SUCO - Robert Scheuffele GmbH offers a range of compact and robust pressure switches (NO, NC, CO) suitable for applications using hydrogen, with a variable pressure range of 0.1 - 400 bar, which are made of stainless steel SAE 316L. There are models with different threads and also a variant with an installed cable.

Silicon on Sapphire (SOS) pressure sensors are ideal for hydrogen applications.
The technology of the sensing element is based on a thin sapphire plate of monocrystalline structure, on which a Wheatstone bridge of silicon is created by the epitaxial method. The latter is characterized by excellent mechanical and thermally stable properties and minimizes unwanted parasitic effects, which has a positive impact on accuracy and stability. In connection with the titanium membrane, a unique interplay is created, which enables high temperature and long-term stability.

These hydrogen switches must meet strict requirements to be hydrogen resistant and also reliable and accurate. In our SUCO program, we offer special mechanical switches for hydrogen.
The GS4200H sensor is an excellent example of a Silicon on Sapphire (SOS) pressure sensor ideal for hydrogen applications. This sensor is designed to withstand the high pressure and reactivity of hydrogen, which guarantees reliable measurement of hydrogen pressure changes and efficient use of hydrogen as an alternative energy source.

SUCO pressure switches "Made in Germany" are represented in nearly every industrial sector, in which hydraulic or pneumatic pressure must be reliably and safely measured, monitored and controlled. For decades, mechanical pressure switches from SUCO have acquired an excellent reputation worldwide. Its customers include well-known manufacturers in the fields of mobile hydraulics, machine and plant construction, as well as medical and process technology.

In addition to the wide range of variants and the defined temperature resistance covering extreme conditions (NBR down to -40°C, FFKM up to +120°C), the extraordinary features of SUCO’s mechanical pressure switches also include long service life and outstanding overpressure safety.

By continuously optimizing its processes and components, SUCO has succeeded in significantly increasing the already above-average overpressure resistance of its mechanical pressure switches. This was confirmed, among other things, by an external, independent test laboratory as part of a dynamic pressure change test.

A selection of mechanical diaphragm and piston pressure switches has been tested. Based on the test results, the above average overpressure resistance values of all tested pressure switches can be confirmed. Some of the series completed the entire test scenario with a total of 1.5 million cycles at various pressure levels up to max. 720 bar without failure.

Following the results, SUCO will extend the values for static overpressure strength even further. In addition, SUCO will specify values for the static burst pressure for the hex 24 and hex 27 mechanical pressure switches in future, which will reach impressive values of up to 1,000 bars.

The average burst pressure within the fluid market is approx. 20-30 % higher than the overpressure safety. With burst pressure values of up to 1.75 times the overpressure safety, SUCO switches are significantly higher, which has a positive effect on the service life and operational safety.

Thanks to this improvement, the SUCO group is taking one big step towards its vision of being one of the leading solution providers in the field of pressure monitoring and drive technology. Together with more than 65 mostly exclusive sales partners, worldwide customer service is ensured.
