DG Series Pressure Transmitter For Hydrogen Application

This type of DG series pressure transmitter is especially designed for hydrogen measurement and different applications including hydrogen engines, hydrogen refuelling, hydrogen fuel cells, marine vehicles, laboratory environments. We choose special metal materials originating from the United States, which are specially designed to resist hydrogen embrittlement and hydrogen permeation. Not only is it versatile and environmentally friendly, but also provides the same great performance and stability we’re known for.

Product Detail

Product Tags


1. Hydrogen storage tank
2. Hydrogen refueling station
3. Fuel Cell Test Bench
4. Hydrogen fuel vehicle


1. One piece design and customized for the hydrogen measurement industry.
2. No oil-filled cavities leave no chance of leakage and non-welded diaphragm eliminates leak paths and weak points.
3. Imported materials are resistant to hydrogen embrittlement and hydrogen permeation.
