The DSCUSB-FQ fast USB load cell interface is a fast USB load cell interface ideal for high speed, dynamic applications. It delivers high-speed readings of 4800 samples per second with a 13-bit noise-free resolution for improved accuracy.
The DSCUSB-FQ fast USB load cell interface converts a strain gauge transducer inputs into a digital USB Serial output. It plugs directly into your PC and requires no additional power supplies, as it derives all its power requirements directly from the USB bus. The unit connects to a strain gauge transducer with a 9-way ‘D’ type socket and connects to a PC via a micro USB socket. A DIN rail mounting option is also available.
The DSCUSB-FQ fast USB load cell interface is very compact and housed in a rugged plastic case rated to IP50 making it suitable for all indoor environments.
PC-based calibration of the DSCUSB-FQ fast strain gauge digitiser is very easy to perform using the FREE downloadable FSU toolkit software. The logging software allows the capture of up to 30 minutes of data at 4800Hz (4.8kHz). In addition, the user can switch between engineering units, view a trend chart and export the data to a spreadsheet compatible CSV file.
For lower speed applications, please see our DSCUSB load cell interface which delivers high-speed readings of 100 readings per second with a high resolution of 1 in 200,000, at a lower cost.
