HM9B adalah load cell dual shear beam (geser ganda) heavy-duty premium berbahan nickel plated alloy steel welded, dirancang khusus untuk timbangan berat ekstrem seperti truck scale (weighbridge truk), track scale (timbangan rel kereta api), hopper scale besar, silo/tank weighing kapasitas tinggi, dan sistem weighing industri berat di lingkungan outdoor keras, pertambangan, pabrik semen/batu bara, pupuk, atau area dengan risiko korosi tinggi, minyak, air, gas korosif, serta beban dinamis dari kendaraan berat.
Desain dual shear beam-nya (dua zona geser paralel) memberikan kekakuan radial & lateral sangat tinggi, tahan gaya samping, momen puntir, dan getaran ekstrem (misal truk masuk/keluar atau material silo mengalir deras), deflection minimal, serta kestabilan akurasi jangka panjang. Hermetically sealed IP68 (welded steel proof) membuatnya tahan perendaman air sementara, debu total, cipratan minyak, dan gas korosif – cocok untuk instalasi outdoor tanpa perlindungan tambahan. Nickel plating memberikan proteksi korosi yang baik dengan biaya lebih ekonomis dibanding full stainless steel pada kapasitas super besar. Opsi SC (current calibrated) meningkatkan reliabilitas untuk aplikasi legal/metrologi kritis.
