ZEMIC HM14H1-C3-30t-16B 30 Ton Column Load Cell (C3, IP68)
ZEMIC HM14H1-C3-30t-16B is a high-precision column-type compression load cell from the world-renowned manufacturer ZEMIC. This model is one of the most popular choices for truck scales, heavy-duty platform scales, hopper, silo, and tank weighing systems in Russia and CIS countries.
The load cell meets the international standard OIML R60, has accuracy class C3, and the highest protection rating IP68 (fully hermetic, withstands prolonged submersion in water).
Key Advantages
- Fully hermetic IP68 protection (welded stainless steel housing)
- Accuracy class C3 — 3000 verification intervals
- Nickel-plated alloy steel — excellent corrosion resistance
- Self-centering design with ball support
- Long shielded cable — 16 meters
- No semiconductor elements — increased reliability
- Complete mounting kit HY-14-146-W1 included
