Function and Working Principle
The F9342AL CPU Assembly receives measurement data from the pressure sensing element and performs digital signal processing.
Its primary functions include:
- Processing raw sensor signals
- Applying temperature and linearity compensation
- Calculating the final pressure value
- Generating the standard transmitter output signal
- Managing transmitter diagnostics and communication
The processed measurement is then transmitted through the pressure transmitter’s analog or digital communication interface.
Operating Sequence
- Pressure sensor detects process pressure.
- Sensor signal is transmitted to the CPU assembly.
- The CPU performs signal amplification and digital processing.
- Compensation algorithms improve measurement accuracy.
- The processed value is converted into the transmitter output signal.
- Diagnostic and communication functions are executed.
