History and Innovation

When he discovered the measuring principle of the pressure gauge, Eugène Bourdon was searching for improvement but found a solution that would endure for centuries. Our engineers, much like Bourdon himself, continually find themselves facing challenges: getting to know the unknown and continuously optimize with intelligent solutions for your applications.

At Bourdon such challenges are addressed with inspiration and ingenuity. Our knowhow has been developed step by step with every project experience. Expertise together with the heritage passed on from Eugène Bourdon gives us a leading position in the manometer sector. Precision, excellence and the motivation to deliver a top-quality product every time are the hallmarks of our service.

When we look at what we know, we see beyond. We disregard boundaries and embrace the subject in every sense, with openness to originality and innovation. In doing this, we never lose sight of our goal to always deliver sustainable and reliable solutions. And we make sure every delivery is an original: a Bourdon. Sharing such common ground, the Bourdon Company joint the Baumer Group. Baumer now proudly holds and supplies the original Bourdon on the market, as the legacy of an inspired past and a promise for a bright future.

No secret – just a great idea

In 1849, the French engineer Eugène Bourdon patented the pressure-measuring device commonly known today as the Bourdon tube. During the construction of a steam engine, he noticed that the helically wound coil of tube used to condense the steam became flattened during fabrication. To correct this, the tube was plugged at one end and pressurized at the other. As a result, the coil began to unwind as the tube regained its circular cross-section. Intrigued by what he saw, Bourdon conducted experiments and ultimately invented a pressure gauge based on the tip deflection of a curved tube with an elliptical cross section.

Bourdon tubes are the most commonly used elastic elements in mechanical pressure gauges today, remaining popular due to their great simplicity.

The simplicity of Bourdon gauges makes them easy to operate and maintain in proper working condition. They also function across a broad pressure range and offer a high degree of accuracy (up to 0.1% full scale deflection). Since they do not require an external power source, they are not susceptible to voltage fluctuation and power outages.

Judging by the pace of technological development in today’s world, you might think that an invention from the year 1849 would have become obsolete by now. However, the Bourdon tube remains as popular as ever thanks to its many advantages.



Bourdon uses its fully internally developed Bourdon Business System (B-TraceTM) in all its production plants. Therefore it´s ensured that steady quality assurance and process optimization in production and management is in place. B-TraceTM traceability and lean process management is applied using state-of-the-art methods. 
We make the best even better
