DPA-03 Compact 3-ch Signal Conditioner

3-axis Force Sensor compatible Analog Amplifier

Smaller than the DSA-03A Amplifier. The highly functional amplifier equipped with interference correction calculation for our 3-axis force sensor.
Outputs ±5V of analog voltage.
Parameter settings and data output can be checked using the included software (*This simplified software can be used for parameter and data check only. Please use an appropriate software for measurement.)
