STG1604-8 Eight Channel Strain Testing System

Performance characteristics:

STG1604-8 eight channel strain testing system is a high-quality data acquisition product based on USB interface. It supports real-time synchronous sampling of eight channel LEMO analog inputs, using A/D converters to achieve independent input for each channel, and the input range for each channel can be set through software. The working voltage of STG1604-8 is 9V-36V and requires an external power supply. At the same time, the data acquisition system is equipped with a strain signal conditioning module, which can provide 2.5V or 5V bridge voltage power supply for the strain sensor. The output signal is input to the input terminal of the collector after passing through the differential signal conditioning circuit and filtering circuit.

lThe power supply voltage of STG1604-8 is+9VDC~+36V_DC(Typical value+24V)_DC）.

lSTG1604-8 provides a constant voltage source for the bridge, with a voltage of 2.5V_DCOr 5V_DCOptional.

lSTG1604-8 is a differential input with strong resistance to common mode interference.
