The DSC USB is a compact, high performance digital signal conditioner with USB connectivity aimed at applications, which require high-accuracy measurement repeatability.
The unit has a rugged ABS enclosure making it suitable for most environments. Simply by plugging the device into a PC data can be extracted from most strain gauge bridge input sensors and acquired by software. No additional power supply or amplifier modules are required. A standard ASCII protocol is used for simple communication. DSC Toolkit software is available for download to make it easier to use the DSC USB for simple applications.
Loadcell connections are via a 9 pin D connector. Full details are given in the manual.
If the DSC USB is supplied with a loadcell it will normally be calibrated to read the loadcell output in the same force units as the loadcell calibration. A traceable system certificate will be supplied for the DSC and loadcell combination. At last engineers now have a PC based force measurement system that unlike most ADC card based systems has full certified traceability.
Alternative calibrations are possible; please consult our engineering department to discuss your requirements.

Notes
- * From original offset at any time.
- ** Stability over 100 second period.
- *** A standard USB to micro USB cable is supplied with the DSC USB. A USB extension cable can be used extending the total cable length to 5m.
- FR = full range.
- RH = relative humidity.
- The DSC USB is normally supplied set to 10 readings a second and a data rate of 115200baud. The user can easily change this.
