G3001 Differential Amplifier & Excitation Module
|The G3001 is a simple signal conditioner/amplifier with DC Excitation used for
interfacing all bridge type sensors including: Straine Gage, Pressure sensors,
Thermocouples, Accelerometers, Photo Diodes, Piezo sensors etc.
The module contains a low-noise instrumentation amplifier, Gain and DC Offset sections and a Low Pass Filter. The bridge excitation is symmetrical and is capable of driving most bridge type transducers.
The module has internal bridge completion resistors and a shield driver for protecting the inputs from common mode noises. The unit features a high stability and low noise Excitation unit for driving the sensors.
This module can be used as a Strain Gage Amplifier for Load Cells, RTD or Load and Force measurement with Strain gage bridges or other bridge based piezo-resistive transducers (as pressure sensors). It can also be interfaces to most Temperature transducers, Piezo Sensors, Photo sensitive devices and most sensors having a voltage output. It can also be used as a Strain Gage monitoring system with many channels (combining few mainframes together). Due to it's low noise and high gain, it is an ideal solution for a strain gage force balance with op to 6 channels in one mainframe.
The amplifier can be operated by batteries and it's output signal can be transferred to the data acquisition system via the AFL-500 Analog Fiber optic Link for complete isolation of the system:
