The main difference between SensorPROM and SensorFlash lies in their purpose and functionality:

  1. SensorPROM (Programmable Read-Only Memory) stores factory-set calibration data and unique sensor information. It is read-only, meaning its data is typically not altered during the sensor’s operation. This ensures consistent and accurate sensor performance without requiring recalibration.
  2. SensorFlash refers to re-writable memory that can store dynamic data such as configuration settings, usage logs, or firmware updates. It allows for changes and updates, making it more flexible for field adjustments and reprogramming.
  • SensorPROM: Stores permanent calibration data, not typically changeable.
  • SensorFlash: Allows re-writable storage for settings and updates.
