Galileo Galilei once said ‘measure what is measurable and make measurable what is not so.’ Four hundred years later, this is exactly what we do. We’re a family-owned company specialised in high quality mechanical process instrumentation. Founded back in 1957 as a production- and repair shop for thermometers, today we are a leading manufacturer of Diaphragm Seals, pressure gauges, temperature gauges, thermowells, valves and manifolds. Badotherm is headquartered in the Netherlands, and employs over 225 people in seven different countries and serve the most reputed end users on a global basis. We have offices and facilities in Europe, the Middle East, India, the Far East and Americas.
Diaphragm Seals, also known as remote seals, are used to separate the pressure instrument from the hash process conditions, to protect the vulnerable measuring element. A Diaphragm Seal can be mounted to almost all pressure instruments, mostly in combination with pressure (differential) transmitters, pressure gauges or pressure switches. The use of Diaphragm Seals is typically recommended, when the process:
- Has a (extremely) high or low temperature
- Is aggressive, corrosive, toxic and/or highly viscous
- Has crystallization and/or polymerization
Or for one of many other reasons such as to replace ‘wet legs’ for liquid level measurements in pressure retaining tanks. Or for specific coatings such as gold to protect against hydrogen permeation or polymer coatings for non-stick purposes.
Diaphragm Seals Solutions
Badotherm has a strong focus on Diaphragm Seal Solutions. We develop, engineer and manufacture tailor-made solutions for the most challenging conditions in the field of Diaphragm Seal measurements. The patented HTDS solution for pressure measurement up to 600°C by means of Diaphragm Seals is a great example of this, just as the low gauge pressure (LGP) measurement of just 5 mbar-g. In addition, we also developed a web-based performance calculation tool ‘BaseCal’ for Diaphragm Seal applications, to help engineers understand the impact of Diaphragm Seals, calculated under actual process conditions.
Another Innovative Solution: Badotherm Diaphragm Seals with Zirconium for Urea Plants
Badotherm has successfully developed a safe and reliable membrane type of pressure and level measurement suitable for all urea process technologies. On stream times of already nearly two years have been achieved without any issues. This means significant costs can be avoided and additional profits can be gained with the innovative Badotherm Diaphragm Seals mounted to Transmitters. Click here for the datasheet.
