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
The SOM-R combines automated precision with specialized engineering to ensure high-accuracy oil film measurement on metal sheets. Discover the core capabilities built into the system:
- ✔ High Precision Measurement:
- Quantifies minute oil film amounts on steel and aluminum surfaces using the highly sensitive Wilhelmy plate method
- ✔ Dual Independent Temperature Control:
- Features separate temperature regulation systems for both the sample plate and the trough to eliminate ambient thermal interference
- ✔ Automated Operating Sequence:
- Simplifies workflows by enabling programmatic control of spreading, barrier movement, stabilization, and direct data measurement.
- ✔ High Chemical Resistance:
- Using a Teflon-coated trough ensures long-term operational durability and simplifies routine cleaning.
- ✔ Streamlined Maintenance:
- The structurally independent design of the trough layout allows operators to clean it or swap components effortlessly.
- ✔ Integrated Control Unit:
- The comprehensive, built-in control amplifier reduces external clutter and simplifies configuration layouts in industrial settings.
Options
To ensure seamless integration into international manufacturing plants, we provide modular power adapters that match local electrical distribution systems.
- ✔ Step-Down Voltage Transformer:
- Available as an add-on accessory to safely convert international voltage line drops down to the system's required standard AC100V power supply
Applications
The SOM-R is specifically engineered for precision testing environments that require strict quality control over protective lubrication coatings.
- ✔ Metal Coating & Processing Lines:
- Ideal for monitoring thin, microgram-level quantitative amounts of synthetic rust-preventative lubricating oils (including DOS, CSO, and ATBC) coated directly onto steel sheets, rolled tinplate, and aluminum sheets
