Yocto-bridge

Yocto-Bridge

  

The Yocto-Bridge is a precision ratiometric analog/digital converter to measure over USB the very weak voltage produced by a load cell, as used in weighing scales, or any other type of strain sensor or other sensor with a Wheatstone bridge output.

The measure is performed by a 32 bit A/D with built-in preamplifier and FIR filter, which allows for a sensitiity of a few nV/V. The device includes a built-in temperature sensor, which can be internal or external NTC, to cancel temperature drift inherent to load cells, both in offset and span. The Yocto-Bridge can also apply AC excitation to cancel thermocouple effects, and perform zero tracking for simple applications where the measured signal frequently comes back to zero.

This version includes a single ratiometric inputs. If you intend to build a weighing scale with four load cells, you can use the Yocto-MaxiBridge instead, which includes four ratiometric inputs.

This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-g, it can even be connected to a GSM network thanks to the YoctoHub-GSM.
