The 2 channel force / displacement measuring amplifier A212U with 3.2" touch TFT display
is a small measuring amplifier in an aluminium desktop housing. It is powered from mains voltage.

It supports a force channel (strain gauge - full bridge) and a displacement channel (TTL incremental), but can also be operated with a rotary sensor (TTL incremental) or a reflective sensor for rpm determination.
Up to 8 measured values can be displayed. The buttons can be used to tare or reset the peak values, for example.

The measuring amplifier supports linear multi-point scaling or polynomial scaling with 4 constants. Interface USB 2.0 with a synchronous data transfer rate between 0.625..1200Hz selectable, or asynchronous measured value request.
