Sub-cooled water detection in silicon dew point …

The dew point sensor structure shown in Fig. 4, Fig. 5 was tested in the hygrometer presented in Fig. 1. Due to good light reflectivity, the structure could work as an optical mirror in a classical hygrometer with optical dew detection. The dew point temperature was measured with an eedded thermometer.

Detection of bubble and dew point using optical thin …

Specifically, in dew-point detection, any liquid forming (from an otherwise gaseous mixture) forms preferentially at the bottom of the PVT cell, and is subsequently detected by the bottom optical fiber sensor. Both types of phase transitions (dew-point and bubble-point) can exhibit temporary thin films on the sensor surface.

Moisture Detection - measure the Drying Process

The goal of moisture detection in the water damage restoration industry is to identify and assess abnormally wet loions of buildings, structures and their materials so that the drying process can be measured, documented and carried out effectively and in an economical and efficient manner.

Oxygen sensor - Wikipedia

2019-5-4 · The Clark-type electrode is the most used oxygen sensor for measuring oxygen dissolved in a liquid. The basic principle is that there is a hode and an anode submersed in an electrolyte. Oxygen enters the sensor through a permeable merane by diffusion and is reduced at the hode, creating a measurable electric current.
