Comparison GSV-8 with GSV-1A8USB
The two 8-channel measuring systems differ in the following points:
Housing: GSV-8 is optionally available in the IP67 housing with screw terminals, or in the aluminum profile housing with plug connectors;
Flexibility: The inputs of the GSV-8 are configurable for strain gauges, voltage, temperature; The inputs of the GSV-1A8USB are only for strain gauges.
Interfaces: In addition to the USB interface, optional fieldbuses CANbus or EtherCat are also available for the GSV-8.
Analog output: The analog outputs of the GSV-8 are configurable with regard to type 4 ... 20mA or + -10V. The offset of the analog outputs, the filter frequencies and the gain factors can be individually configured. The GSV-1A8USB always has a fixed assignment between input sensitivity (± 2mV / V) and analog output (± 5V).
Configuration: The configuration for the individual channels is stored in the GSV-8 in the device itself. On the GSV-1A8USB the configuration is stored on the hard disk of the connected PC.
Data acquisition: The GSV-8 uses state-of-the-art A / D conversion of analog devices. The 8 channels are recorded simultaneously with 8x48kS / s. The GSV-1A8USB uses an analogue measuring card with 250kS / s from National Instruments (USB6210).
The resolution of the measuring amplifier GSV-8 is higher than the resolution of the GSV-1A8USB:
