ESI's hydrogen compatible pressure sensor range

Using hydrogen as a source of energy is an emerging market. This is because using hydrogen can reduce the amount of CO2 emissions and make processes more affordable, secure and clean.

ESI have a selected range of pressure sensors that are hydrogen-compatible. They are a UK manufacturer of pressure sensors, pressure transmitters, pressure transducers, strain gauges and wireless systems. 

ESI’s product range combines versatility and environmental friendliness with the exceptional performance and stability for which they are known. 

Let’s look at their new hydrogen pressure sensor range and its features.

What is hydrogen?

Hydrogen is the most abundant chemical element. Usually found as a gas, it can be produced from nuclear power, biogas and renewable power like solar and wind. It can be burnt to generate energy. 

Hydrogen is sometimes called a clean gas because when it’s burnt, the only waste product is water vapour. No carbon dioxide is produced. So, using hydrogen in any application is ‘clean’ and contributes to the reduction of greenhouse gas emissions.

Pressure sensors must be compatible with hydrogen as its use increases.

Pressure Sensors and Hydrogen

Industrial pressure sensors (also called pressure transducers or transmitters) are used to convert pneumatic or hydraulic pressure to an electric output signal.

ESI pressure sensors are compatible with hydrogen-based applications.

Many applications now require hydrogen-compatible sensors. These include:

• Hydrogen storage
• Hydrogen production
• Hydrogen re-fuelling
• Hydrogen engines
• Marine propulsion
• Hydrogen fuel cells
• Laboratory environments
• A range of other industrial applications

ESI’s range of hydrogen compatible pressure sensors

The range includes the GS4200, GD4200-USB, HP1000, and HI2000 models.

These sensors have passed hydrogen compatibility testing based on IS0 11114-2:2017 according to European Regulations EC 79/2009 and EU 406/2010/.

Key features include:

• Pressure ranges available from vacuum to 1,500 bar
• Silicon on sapphire (SOS) sensor technology for high-performance pressure measurement
• Titanium wetted parts and non-oil-filled sensor for excellent media compatibility
• Flexible design options to meet your requirements
• Robust high integrity stainless steel housing
• Digital pressure measurement solutions available with USB range
• ATEX and DNV-GL certifications available
• Build parts either EB welded or machined in one solid titanium piece for high pressures
