Bubbles sensors have a wide variety of applications in both medical and industrial fields. They form an integral role in keeping us safe while under treatment for illness and disease and have shaped the way in which we recover in hospitals.

 

Read on and find out more about how this often ignored piece of technology has changed the world for the better.

 

How do Bubble Sensors work?

 

Airline bubble sensors work by detecting breaks in liquid flow as small bubbles in pipes using ultrasonic technology. Ultrasonic sound waves are undetectable to the human ear but sensors are able to make use of this technology to a high degree of accuracy.

 

Ultrasonic sensors are found commonly throughout the medical world and form a large piece of the puzzle in keeping patients safely monitored while in hospital. Airline bubble sensors, in particular, have a variety of uses in the medical world and are a mainstay in the process of Dialysis.

 

Why are Bubble Sensors so Important?

 

Airline bubble sensors form a vital element of a variety of medical applications and are an integral part of monitoring and maintaining the health of patients in hospitals and under the care of medical professionals worldwide. Extracorporeal blood circulation or (ECBC) for short, is the process of circulating blood outside of a patient’s body and has several applications in the treatment of patients, the most common of which being Dialysis. Dialysis filters and purifies the blood via a special machine designed to fulfil the function of failed or failing kidneys.

 

In order to ensure patients aren’t at risk while undergoing dialysis treatment, it is of paramount importance to ensure that even tiny air bubbles do not re-enter the blood circuit. When an air bubble enters the bloodstream, it is known in the medical world as an air embolism and for patients, it can be fatal.

 

An air embolism can lead to heart failure, stroke and even respiratory issues amongst patients, in turn highlighting the importance of ensuring lines are free from air in the medical industry is crucially important.

SMD Sensors cater to a wide range of product requirements producing bubble sensors in a range of sizes from 1/16″ OD to 1/2″ OD. Additionally, they can produce sensors for piping made from a variety of materials including steel, plastic PVC, fluoropolymers including Teflon, polyethylene, nylon, silicone and glass.

 

Industrial Applications for Bubble Sensors

 

Bubble sensors aren’t only used in the field of medicine though and in fact, they perform a wide variety of functions in the world of industry too. One of the most common applications for bubble sensors in the industrial sector comes in the form of something many of us use on a daily basis, printing.

 

Utilizing piezo-electric elements, printers are able to detect small bubbles in paint and shut down in order to avoid a poor output. Via the use of complicated sensors, printers have now changed the way in which we interact with the world in numerous ways.
