  • A fast-response thin film thermocouple to measure

    2005-11-1 · “Fast” response is the time period during which the sensor accumulates heat from the laser pulse and has at least one oscillation that corresponds to the second order dynamic system. The incident laser light is absorbed at the surface of the thin film, within the optical skin depth that is typically tens of nanometers thick . The graphite film is therefore hotter than the metal substrate and then cools as it …

  • PG105 vs. Thermocouple Gauges - hanmisci.com

    2018-5-18 · The response time is very fast (milliseconds in most cases) because components do not have to change temperature as pressure changes. Response time to a pressure step-function is pressure dependent, but it is roughly about an order of magnitude faster than in TC gauges. Fast response time makes the PG105 convection gauge ideally suited for ...
