Pressure measurement
WHY ENGINEERS CHOOSE THE HP1000 FOR HIGH-PRESSURE MEASUREMENT
W
hen applications involve extreme pressures, engineers need equipment they can trust. High- pressure systems place enormous
demands on pressure measurement devices. As pressure levels increase, reliability, accuracy, and durability become even more important. The ESI Technology HP1000 Series meets these challenges head-on. Designed for pressures up to 5,000 bar (72,500 psi), the HP1000 combines robust construction, proven Silicon-on-Sapphire technology, and a range of certification options. As a result, it performs reliably in some of the world’s most demanding environments.
BUILT FOR EXTREME PRESSURE APPLICATIONS
The HP1000 Series uses a unique one-piece titanium sensing assembly. Unlike many conventional pressure transmitters, the diaphragm and pressure housing come from a single piece of titanium alloy. This design removes welded joints from the pressure boundary. Consequently, it increases strength, improves long-term reliability, and helps the transmitter withstand pressure spikes and transients. In addition, titanium offers excellent corrosion resistance. Therefore, the HP1000 performs well in harsh industrial environments where durability matters.
THE BENEFITS OF SILICON-ON-SAPPHIRE TECHNOLOGY
At the heart of the HP1000 lies ESI’s Silicon-on- Sapphire (SOS) sensor technology. SOS technology provides excellent long-term stability and accuracy, and delivers reliable performance across wide temperature ranges. This makes it ideal for demanding applications where environmental conditions can change rapidly. The sapphire substrate provides outstanding electrical insulation. As a result, the sensor maintains consistent performance even in challenging operating conditions. Together, these benefits help engineers achieve accurate pressure measurements over the lifetime of the product.
SUPPORTING THE GROWING HYDROGEN INDUSTRY
As hydrogen technologies continue to expand, pressure measurement equipment must meet new challenges. To support this growing market, ESI offers the HP1000H, a hydrogen-compatible version of the HP1000 Series. ESI designed this model specifically for use in high-pressure hydrogen applications. The HP1000H uses hydrogen-compatible titanium wetted parts and undergoes testing in accordance with ISO 11114 standards. In

addition, ESI supplies hydrogen-approved units with a certificate confirming their hydrogen compatibility. These features make the HP1000H an excellent choice for hydrogen storage systems, refuelling stations, test facilities, and distribution infrastructure.
ATEX AND IECEX CERTIFICATION OPTIONS
Many high-pressure applications operate in hazardous areas. Therefore, safety certification often plays a critical role in product selection. The HP1000 Series offers optional ATEX and IECEx Intrinsically Safe approval on 4-20 mA versions. These approvals support installation in hazardous gas, dust, and mining environments. As a result, engineers can specify the HP1000 with confidence when working in potentially explosive atmospheres.
DNV APPROVAL FOR MARINE APPLICATIONS
The HP1000 Series also offers DNV approval for marine and offshore projects.
This certification helps simplify equipment selection for shipbuilders, offshore operators, and marine system integrators. Furthermore, it demonstrates the product’s suitability for demanding maritime environments.
For organisations working within classification requirements, DNV approval can reduce qualification work and streamline project approval processes.
A PROVEN SOLUTION FOR DEMANDING INDUSTRIES
The HP1000 Series combines several important advantages in a single product family. It delivers high-pressure capability, robust titanium construction, Silicon-on-Sapphire technology, hazardous area certification options, and hydrogen-compatible variants.
As industries continue to push operational limits, reliable pressure measurement becomes increasingly important. The HP1000 helps engineers meet those demands while maintaining the accuracy, durability, and performance required for critical applications.
Whether the application involves industrial testing, energy systems, marine projects, or emerging hydrogen infrastructure, the HP1000 Series provides a dependable solution for high-pressure measurement. Contact the sales team for a quote:
