ESI 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.
