GD4200-USB ESI Digital Pressure Transducer

Add to Cart



The GD4200-USB Digital Pressure Transducer has been designed to measure, analyze, and record pressure directly on your computer without the need for costly I/O interface boards. The user can measure up to 16 pressure inputs simultaneously and easily create customized certificates.

The transducer is powered by the computer's USB port, data is then presented on the PC via the ESI-USB configurable Windows Interface software. IT has instant connection with auto-detection, and will configure automatically with your desktop, laptop, or Windows tablet via USB protocol. 

The GD4200-USB sample rate enables dynamic pressures to be measured with up to 21 bit resolution at user selectable speeds up to 1,000 Hz. For real-time analysis, data transferred to the PC is achieved without loss of accuracy or bandwidth. This pressure transducer is USB 2.0 compatible, the ESI-USB interface configuration and analysis software is compatible exclusively with Windows 7 (32 bit & 64bit), 8, 8.1, and 10. Data can be displayed in graphical or tabular form, with a choice of pressure units and fully adjustable scales. Data can be saved to a file or exported to Excel/PDF.

The unique Silicon-on-Sapphire sensor technology provides outstanding performance and give excellent stability over a wide temperature range. Excellent measurement accuracy provides high resolution with a precision greater than 1 in 10,000. Nine pressure ranges have been 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 scanning software. 

Each unit requires free download of the ESI-USB software and is supplied with 2m USB lead, rated to IP68, and a convenient carry case.
