ESI received the title of Sensor Product of the Year at Datateams Instrumentation Excellence Awards in October 2022. Let’s take a closer look at why the GD4200-USB is quickly becoming industries leading choice for digital pressure measurement solutions…
1. Plug-in & Play
The unique “plug and play” nature of the unit allows you to be up and running viewing live pressure data within 10 minutes. The ESI-USB© software is available for direct download from our website straight to your laptop or PC, and is programmed to recognize your transducer by it’s serial number.
2. Portable
Whether you are looking to perform test and calibration, spot checks or local, direct monitoring the GD4200-USB is the convenient solution. With no need for any additional hardware or software you can test and record data on-site, and easily disconnect and move across site where and when needed.

3. SOS Sensor Technology
As with a lot of our portfolio, Silicon-on-Sapphire Sensor Technology is incorporated into the manufacture of the GD4200-USB. Because the silicon is grown onto the surface of the sapphire, the sensor exhibits virtually no hysteresis and excellent long-term stability over wide temperature ranges. The GD4200-USB meets EMC standards EN 61326-1 and EN 61326-2-3.
Advantages of SOS technology:
- Sapphire sensor element molecularly bonded to a titanium alloy sub-diaphragm
- High accuracy
- High resistance to over-pressure (proof pressure) and pressure transients
- Excellent chemical resistance
- Stable at elevated temperatures
- Pressures from -1 bar to 5000bar
- Titanium alloy wetted parts
4. Wide Pressure Range
Available in Nine pressure ranges, carefully selected to enable the user to cover any pressure that the application requires, from vacuum up to 5,000 bar, via the use of the ESI-USB© digitally self-scaling software.
5. High Speed and Accuracy
The GD4200-USB offers an accuracy of ±0.15% of span BFSL for ranges up to 3,000 bar (±0.35% above 3,000 bar), making it a strong choice for high accuracy applications. Typical thermal zero and span coefficients of the GD4200-USB are ±0.015 %FS/°C, with a ±1.5 %FS total error band from -10 °C to +80 °C. The sample rate is user selectable up to 1,000 Hz, with 21-bit resolution at up to 5 Hz and 16-bit resolution above 5 Hz.
6. Price
We all know how expensive data logging can be. The GD4200-USB transducer is an extremely cost-effective solution for monitoring and recording pressure data with no need for costly I/O interface boards.
7. The Software
In addition to the outstanding pressure measurement performance of the GD4200-USB, what really makes this product stand out is the ESI-USB© software. Freely downloadable from our website, our software includes features such as easy leak-testing, temperature analysis, and auto-updating. Our users can operate with the peace of mind that they are always running with the most up to date and optimal version of software.
8. Customized Report and Certificate Generator
Create on brand, professional test and report certification with ease. Using the ESI-USB© software you can create and save templates of personally branded test certificates and reports. These can be set up with user defined parameters, ensuring you are only ever presenting the data that’s most important to you, using your own company brand.
9. Measure 16 Inputs at Once
Through the use of a USB hub, you can detect up to 16 independent pressure sources at any one time, each identifiable by the unique transducer serial number. Of course, these can be easily re-named within the software to allow the user to easily recognize pressure data sources.
10. After-Sales Support
Our Technical Sales team are dutifully trained to know just about all there is to know about our ESI-USB. They are actively involved in the development schedule of the software and as always, are happy to help guide you through any questions you might have.
Let us offer the pressure switch or pressure transducer that best fits your application.
