Custom Aerospace Pressure Transducers and Transmitters

ESI Technology’s Expertise in Special Products

Accurate pressure measurement is fundamental to the safe and efficient operation of modern aircraft and spacecraft. Across flight control systems, propulsion, fuel management, hydraulics and environmental control systems, pressure data is used to inform real-time decisions in safety-critical environments. ESI Technology specialises in the design and manufacture of custom pressure transducers and transmitters for aerospace applications, delivering special products engineered to meet stringent performance, environmental and regulatory requirements.

Custom Pressure Measurement for Aerospace Systems

Aerospace platforms rarely accommodate standardised instrumentation. Each application presents a unique combination of pressure ranges, temperature extremes, vibration levels, media compatibility and mechanical constraints. ESI Technology addresses these challenges through the development of application-specific pressure transducers and transmitters, designed from first principles to suit individual system requirements.

These special products are used in a wide range of aerospace pressure measurement applications, including:

• Engine and propulsion system monitoring
• Fuel and oxidiser pressure measurement
• Hydraulic and pneumatic systems
• Cabin pressurisation and environmental control systems (ECS)
• Test and qualification rigs for aerospace components

By working closely with system designers and integrators, ESI ensures that each pressure sensor delivers the required accuracy, stability and reliability across the full operating envelope.

AS9100D-Certified Aerospace Manufacturing

ESI Technology operates an AS9100D-certified quality management system, aligned with the requirements of the global aerospace and defence supply chain. AS9100D extends ISO 9001 by introducing additional controls around product safety, risk management, configuration control and full traceability—critical considerations for aerospace pressure instrumentation.

For customers, this certification provides assurance that ESI’s special products are developed and manufactured using controlled, auditable processes suitable for use in regulated aerospace environments. Design records, calibration data, inspection reports and material traceability can be supplied to support qualification, certification and ongoing airworthiness requirements.

Engineering for Extreme Aerospace Environments

Aerospace pressure transducers must maintain measurement integrity under demanding conditions, including:

• Wide operating temperature ranges
• Very high or very low pressure ranges
• High vibration and mechanical shock
• Rapid pressure cycling and transients
• Long service lives with minimal drift

ESI’s custom pressure transducers and transmitters are engineered to address these challenges through robust mechanical design, carefully selected materials and stable sensing technologies. Each special product is optimised to minimise temperature effects, reduce signal noise and maintain accuracy over extended operational periods.

Electrical outputs and interfaces can be configured to meet aerospace system requirements, including compatibility with aircraft avionics and test instrumentation.

Design, Verification and Qualification

The development of a special product at ESI follows a structured engineering process aligned with aerospace best practice. This includes:

• Detailed requirements definition and application analysis
• Design verification and risk assessment
• Prototype manufacture and performance testing
• Environmental and functional validation
• Documented calibration and final inspection

AS9100D procedures ensure disciplined change management and repeatability throughout the product lifecycle, reducing programme risk and supporting long-term aerospace deployments.

Supporting Aerospace Programme Lifecycles

Aerospace programmes often span many years, requiring stable supply, consistent performance and ongoing technical support. ESI Technology supports customers beyond initial delivery, providing lifecycle assistance, technical consultation and calibration services to ensure continued compliance and reliability.

By combining custom pressure transducer design, aerospace manufacturing expertise and certified quality systems, ESI enables engineers to specify pressure measurement solutions with confidence.

ESI Technology’s custom pressure transducers and transmitters are special products designed specifically for aerospace applications where accuracy, reliability and traceability are critical. Backed by AS9100D certification and a collaborative engineering approach, ESI delivers pressure measurement solutions that meet the technical, environmental and regulatory demands of modern aircraft and spacecraft systems.
