FAQs
What is PSP?
Pressure-Sensitive Paint is a paint-like coating that, under certain conditions, fluoresces in a pattern that is indicative of the surface-pressure distribution.
What is TSP?
Temperature-Sensitive Paint is a paint-like coating that, under certain conditions, fluoresces in a pattern that is indicative of the surface-temperature distribution. More detail
Can PSP/TSP be used in liquids?
Theoretically, PSP based on oxygen quenching can be used in certain liquids. With current PSP technology the partial pressure of oxygen can be detected. Therefore, oxygen must be present at a density that is proportional to the phenomena (pressure) being measured. Also, optical access for excitation and interrogation must be available for proper operation of both PSP and TSP.
Will PSP detect a "force impact" with a memory?
No. PSP is capable of measuring relatively rapid changes of pressure; it is not capable of maintaining a pressure value for an extended period of time.
How long will a PSP/TSP coating last?
The lifetime of the pressure and temperature sensitivity varies among paint formulations and is dependent upon the environment. Some paints will maintain sufficient sensitivity in a darkened environment for weeks, while others will exhibit substantial losses in sensitivity within 1 hr after application in the presence of bright lights.

Is PSP/TSP difficult to apply?
PSP/TSP is applied using common spray-painting techniques.
