Fujifilm Prescale can measure pressure and visualize the pressure range applied.
When pressure is applied, the microcapsules rupture and the color-forming material reacts with the color-developing material. Red patches appear on the film.
Structure
Single plate type: Color developing material is coated on a polyester base, with microencapsulated color material coated on top.
Two-plate type: One membrane is coated with microcapsule color material and the other membrane is coated with color developing material. Use two membranes facing each other with the coated sides facing each other.
| Two-sheet type | Single sheet type | |
|---|---|---|
| Accuracy | ±10% or less (when measured with a densitometer at 23°C, 65%RH) | |
| Recommended temperature | 20°C~35°C | |
| Recommended humidity | 35%RH~80%RH | |
Engine seal surface pressure measurement, flange surface pressure analysis, ground/tire contact surface pressure analysis, rolling contact pressure measurement, etc.
Pressure distribution and pressure measurement are significant issues when tightening engine cylinder gaskets. However, by inserting “Prescale” between the cylinder block, gasket and cylinder head, the measurement can be done simply by tightening. The great thing about “Prescale” is that its application to the performance test of “Cylinder head gasket for automobile engine” according to JIS D3150 standard has also been demonstrated.
The flange surface must be tightened firmly and with an appropriate amount of pressure to prevent oil leakage. When measuring with sensors, etc., it is difficult to measure the pressure distribution over the entire area. However, by inserting “Prescale” between the flanges, simply tighten. The pressure distribution can then be accurately read by attaching the “Prescale” into the reader.
Tires are an important part of the car that is necessary for safe and accurate “steering”, “turning” and “stopping”. By analyzing the ground contact surface where the tire contacts, the ground pressure can be distributed and analyzed easily and accurately without the need to route sensor cables, etc. This method only requires inserting “Prescale” between the ground contact surface (asphalt, etc.) and the tire. Then, attach “Prescale” to the reading device, if using the FPD-901 Series, the ground contact distribution can be obtained by visual observation and with numerical values.
In the past, the tension of rolled steel plates was determined based on a combination of past experience and intuition. However, errors such as part of the roll swelling often occurred, so there was no other way but to perform the cutting method and repeated testing until the appropriate tension was achieved. However, rolling steel plates together with “Prescale” allows precise rolling pressure measurement, allowing standardized tension adjustment and contributing to cost reduction.
We hope you find this information useful. As we can see, Fujifilm prescale applications are wide-ranging across the manufacturing industry, with many factors at play in each example of a machine installation. Due to this level of variation, there is rarely a “one size fits all” solution for your business’s condition monitoring needs. To that end, We at SEMIKI welcome the opportunity to talk to you about your pressure measurement requirements and would be happy to help you plan to handle your critical assets and improve your overall condition monitoring strategy.
