Applied Measurements DSCUSB strain gauge signal digitiser is a USB load cell interface designed to convert strain gauge transducer inputs into a digital USB serial output.  It is very compact and housed in a rugged plastic case rated to IP50 making it suitable for all indoor environments.

Our DSCUSB load cell interface plugs directly into your PC and requires no additional power supplies, as it derives all its power requirements directly from the USB bus.

The USB strain gauge signal digitiser interface utilises the ASCII protocol and features high resolution to 1 in 200,000, 7-point sensor linearisation and high speed to 100 readings/second.

PC-based calibration of the USB load cell interface is very easy to perform using the DSC-USB Toolkit software which is supplied free of charge.  The strain gauge signal can be read directly from the sensor or input numerically using the mV/V sensitivity figures from the load cell calibration certificate.  Other features includes linearization and temperature compensation.

The free Toolkit software also features a data logging function that allows the user to log data to a spreadsheet compatible CSV file at rated up to 100Hz.

Below you can download the DSCUSB Toolkit software which allows calibration and configuration of the DSCUSB module along with monitoring and data logging.  There is also a link to download the DSCLog24 which provides up to 24 channels of live monitoring and data logging.

If you require faster higher speed readings, try our new DSCUSB-FQ fast USB load cell interface, which delivers high-speed readings of 4800 samples per second!

DSCUSB Toolkit Software

Watch the How To video for a demonstration of how to use the DSCUSB toolkit.

USB Load Cell Interface toolkit software
This page shows a large display and indicates if any error conditions are present by displaying an information box.
If the module has been allocated engineering units these may be displayed in the upper right of the LCD display.
USB Load Cell Interface toolkit trend chart software
Data will be read from the module at the Measurement Rate (up to a maximum rate of 100Hz) and added to the
trend chart. You can see the current rate at which data is added at the top right of the chart.
USB Load Cell Interface toolkit calibration software
This page allows you to calibrate the module using various methods, set limits, perform system zero and set units
