How to tell if my sensor's sensitivity is suited to my application?
Question: How can I see if my sensor's sensitivity is suitable for my application?
Answer: Here are suggested steps:
- Open up a Real Time Window in your Tekscan software.
- Next, open up the Pressure Legend.
- Set the upper Pressure Legend field to: 255
- Set the lower Pressure Legend field to: 0
- Ensure that the units of the Pressure Legend are set to "Raw". (Right-click on Legend to select "Units".)
- Place the load on the Sensor. Make sure the load is compressive and within the Sensor's active boundary.
- Load the Sensor with the application's material interface, temperature, pressure, and for the desired time.
- You can click on the red Record button in the ToolBar to begin recording.
- View the recording (that is, the .fsx playback window) and ensure that the colors are not predominantly pink or blue.
- At the final application pressure, you ideally want to see a mix of colors (three quarters of the way up the scale from "0").
- It is best to have a mix of blues, yellows, orange, green, red and maybe a small amount of pink.
- If you see mostly blue, then the Sensor / Sensor Setting is too "cold" -- you will want a "hotter" sensor or a more sensitive gain setting.
- If you see mostly pink (older software versions use red for saturated areas), then the Sensor is too "hot" -- you will want a "colder" Sensor or a less sensitive gain setting.
