Since 1975, KELAG Künzli Elektronik AG has stood for solid expertise in sensor technology.
As the official Swiss partner of Vaisala, as well as of other selected manufacturers, we work with technologies that are deployed worldwide - and with customers who place the highest technical demands.
Our team supports projects with deep technical understanding, experience and a clear focus on the application.
Depending on the task, we supply individual sensors, complete measurement systems, or take responsibility for engineering, system design and integration.
Where standard solutions reach their limits, we develop customer-specific solutions, particularly for industrial and OEM applications.
Our aim is to deliver well-engineered, reliable and economically sound solutions -
from individual sensors to complete systems, from prototype to series production.
KELAG combines consulting, engineering and its own product development in three clearly defined business areas.
This results in reliable solutions for meteorology, industrial measurement technology and scalable OEM applications.
Measurement solutions for weather, climate, and environment.
Support for authorities, research, and operators of critical infrastructure.
Measurement expertise for industrial process environments.
Reliable solutions for quality, safety, and efficiency in operation.
Development partner for industrial sensor solutions.
Supporting OEMs from the initial idea to series production.
Today, applications in industry, environment and meteorology require state-of-the-art sensor solutions. Our experienced engineering team works closely with you to achieve this. Our extensive know-how, our comprehensive experience and engineering expertise, our wide range of products and the representation of various renowned sensor manufacturers are the best possible prerequisites for us to develop the best possible sensor solutions for you.
No matter how specific your customer's requirements may be: with us, you will find the perfect and economical solution for every requirement, tailor-made!
Meteorological and industrial measurement technology must work reliably in daily operation.
We design measurement solutions based on real-world conditions – not just on datasheets.
We provide technically sound and practical advice, with a clear understanding of engineering, operation and maintenance.
We supply proven standard products and develop customer-specific solutions – robust, pragmatic and suitable for series production.
One dedicated contact, short decision paths and direct communication – from enquiry to implementation.
Our ISO 9001:2015 certification ensures consistent quality, clear documentation and reliable processes.
The Audit StandardMany of our solutions have been in operation for years – supported by service, spare parts and ongoing support.
Get in touch nowIn addition to the distribution of state-of-the-art sensors and sensor systems, our services also include project management and engineering services for integration into existing or new systems or the implementation of system replacements.
We also provide repairs and calibrations for our products to ensure their performance and reliability. Our experienced team of technicians ensures rapid troubleshooting and minimal downtime.
Our maintenance and support service ensures a long product life and maximises the availability of your sensors and systems. Through regular maintenance intervals and fast response times in case of emergency, we ensure that your systems always function perfectly.
Thanks to our services, you can be sure that your sensors and systems are always state-of-the-art and offer optimum protection and safety. Contact us to find out more. We will be happy to help you meet your requirements.
Our sales team loves challenges! They will be happy to help you find the most suitable measuring solution for you. With us, you are choosing a reliable partner who not only wants to sell you a measuring device, but also wants to work out a solution together with you that is as economical as possible for both sides.
Some of our system solutions only exist thanks to you, i.e. thanks to specific customer requests that were finally able to prevail. With our engineering and the personal skills of the individual employees, we have been able to implement a wide variety of system solutions in Switzerland on the basis of supplier products. Since the 1990s, individual solutions have been expanded again and again or individual components have been replaced.
Highest accuracy must be maintained! To ensure the best possible, there is only one thing to do: regularly calibrate all measuring instruments. It is also advantageous to have the device calibrated by the manufacturer - our suppliers offer high-quality calibration and repair services for this purpose. So simply send your device to us for calibration and / or repair and enjoy a stress-free service. We are able to meet all original requirements and strict quality standards.
Service formIn addition to the installation and commissioning of your system, we offer maintenance and support and help you with concerns, operating questions or setting issues.
to the form
The MOWIS mobile weather station delivers precise meteorological data wherever it is needed. Fully autonomous, heated, and equipped with the proven Vaisala WXT536 weather sensor for reliable year-round operation.
The accelerometers manufactured by KELAG are based on high-precision "bulk" or "three-dimensional" micromechanical technology. In addition, internal gas damping stabilizes the measurement signal even under the most difficult conditions. The temperature response is highly stable and the hysteresis is practically unmeasurable. This highly robust technology offers the following advantages:
Step into the future: A groundbreaking new method is available to monitor your essential industrial processes. The Vaisala Indigo product family sets new standards in industrial measurement, thanks to globally leading sensor technology and a modular design. With interchangeable intelligent probes, robust transmitters, and the powerful PC software Vaisala Insight, it forms a resilient ecosystem to ensure energy efficiency, safety, and product quality in your process.
