The USB220 is an external high resolution/speed USB output device. Eliminating the need for a power supply, the USB220 provides excitation voltage for the sensor via the cable plugged into the PC. The analog output of the sensors is then digitized and processed by a microprocessor using the integrated high resolution (24 bits) analog to digital converter (ADC). The on-board USB device allows the microprocessor to communicate with the PC by means of the USB link. The USB integration works hand-in-hand with SENSIT™ Test and Measurement software, which allows users to monitor the actual output of the sensor in real time.
