Unlocking Precision: The World of High Pressure Measurement Transmitters

In countless industrial and scientific applications, precise pressure measurement isn’t just a preference—it’s a critical necessity. When those pressures soar into extreme territories, the demands on measurement technology escalate dramatically. This is where high pressure measurement transmitters come into their own, offering the accuracy, reliability, and safety required for the most challenging environments. At ESI Technology, we’ve dedicated decades to perfecting these essential instruments, pushing the boundaries of what’s possible in high-pressure sensing.

Why High Pressure Measurement Demands Specialised Solutions

Standard pressure sensors, while excellent for general applications, simply can’t withstand the immense forces and potential hazards associated with high-pressure environments. Pressures reaching hundreds or even thousands of bars (or tens of thousands of psi) require a different breed of engineering. Without specialised high pressure measurement transmitters, systems could face:

• Compromised Accuracy: Sensor diaphragms can deform permanently, leading to inaccurate readings.
• Reduced Lifespan: Materials not designed for high pressure will fatigue and fail prematurely.
• Safety Risks: Catastrophic failure of a pressure sensor in a high-pressure system can lead to explosions, leaks of hazardous materials, and severe injury.
• Temperature Challenges: High pressures often coincide with extreme temperatures, further stressing the sensor components.

This is why the design and construction of high pressure measurement transmitters are paramount, focusing on robust materials, advanced sensing technologies, and rigorous testing protocols.

The ESI Technology Advantage: Silicon-on-Sapphire for High Pressure

At the heart of ESI Technology’s leading-edge high pressure measurement transmitters lies our proprietary Silicon-on-Sapphire (SoS) sensing technology. This isn’t just a buzzword; it’s a fundamental advantage that allows us to deliver unparalleled performance in high-pressure applications.

Here’s why SoS is ideal for extreme pressures:

• Exceptional Stability: Sapphire is an incredibly stable material, maintaining its properties across wide temperature ranges and under immense stress. This translates to highly accurate and repeatable measurements, even in dynamic high-pressure environments.
• High Overload Capability: The inherent strength of the SoS structure provides superior resistance to overpressure, significantly reducing the risk of sensor damage from pressure spikes.
• Corrosion Resistance: Sapphire is chemically inert, making SoS sensors highly resistant to corrosive media often found in high-pressure chemical processes.
• Miniaturisation: The compact nature of SoS technology allows for smaller, more robust sensor designs, crucial for fitting into confined spaces or for applications where weight is a factor.

This advanced technology allows our high-pressure transmitters to provide precise measurement capabilities at pressures up to 5,000 bar (72,500 psi), covering an incredibly broad range of industrial and research needs.

Versatility for Demanding Applications: High Pressure Measurement Transmitters for Every Need

The applications requiring high pressure measurement transmitters are incredibly diverse, spanning across industries from aerospace and defence to oil and gas, hydrogen energy, and marine. ESI Technology understands this breadth of need, offering a versatile range of high-pressure solutions:

• Standard High-Pressure Transmitters: Our core HP1000 series offers robust and reliable performance for a wide array of industrial applications where high pressure is a constant.
• Digital High-Pressure Transmitters: For applications demanding advanced data communication and simplified integration, our GD4200-USB Digital Pressure Transmitter (part of our award-winning ESI-USB range) provides digital output capabilities, offering enhanced accuracy and ease of use.
• Hydrogen-Compatible High-Pressure Transmitters: The burgeoning hydrogen economy presents unique challenges due to the specific properties of hydrogen. Our HP1000H High Pressure Hydrogen Transmitters are specifically designed and tested to ensure safe and accurate measurement in hydrogen systems, from production and storage to distribution and utilisation.
• Custom-Designed Solutions: We recognise that some applications have truly unique requirements. Our expertise in “in-house” design and manufacturing allows us to develop bespoke pressure transducers and transmitters tailored to the most challenging specifications.

Safety and Compliance: Non-Negotiable in High Pressure

In high-pressure environments, safety is paramount. That’s why ESI Technology goes above and beyond to ensure our high pressure measurement transmitters meet the most stringent international standards. Many of our models come with optional ATEX/IECEx certifications for use in hazardous areas (like explosive atmospheres) and DNV GL approvals for marine and offshore applications, where harsh conditions and strict regulations are the norm.
