TraceTek Sensors
The special thing about the TraceTek sensor used in the oil context -TT5000- is that the detection itself takes place on the basis of a chemical reaction. The sensor cable contains a doped polymer which, when exposed to liquid hydrocarbons, ie all oil-based products, triggers a chemical reaction. This reaction causes, among other things, that the polymer starts to swell (expand). This expansion then develops a pressure build-up at the physical point in the cable the exposure occurs.
