Description
The measuring amplifier BSC8D is a DC voltage measuring amplifier with USB interface.
The resolution is 16 bit with a total sampling rate of 200kHz. The integratedA/D
measurement card NI USB 6210 has up to16 analog input channels and digital
inputs/outputs which are led outside on a 37-pin Sub-D socket.
To upgrade to 16 channels, a second, structurally identical housing without A/D measuring
card is connected to the master unit via a 37-pin flat ribbon cable.
Several 16-channel devices can be evaluated using the software.
The analog input signals from the strain gauges are amplified by 8 or 16 precision
measuring amplifiers GSV-1L to ± 5 volt and digitalized by the integratedA/D card with
USB interface.
A supplement for quarter bridges 350 ohm, and for half bridges 120, 350 or 1000 ohm is
included in the BSC8D and can be activated via solder bridges.
The benefit of the GSV-1L measuring amplifier used is the low-noise amplification and
automatic analog zero adjustment.
The zero adjustment is triggered via a switch or via software.
The zero point is stored internally and is available again after a voltage interruption.
Due to the automatic zero adjustment, the low-noise amplifier and the optimally adjusted
Bessel filter, high input amplifications can also be set for the A/D digital converter in order
to record the smallest signals.
The supply voltage is 12...24V DC and is supplied via a plug-in power supply provided.
