Product Information

Every silo eventually asks the same question: how much is actually in there? Level sensors answer with an estimate based on the assumption that your material sits at a consistent bulk density. That assumption breaks down fast with hygroscopic powders, variable-density aggregates, or anything that compacts, bridges, or cakes, which describes a large share of what gets stored in KSA and GCC silos, from cement and gypsum to grain, resin pellets, and chemical powders.

A silo weighing scale removes the guesswork. Compression load cells sit under the silo’s support legs or skirt, typically three or four per structure, and measure the true combined mass of the vessel and its contents, continuously. That reading goes straight to a weighing terminal and from there into your SCADA, DCS, or ERP system, giving your operations and procurement teams a number they can actually act on: reorder before you run dry, catch overfills before they become a spill or a safety incident, and settle supplier delivery disputes with a timestamped, calibrated weight instead of an argument.

Global Scales & Systems, as your industrial weighing partner for Saudi Arabia and the UAE, specifies, installs, and calibrates these systems locally, with SASO-aligned documentation and NMI-traceable calibration built into the process from day one.

Description

The Silo Weighing Scale Solution is an engineered weighing chain, not a single component. It combines heavy-capacity compression load cells (canister, ring, or POWERCELL PDX digital cells), a weigh module or mounting assembly that converts your silo’s structural supports into calibrated load points, and an advanced weighing terminal that turns raw load cell signal into a number your control system can use.

The load cells are hermetically sealed and rated up to IP69K, so washdown, dust ingress, and coastal humidity are non-issues. Where the digital POWERCELL PDX cells are specified, each cell carries its own onboard microprocessor, continuously correcting for temperature drift, non-linearity, hysteresis, and sensor creep, and reporting its own health back to the terminal. That means a failing cell shows up as a diagnostic alert on the terminal screen, not as an unexplained inventory discrepancy three weeks later.

For hazardous-area silos, oil and gas, petrochemical, and grain-dust environments among them, the load cells and terminal are available in ATEX, IECEx, and FM-approved variants, so the system can be specified correctly against your site’s zone classification from the outset rather than retrofitted after a rejected shipment.

Installation, calibration (including CalFree weightless calibration, which removes the need for test weights or confined-space entry), and ongoing accredited calibration services are delivered by GSS engineers on the ground in KSA and the UAE.

Product Parameters

Product Features

• Real mass, not an estimate. Weight-based measurement is immune to the density and packing variability that throws off level sensors, particularly relevant for hygroscopic powders and materials affected by Gulf humidity swings.
• No junction boxes to fail. POWERCELL PDX digital cells network directly to the terminal, eliminating the field-wired junction boxes that are a common point of failure and downtime in analog systems.
• Self-diagnosing load cells. Each digital cell reports its own condition (overload, zero drift, foundation issues) to the terminal, so problems surface as an alert, not as a mystery inventory gap.
• Calibrate without test weights. CalFree and RapidCal methods calibrate the scale without hauling certified test weights up to a silo or taking the vessel out of service, cutting calibration downtime and confined-space risk.
• Built for hazardous zones. ATEX and IECEx-certified components are available for oil, gas, petrochemical, and grain-dust classified areas, specified correctly against your zone study rather than bolted on afterward.
• Talks to your existing systems. Native EtherNet/IP, PROFIBUS, ProfiNet, and Modbus TCP connectivity means the weight reading lands directly in your SCADA, DCS, or ERP, no manual logging required.
• Washdown and corrosion resistant. Hermetically sealed, laser-welded construction rated to IP69K stands up to washdown, coastal humidity, and dust without performance drift.
• Lightning protection built in. StrikeShield technology on POWERCELL PDX cells is engineered specifically for exposed outdoor installations, relevant for silos standing in open yards across the Eastern Province.
• Locally certified, locally supported. GSS installs and calibrates every Mettler Toledo system in-Kingdom, with SASO-aligned documentation and NMI-traceable calibration certificates, so your compliance file is audit-ready from commissioning.
