Our Solutions

We are specialists in the field of diaphragm seal solutions. We’re proud to say our applications are considered to be the best in industry, both in terms of durability and performance.

The often challenging and extreme process conditions for which we develop instruments, call upon our extensive knowledge to come up with highly specific solutions every time.

Extreme Temperature Solutions

Pressure measurements with extreme temperature conditions are always challenging for the pressure instrument. And thus, they are always protected with diaphragm seals to expand the temperature limits for the complete system. Whether being extreme high process temperatures for molten salt heat storage applications or furnaces, or being extreme low temperatures such as cryogenic applications, Badotherm has tailored solutions for all these situations.

Badotherm solutions go from -100°C to up to + 800°C, and a wide range of solutions in between. In the end, it is not only about the process temperature, but Badotherm also takes into account the design conditions, the material requirement to stay within the pressure temperature rating of the materials, the process pressures and measuring range as well as the ambient conditions and the eventual effect of ambient conditions to the total diaphragm seal system.

Challenging Pressure Solutions

Pressure measurements can be seen from two different perspectives. There is the static pressure that has impact on the diaphragm seal design, the materials used, the diaphragm flexibility, the compressibility of the filling fluid in the system, as well as the total mechanical integrity of the complete system, and more. Whilst Badotherm manufacturers pressure gauges up to 7000 bar, for pressure transmitters it hardly exceeds the 1000 bar static pressure. Yet, these static pressures often result in very heavy diaphragm seal constructions based on flange standard, or alternatively, specific designs such as the Hub seal designs (e.g. Galperti, Graylok, Teckloc, or Destec) or threaded seals such as the ECH type seal.

The other side there is the range or span that must be measured. For level measurements, often spans can be really small and careful engineering is needed to ensure all diaphragm seal system components are selected correctly, taking into account mounting configuration, process and ambient conditions. For this we have our Basecal software tool to easily understand the total effect of all these variables. Specific solutions for this are our compensating capillaries solution for both gauge pressure (LGP) as differential pressure (DCC – Double Compensating Capillaries).

High End Material Solutions

Diaphragm seals are often used to protect the pressure instrument from corrosive environments. Badotherm has one of the widest range of diaphragm materials available with over 22 high-end materials. Accordingly, the diaphragm seal can be manufactured in the same material as the diaphragm which is always in contact with the process and must be resistant to the process media.

Materials vary from various austenitic stainless steels (304SS, 316SS, 321SS, 347SS) to duplex (2205, 2507, 6Mo, 254SMO) as well as several alloys ( alloy 400, alloy 600, alloy 625, alloy 825) and material such as titanium, tantalum, nickel or 904L and more. Additionally very special materials such as Zirconium or Safurex, often used specifically in the fertilizer/ urea industry.

Next to this, we also can source and supply materials with specific material requirements, intergranular corrosion testing, 3.2 certification or to material standards such as NORSOK. Next to these specific high-end materials, there are also a series of solutions with specific coatings to protect the diaphragm seal materials, such as gold coatings, polymer coatings or tantaline.

Customised Solutions

Badotherm is a true end-to-end manufacturer for mechanical pressure instrumentation with a large focus on diaphragm seal systems and we design, engineer and manufacture all components in house. As such, we have extensive capabilities to design and built any type of diaphragm seals. For instance to suit specific installations for special nozzles or hook-ups. Or to replace old or specific designs that may have become obsolete or redundant because the original manufacturer has ceased a certain product line or have even ceased to exist. Yet a plant might be full of this equipment and this still needs maintenance and support. Hence Badotherm to the rescue.

We often co-innovate and design together with OEM customers to built custom design solutions as per their unique requirement. Obviously, this requires close collaboration and we do in partnership.
