Waterproof Load Cells for Reliable Weighing
waterproof load cell
In many weighing applications, moisture is the main enemy. A standard load cell exposed to water or high humidity can drift or fail outright. Kingmach’s waterproof load cells are built to handle these conditions. We use sealing methods that block water ingress at the cable entry, the strain gauge area, and the housing—so the sensor keeps working even under regular washdowns or in damp environments. These are not laboratory curiosities; they are tools for everyday industrial weighing where liquids are present, from mixing tanks to outdoor silos.
Technical Detail
Configured around process stability, mold life, and long-term uptime.
Kingmach Measurement & Monitoring Technology Co., Ltd. supplies waterproof load cells that cover a practical range of capacities and shapes—beam, single point, S-type, and canister. The common thread is protection against moisture. Most units meet IP67 or IP68, meaning they withstand temporary submersion or high-pressure jets. The gauge area is sealed with potting and O-rings, while the cable uses a compression gland. The body is often stainless steel, resisting both water and many cleaning agents. That matters in food processing, where equipment gets hosed down daily. It matters in chemical batching, where spills are routine. It also matters outdoors: platform scales, hopper weighing, or structural load monitoring exposed to rain. Without waterproofing, a sensor’s insulation resistance drops, and the signal becomes unreliable. Kingmach’s designs maintain stable bridge resistance, so your readings stay credible. We are a mid-range supplier with global reach and a focus on geotechnical and weighing instruments. If a standard product doesn’t fit your project, we can customize capacities, threads, or cable lengths. Our support team helps with installation questions and long-term service. This makes waterproof load cells a sensible choice for any scale builder or integrator who needs weighing components that outlast harsh cleaning schedules or weather.

FAQ
Common technical questions
What IP rating do Kingmach waterproof load cells typically have?
Most are rated IP67 or IP68. IP67 means temporary immersion in 1 meter of water for 30 minutes, while IP68 means continuous immersion under conditions specified by the manufacturer. The exact rating depends on the model, but both are suitable for wet industrial environments.
How do you prevent water from entering the load cell over time?
We use multiple barriers: a welded or O-ring sealed outer body, glass-to-metal seal at the strain gauge, and a compression fitting at the cable exit. The gauge area is potted with an insulating compound. This multiple-line defense keeps moisture away from the sensitive elements even with repeated washing.
Can these load cells be used in food processing where washdown includes chemicals?
Yes, for most food-grade applications the stainless steel body and sealed design hold up against common detergents and sanitizers. Avoid concentrated acids or strong solvents that can attack seals. For extreme chemical exposure, we can advise on material options.
What should I check during installation to maintain the waterproof rating?
Ensure the mounting surface is clean and the load cell is not twisted when tightening bolts. Do not kink the cable, and keep the cable exit pointing downward so water runs off. If using connectors, confirm they are fully mated and any caps are in place. Avoid dragging the load cell by its cable, as that can compromise the gland.
How does Kingmach support after-sales for waterproof load cells?
We offer technical guidance on selection, installation, and troubleshooting. Our distributors carry spare parts and can arrange recalibration. If a sensor fails due to a manufacturing defect within warranty, we replace it. For water-damaged units outside warranty, we can inspect and advise on repair feasibility.
