CFSensor GZP6895A500KPP50H Differential Pressure Sensor, 0-500 kPa Range, 5V Analog Output, ROHS

This sensor provides a ratiometric analog voltage output, typically 0-5V, directly proportional to the applied differential pressure across its 0-500 kPa range. This output can be connected directly to a microcontroller's ADC pin or a PLC analog input module for measurement.

The sensor operates on a single 5V DC supply. Ensure your power source is stable and free from significant noise, as voltage ripple can affect the accuracy of the analog output signal. The current consumption is typically low, making it suitable for embedded systems.

Connect the sensor's VCC and GND pins to the Arduino's 5V and GND. Connect the sensor's analog output pin to one of the Arduino's analog input pins (e.g., A0). In your code, use the analogRead() function to get the raw ADC value and map it to the pressure range using the sensor's transfer function from its datasheet.

As a differential sensor with a range starting at 0 kPa, it measures the pressure difference between its two ports. A positive reading indicates higher pressure on the 'high' side port. It does not inherently measure negative gauge pressure, but the differential can be positive or negative relative to the port designation.

The specified accuracy is ±2% of full scale (500 kPa). Factors affecting real-world accuracy include power supply stability, temperature variations, mechanical mounting stress, and the quality of the signal conditioning/ADC in your readout system. For best results, operate within the specified temperature range and consider calibration for critical applications.
