SOM-R
Spread oil meter/surface pressure-area isotherm
During the production of rolled steel, tin, or aluminum sheets, oils such as DOS, CSO, or ATBC are used as a coating medium to prevent sheets from rusting. Monitoring the amount of oil coated on the sheets is essential to ensure the production of high-quality metal sheets.
Using test metal sheets from the production line, our Automatic Spread Oil Meter SOM-R determines the oil amount by transferring the oil coated on the rolled metal test sheets onto a water surface and detecting the change of the surface film pressure.
Features
- Utilization of the Wilhelmy plate method to precisely detect the surface film pressure and to determine the oil volume in the range of μg on a test metal sheet
- Two independent temperature control systems to ensure reliable results and high repeatability even in difficult measuring environments
- Indication of the oil volume in mg/m2 on a LED display
- Easy to clean Teflon-coated trough with excellent corrosion resistance
- Easy to clean measuring probe (glass plate)
- Periodical calibration of the balancing system can easily be done by the user
Options
- Step down voltage transformer to convert foreign voltages to AC100V of the SOM-R
Applications
- Monitoring the amount of the oil coated on rolled steel, tin, or aluminum sheets
