing accurately. It can identify gas and liquid states at specific locations.

The BG series ultrasonic bubble detectors offer customizable response time, allowing it to be tailored to meet the unique requirements of various applications, including medical devices, bioprocessing, industrial automation, food and beverage dosing, spraying, and lubrication.

Applications

• Medical devices such as the hemodialysis machine, organ transplantation system, the heart-lung machine, the blood pump, and microwave ablation devices.

• Biopharmaceutical processes and equipment, such as single-use systems, fermenters, cell culture equipment, vaccine production, tangential flow filtration systems, and liquid chromatograph devices.

Product Features

Easy Installation

Dry coupling with adjustable response time.

bubble detector

Non-Invasive

The BG bubble detector does direct contact with the liquid, ensuring hygienic air bubble detection.

Unaffected Detection

The BG bubble detector meeasurement accuracy is impervious to tubing and liquid color.

Multiple tubing Sizes

The BG bubble detectors are available in various tubing sizes to accommodate different tubing diameters, support sensor OEM and customization.

Multi Output Mode

The BG bubble detectors provide standard output methods designed to seamlessly integrate with the automation control system. 

Sensor Calibration

The customer support team will fine-tune the sensor parameters to match users specific requirements.

Specifications

Liquids
Water, blood, saline, beverages, gasoline, paint, etc.
Tubing Materials
PVC, silicone, PE, PUR and other materials, with smooth inner and outer surfaces and no fiber or metal woven layer inside. Ideally, the wall thickness of the tubing is 10-20% of the outer diameter. The tubing needs to be pressed to the bottom of the sensor measurement slot to guarantee close contact. Dry coupling between the tubing and sensor does not require the use of grease or other coupling agents.
Housing Material
ABS plastic
Input Voltage
5-30 VDC
Current Consumption
Less than 50mA
Working Temperature
0°C to 60°C
Storage Temperature
-20°C to 70°C
Relative Humidity
30% to 90%(No condensation)
Atmospheric Environment
No corrosive gases allowed
Self Test
Optional function. Self Test can provide self checking when the tubing is not installed in the sensor. When an external 0V input signal is supplied to the Self Test pin, the sensor status changes to gas detected and the LED indicator turns red.
