To evaluate how to procede with designing a particular solution to a problem we will need to establish some characteristics of the problem. Some of which are listed below:
- Temperature, ambient and variations.
- Gas environment
- Ambient humidity / water levels / IP requirement.
- Condensing atmosphere?
- Airborne dirt and dust.
- Ambient EMC levels. EMC emissions.
- Ambient radiation levels. Radiation hardened solutions?
- Acid / chemical environment.
- Vibration and vibration withstand ability requirement.
- Shock and shock withstand ability requirement.
- Pressure.
- Supply voltage & stability.
- The target material or object to be detected, measured, or sensed,
- The range of the target from the sensing elements.
- The characteristics of the target, which are to be detected or measured.
- Any materials required to be detected through or around.
- Any mechanical, installation or housing requirements.
- Integration with systems or actuators?
