Smart Pressure Transmitter Reference Design

The main IC of the design is ADUC7061(core ARM7TDMI),which includes internal 24 bit ADC buffer & PGA(programmable gain amplifier). The module converts signal-in(EPCOS piezoresistive silicon pressure sensor) to 4 - 20 mA DC current. For high precision, there is internal linearizing calibration algorithm including temperature compensating in the MCU program. This platform uses RS232 for com interface, a PC software has been designed for debugging and setting of the parameters.(Users can use other interface, RS485 or Hart etc.)
