With the Wellion SENSOR, you can keep an eye on your glucose levels
288 readings per day in real time, without scanning
The Wellion SENSOR is a continuous glucose monitoring (CGM) system. A measurement is taken automatically every 5 minutes (288 readings in 24 hours). Thanks to wireless data transmission, you can view your glucose readings quickly and easily in the Wellion AiDEX SENSOR app, completely discreetly – anytime, anywhere.
The system consists of three parts, all of which are necessary for monitoring your glucose levels in real time.
1. Wellion SENSOR Base: measures the tissue glucose value with the sensor thread.
2. Wellion SENSOR Transmitter: transmits the measured values to the Wellion AiDEX SENSOR App.
3. Wellion AiDEX SENSOR App: receives the measured values and displays them clearly (e.g. current value, trend arrows, target range, alarms, reports, …). The app is available for Android and iOS.
The Wellion SENSOR Base should be replaced every 10 days; the Wellion SENSOR Transmitter is reusable (with a guaranteed service life of 4 years).
How is tissue glucose measured with the Wellion SENSOR?
The Wellion SENSOR Base contains a sensor thread that is inserted under the skin into the subcutaneous fatty tissue using the applicator supplied. Here the sensor continuously measures the glucose content in the tissue fluid every 5 minutes.
The Wellion SENSOR Transmitter is attached to the Wellion SENSOR base. This is used for data transmission and is linked to the Wellion AiDEX SENSOR app. After a warm-up time of just 1 hour, you can call up your glucose value in the Wellion AiDEX SENSOR app in “real time”. The Wellion SENSOR is pre-calibrated, so no calibration by entering a blood glucose value is necessary.
The Wellion SENSOR Transmitter has a guaranteed service life of 4 years and is used again and again. Therefore, take good care of the Wellion SENSOR transmitter.
The Wellion SENSOR Base is changed every 10 days at the latest.

Values under control – with the Wellion AiDEX SENSOR app
Thanks to the continuous and automatic transfer of measured values (every 5 minutes), you can react immediately to fluctuations or gain an insight into the effect certain meals have on your glucose level.
You choose how intensively you want to use the app. You can see the most important information at a glance directly on the start screen. It shows a summary of your glucose trend and the extent to which the values for the last 6, 12 or 24 hours are within your target range.
The Wellion AiDEX SENSOR app also enables detailed data management through numerous features, giving you the opportunity to get to know your body better.

You shape your life – we’re here to support you. Start our free training video.
The training provides an introduction to the difference between tissue glucose monitoring (using the SENSOR) and blood glucose monitoring (using a conventional blood glucose meter). It then explains, step by step, how to use the Wellion SENSOR and the app. Discover how the Wellion SENSOR can improve your quality of life.
Suitable for beginners, interested users, and also the personal circle of SENSOR users (parents, partners, family carers, healthcare professionals).
Wellion SENSOR – Application Video
Installing the Wellion SENSOR – Tutorial
In this video, you can see step-by-step instructions on how to easily apply the Wellion SENSOR. Thanks to its small, flat design and the ability to choose the body site that suits you best, the CGMS sensor can also be worn very discreetly. Check your glucose levels with ease, even when you’re out and about.
Tips for everyday life
- Select a suitable wearing position for your Wellion SENSOR. Recommended areas for sensor application are the abdomen and the outside and back of the upper arm. If you wear an insulin pump, the Wellion SENSOR should be worn at least 7.5 cm away from the insulin injection site.
- Use the plaster provided to fix the Wellion SENSOR in place.
- Lying on the sensor for long periods of time squeezes the tissue, which can lead to distorted values.
- Due to the comfortable wearing comfort, you often forget that you are wearing a sensor. Change your clothes carefully and take care when drying off after showering or swimming.
- Allow the over patch to dry well between swims. The over patch should not get wet for longer than 30 minutes at a time.
- Avoid long hot baths and do not apply any creams or shower gels to the over patch. The over patchcould peel off prematurely.
- The Wellion SENSOR must not be exposed to strong magnetic fields, therefore the Wellion SENSOR Base and the Wellion SENSOR Transmitter must be removed during an MRI examination.
- CT and X-ray examinations are possible with the Wellion SENSOR.
- It is possible to go through a body scan at the airport with the Wellion SENSOR.
- Keep the Wellion SENSOR Transmitter in a safe place. It has a guaranteed service life of 4 years and will be used again and again.
- The system can be used to monitor glucose levels during pregnancy.
