Two Signal Options for Pressure Measurement in Hydrogen Applications

Whether analog or digital, the DMP 336 and DCT 541 from BD|SENSORS offer two solutions for reliable pressure measurement in hydrogen applications. Both pressure transmitters feature wetted components made of special stainless steel, high overload capacity, and resistance to pressure spikes.

The key difference lies in signal transmission: The DMP 336 provides an analog 4–20 mA output, while the DCT 541 enables direct digital communication with compatible control and automation systems via its digital RS-485 interface and Modbus RTU protocol.

This allows pressure measurement to be adapted flexibly to different system architectures and process monitoring requirements – for hydrogen applications where both the selection of suitable materials and reliable signal transmission are essential.
