In the context of climate protection, hydrogen is increasingly gaining importance as an energy carrier. After all, hydrogen is three times as energy-rich as fossil fuels like gasoline or diesel, virtually unlimited in availability, and thus an ideal source for generating electricity and heat. However, the use of hydrogen in transport and storage requires the utmost care. This highly volatile gas has the property of diffusing into metal surfaces and causing them to spall. This impairs both measurement accuracy and long-term stability.

To minimize or prevent such hydrogen spalling in measurement technology, the correct choice of materials and the dimensioning of the basic pressure sensor are crucial. BD|SENSORS therefore offers specially designed industrial measurement transducers for use in hydrogen applications:

– DMP 336 for nominal pressures from 16 to 1,000 bar and
– DMP 333P with gold-plated membrane for nominal pressures from 60 to 600 bar

The range of hydrogen pressure sensors is now sensibly complemented by the new DCT 541 with digital output signal RS 485 or Modbus RTU protocol.

This is a consistent development of the proven pressure transducer DMP 336. Like its predecessor, the DCT 541 features media-compatible components made of special stainless steel and is highly overload-capable and resistant to pressure spikes. In oxygen applications, the special cleaning and manufacturing process ensures that residual particles and residual hydrocarbons are significantly minimized, preventing any chemical reactions during production.

Thanks to the new Modbus interface, the new pressure transducer delivers digital output signals that are easier to transmit and process.
