HM8 adalah load cell shear beam (tipe geser) heavy-duty berbahan nickel plated alloy steel, dirancang khusus untuk timbangan berat industri ekstrem seperti truck scale (weighbridge), track scale (timbangan rel), hopper scale besar, silo/tank weighing, dan sistem weighing berat lainnya yang memerlukan proteksi IP68 hermetically sealed (tahan perendaman air sementara, debu total, korosi tinggi) serta ketahanan terhadap beban samping, getaran kendaraan berat, dan lingkungan outdoor keras seperti pertambangan, pabrik semen, pupuk, atau area dengan risiko banjir ringan.
Desain shear beam-nya memberikan kekakuan radial tinggi terhadap gaya lateral & puntir (lebih unggul dari single point atau column pada beban dinamis), deflection rendah, serta kestabilan akurasi tinggi meski ada beban tidak simetris atau getaran dari truk/kereta lewat. Nickel plating memberikan proteksi korosi yang baik dengan biaya lebih ekonomis dibanding full stainless steel, sementara IP68 memastikan tahan cuci bertekanan tinggi atau kondisi basah ekstrem. Cocok untuk instalasi di pondasi beton atau struktur baja dengan mounting foot/mount self-aligning untuk centering otomatis & lift-off protection.
