ESI Technology Ltd

Quality, technology and experience…

ESI Technology Ltd designs and manufactures pressure transducers and transmitters for the aerospace, defense, oil & gas, subsea, medical, automotive, marine, process and general industrial markets. Our customer base extends across the world, exporting 75% of our sales to more than 45 countries.

The company was formed in 1984, and has grown since that time into a worldwide supplier of "in house" manufactured pressure transducer and transmitters. Early success came from designing solutions for challenging military and aerospace applications. More recently, the outstanding quality and performance of our Silicon-on-Sapphire sensing technology, has ensured our position as one of the market leaders in the pressure measurement industry. Our comprehensive range of pressure transmitters and transducers incorporate this technology, together with the latest digital signal processing. All products are rigorously tested to ISO9001 and Mil-I-45208 procedures and conform to CE requirements. EX, IECEx and DNV GL certification is also available.

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.

Our dedicated manufacturing facility based in Wrexham, UK, provides complete control over production, and we have made considerable financial investment in product development to ensure that we are a modern business at the cutting edge of our industry.

For more than 30 years we have served our customers with consistent product development, engineered solutions and excellent technical and sales support. Our primary focus is to provide an outstanding service to customers by offering an expansive product portfolio together with a wide scope of additional services.

The Secret of Accurate and Reliable Pressure Measurement...

Pressure measurement is an important part of many applications across thousands of industries. Processes vary in pressure range, temperature and media and it can be difficult to know what sensor technology to choose for your application, but it is essential to get it right! That's where ESI comes in with a high quality solution… 

Our wide range of pressure transducers, pressure transmitters and pressure sensors incorporate the superior Silicon-on-Sapphire sensor technology to make one of the most advanced ranges available on the market.
ATEX, IECEx and DNV GL certification is available. With a range of pressures from vacuum to 5,000 bar, and various process and electrical connections.

Silicon-on-Sapphire Pressure Sensor technology

Silicon-on-Sapphire sensor technology has redefined the performance capability of ESI products.
The outstanding elastic properties of the sapphire substrate provide the perfect platform on which to create a pressure sensor with no measurable hysteresis and superb repeatability.
The measurement sensitive element consists of a silicon piezoresistive strain gauge microcircuit. The single crystal silicon forms a strong molecular bond to a sapphire substrate which is joined to a robust titanium alloy pressure diaphragm through a high temperature diffusion process. The excellent insulation properties of the sapphire allow the sensor to operate over a very wide temperature range without loss of performance.
Combined with all titanium wetted parts, this sensor offers unbeatable performance with high over pressures and excellent chemical compatibility.
