How Datalink Electronics Designed and Manufactured Smart Diagnostic Systems for Leak Detection in Oil Pipelines
Client Profile / Background
Oil and gas environments present some of the harshest operational conditions for electronics: extreme temperatures, vibration, moisture, and electromagnetic interference.
The client’s main challenges included:
- Developing miniaturised electronics that could withstand high pressure and temperature inside pipeline inspection tools.
- Integrating acoustic and ultrasonic sensing electronics for real-time thickness measurement and leak detection.
- Achieving reliable data logging and signal transmission in environments where failure is not an option.
- Reducing maintenance and calibration costs through improved design robustness and component longevity.
Additionally, the client required full design-to-production support — from concept validation through to scaled manufacturing — while ensuring compliance with global standards and industry-specific safety requirements.
Datalink combined its design engineering, firmware development , and high-reliability CEM capabilities to deliver a complete electronics solution built for endurance and accuracy.
What Datalink did differently:
- Collaborative design: Our multidisciplinary team worked alongside the client’s field engineers to translate sensor performance needs into manufacturable, high-tolerance PCB assemblies.
- Custom electronics architecture: Designed ruggedised signal conditioning and acoustic sensing circuitry to detect micro-changes in sound reflections from pipeline walls, supporting real-time diagnostics.
- Environmental resilience: Used high-grade materials, conformal coatings, and advanced PCB substrates suitable for sustained high-temperature and high-vibration conditions.
- Integrated datalogging system: Developed a compact, low-power data capture module capable of recording, timestamping, and transmitting diagnostic data with fault tolerance and redundancy.
All processes were validated under AS9100 and ISO 9001 quality frameworks to guarantee compliance, traceability, and long-term reliability.
- Design & Prototyping:
Datalink’s engineering team created a series of prototype boards integrating analog signal processing, microcontroller-based data capture, and acoustic transducer interfaces. - Validation & Testing:
Each design iteration underwent thermal, vibration, and ingress protection (IP) testing to simulate downhole and rig conditions. - Process Optimisation:
Custom manufacturing jigs and automated inspection routines were developed to maintain repeatability and reduce manual handling. - Scale-Up to Production:
Following successful pilot deployment, Datalink transitioned the assemblies into volume production, maintaining full traceability and serialisation for every unit. - Collaborative Integration:
Datalink worked closely with the client’s procurement and service teams , providing consistent communication, simplified invoicing, and supply continuity planning.
