APCI-3300PCI board for strain gauges with a supply for each channel
- Manufacturer
The board comes in a 4-channel or an 8-channel analog version: each channel has its own voltage source, so the strain gauge bridges can be fed without external circuits.
Conversion is at 18 bits over the unipolar input range up to 1.25 V, with an amplifier programmable in software. Acquisition starts from software or from an external trigger, and optical isolation towards the field side is 1000 V.
