3LW Pressure Measurement Film (LLLW) | 0.2-0.6MPa Ultra-Low Pressure Film

3LW Pressure Measurement Film (LLLW) SaiYon 3LW pressure measurement film, also referred to as LLLW pressure film, is intended for 0.2-0.6MPa ultra-low pressure testing. It is used to visualize pressure distribution, assess contact conditions, and support low-pressure testing tasks where visible color response is required. Product Information Model: 3LW (Ultra-Low Pressure Type, also known as LLLW)Sheet Type: Two-sheet structurePressure Range: 0.2–0.6 MPaShelf Life: 2 years Function:This film is used to visualize pressure distribution through color development.The color density corresponds to the applied pressure level, allowing pressure values to be evaluated using standard density reference curves. Features (1) Enables clear and intuitive evaluation of pressure distribution and contact uniformity.(2) Color density varies with applied pressure, allowing pressure levels to be interpreted using standard density charts.(3) Provides fast measurement with clear and easily interpretable results after pressure application. Product structure and working principle Stick the coating surface of L sheet together with the coating surface of K sheet. After applying pressure, the microcapsules carrying the color substance on the L plate ruptured, and the color substance reacted chemically with the corresponding K plate chromogenic agent, presenting a red color. The degree of microcapsule rupture is determined by the amount of pressure applied. The higher the pressure, the more microcapsules are damaged, and the higher the color density. On the contrary, the lower the hair color density. Standard Pressurization Conditions Pressure Distribution and Pressure Value Measurement Methods Pressure Distribution Using Pressure Test FilmBased on the changes in pressure, the red density of the film changes. The deeper the red color, the higher the pressure; the lighter the red color, the lower the pressure. When observing, place the colored K-film with the glossy PET side facing up on a white piece of paper in a well-lit area. Using Pressure Test Film with Standard Pressure...
