Originally Ellison Sensors, ESI Technology manufactures and designs everything in the purpose built facility in Wrexham, UK. From this base, over three quarters of the products are exported around the globe to all the major industrialised countries. ESI Technology pressure transducers and pressure transmitters were originally designed for challenging aerospace and military applications. A variety
of technologies have been used according to the application but nowadays the Silicon-on-Sapphire technology is the jewel in the crown. Silicon-on-Sapphire technology gives superior performance to older construction methods and combined with a titanium diaphragm and all titanium wetted parts provides excellent physical and chemical resistance. That is why some of the biggest manufacturers in the aerospace industry, defence industry, automotive and subsea oil and gas choose ESI Technology pressure sensors. We believe that two- way communication between us and our customers is important. As designers and manufacturers for many years, we understand the products and help our customers to achieve the solutions they require. As both the products and the markets for them evolve we are always seeking new partners – distributors, system integrators and OEM. Pressure Transducers Pressure measurement is often conducted in critical conditions. Replacement sensor cost is sometimes not as important as reliability. That is why ESI Technology pressure transducers and transmitters are pre-conditioned for their environment. Testing is an integral part of our manufacturing processes which is why you can rely on an ESI Technology pressure sensor. Different industries have different quality standards. For example, for control valves in Subsea Control Modules ESI Technology provide hyperbaric test certificates (to 4000 metres) as standard. Environmental Stress Screening (ESS) is also offered. For hazardous areas and intrinsically safe applications ESI Technology have a range of pressure sensors with ATEX and IECEx certification for Gas Atmospheres, Dust Atmospheres and Mining. All products can be supplied with full documentation including certificates of conformity, calibration certificates, and material certificates etc. – all generated as a matter of course by our quality systems. ESI Technology works closely with local business groups and academia, completing projects with Glyndŵr University.
