Abstract
Aspects of monitoring using harsh environment sensing devices and systems are described. Multiple parameters are detected using the sensing devices immersed in a harsh environment such as a caustic solution. The parameters detected using the harsh environment sensing devices and systems include pressure, depth, density, temperature, or any combination thereof.
