Welcome to ESI Technology, founded in 1984 and headquartered in Wrexham. From our beginnings, we’ve evolved into a worldwide leader in manufacturing “in-house” pressure transducers and transmitters. Our initial success designing solutions for challenging military and aerospace applications laid the groundwork for our global presence today.

Driven by Silicon-on-Sapphire sensing technology, we’ve solidified our position as a market leader in pressure measurement. Our range of pressure products integrates this advanced technology and digital signal processing, showcasing our commitment to innovation.

Quality is the cornerstone of our offerings. All our products undergo rigorous testing in accordance with ISO9001 and Mil-I-45208 procedures, ensuring unparalleled performance. We’re proud to uphold CE requirements, and for those seeking extra assurance, we provide EX, IECEx, and DNV GL certifications.

In 2009, the company was bought by SUCO Robert Scheuffele GmbH & Co. KG, a German based company. With similar values and methods of business, SUCO saw ESI as the perfect acquisition. SUCO is primarily in the market place fulfilling the need for high volume, low cost pressure switches and transducers.
