Description
 

The new USB220 High Resolution USB Load Cell Digital Amplifier eliminates the need for an analog amplifier, power supply, and display equipment. The module is supplied by PC power through a USB Cable, providing excitation voltage for the sensor, rendering a high resolution load cell. The analog output voltage of the sensor is then digitized and processed by a microprocessor using the integrated high resolution (24 bits) analog to digital converter (ADC). The on-board USB transmitter and receiver device allow the microprocessor to communicate with the PC by means of the USB link. 

 

The USB Load Cell Amplifier works hand in hand with SENSIT Test and Measurement software, which allows users to monitor the actual output of the sensor in real time. This is calculated based on the calibration values stored in the on-board memory. The easy plug-and-play connection gives you the power to monitor the USB Load Cell interface output and enjoy measurement that is less affected by noise, temperature variation, and excitation. The USB220 USB Load Cell Digital Amplifier is designed and manufactured by FUTEK in the USA.
