The small 2-channel full-bridge measuring amplifier A20 has a wide range of options.
With the USB interface (A20U), it can be used for static and dynamic measurements,
with synchronous data transmission rate between 0.625..2400Hz, or by means of asynchronous measured value request.
This is also possible with the WLAN interface (A20W), but the RD version offers the option of connecting it to our Device Cloud.
The A20UMRD variant uses the mobile network for cloud connectivity and also has a USB interface.
With the RD variants (USB / WLAN), the cloud connection is not mandatory in order to be able to take measurements with the PC.
The measurement amplifier supports linear multi-point user acceleration or polynomial scaling with 4 constants.
8pcs. Output channels can be activated and assigned measured values as required.
force and weight measurements et cetera.
Linear user - multi-point scaling with 11 points, or
a polynomial user - scaling with 4 constants
