Engineering Selection Guide (For System Integrators)

During industrial project implementation, engineering teams usually need to select suitable pressure sensor core components based on the system architecture. The following are the key technical parameters for WPAH01 / WPAH02:

Engineering Selection Suggestions:
Pressure Range Matching: Select the appropriate range based on the system working pressure and safety margin to avoid long-term operation near full scale.
Temperature Environment Evaluation: In high-temperature or outdoor equipment, design signal conditioning circuits in conjunction with the sensor's temperature adaptability of -40℃ to 125℃.
Output Signal Design: Since the sensor output is a mV/V ratiometric signal, engineering designs usually require pairing with:
* Instrument Amplifiers
* Signal Conditioning Modules
* ADC Data Acquisition Modules
To meet the input requirements of the control system.
