Description
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!
