Pressure measurement plays an important role in more applications than we can imagine. Using multiple sensor technologies, materials and fittings, we offer a product range that can measure from a few inches of water up to 5,000 bar (72,500 psi).

Accessories

The ESI product range includes high quality accessories in order to grant users the optimal installation solution in all applications.

Aerospace

Pressure transducers are involved in a number of aircraft flight testing processes. The aerospace industry worldwide demands high quality pressure transducers for such critical applications.

Automotive

The automotive industry has a number of uses for pressure transducers & transmitters. Transmission, engine, emission, brakes and exhausts are all applications that require highly accurate and reliable pressure measurement instrumentation that meets the most demanding automotive testing requirements.

Clean Rooms

Pressure transducers, usually differential, are essential for monitoring cleanroom pressures, such as filter cleanliness, airflow, and proper static pressure between the cleanroom and the adjacent space. Within the clean room space the pressure measurements taken are extremely low.

Custom Design

If our standard range wont fit the bill, our team are able to help with a custom designed solution to fit your application.

Defence

The defence industry worldwide demands high specification pressure transducers for varied but always demanding, critical applications. From aircraft to nuclear submarines, ESI Technology regularly supply pressure transducers, pressure transmitters and tachometers against MIL-Spec and NSN stock numbers.

Digital

Our digital range of pressure measurement solutions is widely supported by our award winning ESI-USB software.

General Purpose

The GENSPEC range of pressure transducers and pressure transmitters offers low cost, high quality options, with a variety of sensor technologies from proven Thick Film Strain Gauge through to high accuracy Silicon- on-Sapphire with a titanium diaphragm.

Hazardous Area

Our ATEX and IECEx approved intrinsically safe pressure transmitters provide a 4-20mA output, and are available in Gauge, Absolute, Vacuum, Differential and Compound pressure measurement format.

High Accuracy

ESI's high accuracy pressure transmitters and transducers integrate precise silicon-on-sapphire sensor technology and digital electronics, to provide high performance pressure measurement readings for test, research & calibration applications. Each unit goes through a rigorous series of testing and quality control, enabling accuracy as high as ≤ ±0.1 % of span BFSL.

High Pressure

Pressure measurement at high pressure requires a special design of sensor for high performance and safety. Silicon-on-Sapphire technology delivers with accurate, high pressure measurement up to 5,000 bar (72,500 psi) and over a wide temperature range.

High Temperature

High temperature pressure transmitters are used in applications where the media temperature exceeds the temperature limits of standard pressure transmitters, such as steam, food processing & engine monitoring.

Hydraulic

ESI offers a range of sensors that provide the highest levels of shock, vibration and overload resistance. Correct choice of hydraulic pressure transducer or hydraulic pressure transmitter delivers accurate, repeatable results with no maintenance over extended periods.

Hydrogen

The ESI Hydrogen range has special titanium alloy measurement cell and wetted parts, this material successfully passes hydrogen compatibility testing based on ISO1114-2:2017, according to the European Regulations EC 79/2009 and EU 406/2010.

Hygienic

Hygienic Pressure Sensors are demanded in some critical, sanitary and sterile applications. Markets for hygienic pressure transmitters include pharmaceuticals, petrochemicals and waste water for monitoring hydrostatic pressures to determine level, volume of tank contents or the pressure of gases generated by a process.

Low Pressure

The Low Pressure range of pressure transducers and transmitters from ESI, extends pressure sensor technology into very low pressure applications, with operating ranges as low as 0-25mbar.

Marine

Our range of DNV GL approved pressure transmitters for marine use have been developed for shipping systems such as marine engines, cargo storage tanks, fuel gauging, fresh water storage, wastewater management, heating, cooling and ballast tank control.

OEM

For a full technical specification please see below; Our sensors are available in various pressure ranges from vacuum to high pressure and with customized and electrical or pressure connections. We also offer analogue and digital interfaces.

Oil, Gas & Subsea

Silicon-on-Sapphire technology, Titanium diaphragms and full ATEX certification are just the combination that makes ESI's pressure measurement solutions a formidable choice in the oil, gas and petrochemical industry, where high accuracy and safety are imperative.

Process

The ESI range of process and industrial pressure transmitters and transducers delivers high quality solutions for high and low pressure, differential pressure, high accuracy or wireless pressure monitors for remote applications, which are all available with a selection of displays and panel meters. ATEX, IECEx and DNV GL approved versions are available.

SOS 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.

Submersible, depth & level

We can offer the complete solution to all your depth level measurement requirements. With available ranges from 1mWG to 500mWG, the ESI sensor is powered by a vented cable which can be supplied in continuous lengths of up to 500m. Depending on the application, lightening protection, non-vented cables, surge arrestors and desiccant modules may be required.

Test & Calibration

ESI pressure sensors are manufactured to meet the most demanding test and measurement specifications, from general industrial process needs up to highly specialized pressure sensors used in hazardous locations.
