L6E Series – Aluminium Alloy Single Point Load Cell IP65 (30 kg – 500 kg)

L6E adalah load cell single point (parallel beam) aluminium alloy dengan pelapisan colourless anodized, dirancang untuk timbangan retail, laboratorium, dan industri ringan yang memerlukan akurasi tinggi, bobot ringan, serta proteksi IP65 (tahan debu & cipratan air ringan). Load cell ini sangat populer untuk pricing scale (timbangan harga di pasar/supermarket), bench scale (timbangan meja), platform scale sedang (400 × 400 mm), counting scale (penghitung jumlah barang), dan berbagai electronic weighing devices yang menggunakan platform ukuran kompak hingga sedang.

Desain parallel beam-nya memberikan akurasi tinggi dengan corner effect rendah (eccentric loading error minim), deflection terkendali, dan kestabilan suhu baik, sehingga tetap presisi meski beban tidak tepat di tengah platform. Aluminium alloy anodized membuatnya ringan (weight rendah ~0.5–1 kg tergantung kapasitas), tahan korosi ringan, dan sangat ekonomis dibanding stainless steel – ideal untuk aplikasi indoor/retail di mana IP68 tidak dibutuhkan. Opsi C5 memberikan resolusi sangat tinggi (hingga 5000 divisi) untuk timbangan presisi ekstra.
