XY-TEK's BG series ultrasonic bubble sensors can detect air bubbles in the fluid in plastic tubing, and can also detect the gas/liquid state at certain positions, which are commonly used in medical devices, bioprocessing, industrial automation, food and beverage dosing, spraying and lubrication and other fields. The sensors use ultrasonic pulse technology, and their response time and sensitivity can be flexibly modified to adapt to different application requirements.

Common applications in the field of biopharmaceuticals :

BG series sensors are suitable for various biopharmaceutical processes and equipment :

Typical application processes include : medium and buffer preparation, filtration, acid and alkali supply, inoculation, fermentation, harvest, chromatographic analysis, perfusion clarification, purification, filling, etc.

Commonly applicable equipment includes : disposable reaction containers, fermentation tanks, cell culture equipment, vaccine production, tangential flow filtration systems, liquid chromatographs, chromatographs, etc.

Common applications in other areas :

Medical devices such as hemodialysis machines, artificial hearts, organ transplant systems, blood pumps

Scientific Experiment System

Water and wastewater treatment systems

Food, beverage processing, such as milk, juice, beer production process

Filling equipment, spraying equipment, cooling system, lubrication system

Fluid monitoring during semiconductor manufacturing processes, such as high-purity water, high-purity chemical reagent transfer lines

Some technical features of the sensor include :

High precision and high stability, dry coupling, bubble detection sensitivity threshold adjustable

Non-invasive measurement, no direct contact with liquid, hygienic safety

The detection accuracy is not affected by the color of pipeline and liquid.

The circuit is integrated inside the sensor and is compact in size.

Multiple standard sizes to accommodate different pipe diameters and flexible customization

Xunyin has a series of standard size products, which are suitable for common pipeline sizes. The outer diameters of the pipes supported by the standard size products are :

1 / 8 ' ( 3.2mm )

5 / 32 ' ( 4mm )

3 / 16 ' ( 4.8mm )

1 / 4 ' ( 6.4mm )

5 / 16 ' ( 7.9mm )

3 / 8 ' ( 9.5mm )

3 / 4 ' ( 19mm )

In addition to standard size products, we can also customize for the special requirements of users.

Some specification parameters :

Measurable liquids : water, blood, normal saline, beverages, gasoline, paint, etc., do not contain or contain less solid particles

Plastic pipe material : PVC, silica gel, PE, PUR and other materials hose, inner and outer surface is smooth, the internal does not contain fiber or metal braided layer. Ideally, the wall thickness of the hose is 10-20 % of the outer diameter. The hose needs to be pressed to the bottom of the sensor measuring groove, so that the hose and the shell are in close contact to avoid loosening. If it cannot be in close contact, the ultrasonic signal cannot pass, and the bubble cannot be detected correctly. There is no need to use grease or other coupling agents for dry coupling between the hose and the sensor.

Shell 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 gas

SelfTest : optional function. SelfTest can provide self-state detection when the sensor is not installed with a hose. When an external 0V input signal is provided, the sensor state is detected gas and the LED light is red.

In addition to BG series sensors, Xunyin Technology also provides a variety of ultrasonic flow sensors and equipment. If you have any questions, please contact our 021 33885752, info @ xy-tek.cn or visit our official website www.xy-tek.cn for more details.
