Welcome to eSI technology lImIted Hydrogen is already used in a growing variety of
SI Technology Ltd designs and manufactures pressure transducers and transmitters for the aerospace, defence, oil
and gas, subsea, medical, automotive, marine, process and general industrial markets. ESI’s product innovations include Silicon-On-
Sapphire sensor technology, the GD4200 USB transducer and the HI6000 Digitally Compensated Transmitter. ESI has also launched 2 additional product lines;
the RS-485 Series, and a hydrogen compatible pressure measurement range, offering yet more capability to ESI’s product scope.
What IS SIlIcon-on-SapphIre (SoS) SenSor technology? Incorporated throughout the ESI range, SOS combines silicon and sapphire to create a very durable sensor. Because the silicon is grown onto the surface of the sapphire it is incredibly stable and exhibits virtually no hysteresis. With its outstanding insulation properties, the sapphire protects the strain gauge from electromagnetic pulse radiation, and allows the sensor to operate over a very wide temperature range without loss of performance. It can endure high over pressures and provides superb corrosion resistance. The excellent elasticity of the sapphire ensures high repeatability which is a highly desirable characteristic for sensors.
hydrogen compatIble preSSure meaSurement The H2 range is compatible with hydrogen based environments, and is available in a general industrial, high pressure and high accuracy variant, as well as a digital transducer, available with a combination of ATEX and DNV- GL certification on selected models.

industries, and although the oil and gas sector still remains the predominant source of energy supply and usage, there are significant efforts being made to find an alternative. Applications for ESIs H2 range include:
hydrogen storage, production, re-fuelling and engines as well as marine propulsion, hydrogen fuel cells, and in laboratory environments and industrial applications.
IntroducIng the rS-485 SerIeS…. The ESI RS-485 series of high performance transducers offers pressure measurement solutions through digital, high accuracy communication. The range features a general purpose, high pressure and subsea variant. Providing a half-duplex digital RS-485 output
signal and 0-5V analogue output, the range provides high stability, repeatability, and a communication distance of up to 1,200m. With proprietary RS-485 protocol, each unit can operate up to 32 devices on the same BUS, reducing the need for expensive cabling. The range also benefits from excellent noise immunity, making it perfect for use in Programmable Logic Controllers (PLC) and industrial environments. The use of Silicon-on-Sapphire sensor
technology also provides outstanding performance and gives excellent stability over a wide temperature range. Applications for ESIs RS-485 series include:
AUV/ROVs; hydraulic systems monitoring; and oil, gas and other process liquids.
