YOUR STORE FOR LOAD CELLS, SCALE, WEIGHT INDICATORS.

Weight control from the silo to the bag.

Bulk material weighing for the whole line: weigh modules that turn silos and hoppers into inventory scales, batch controllers that run recipes by weight, fill controllers for automatic bagging, and digital transmitters that send live weight to your PLC or SCADA. Specified for plant builders, OEMs and integrators, and shipped from stock in Davie, FL.

A pneumatic bulk tanker unloading into a silo through a fill pipe. The silo stands on four legs, each on a weigh module; cables from the modules run to a junction box and a weight transmitter on the leg. The silo is shown cut away so the material level can be seen rising as the truck unloads, then falling as a screw conveyor draws material off to batching. Truck delivery weighed in as it unloads Transmitter sends the weight to your PLC Silo cut away level by weight Weigh modules under every leg To batching

    Bulk material weighing solutions across the plant

    From the receiving hopper to the bagger, we add weight control, automation and integration to the silos, hoppers and lines you already run. Pick a solution to see where it fits and what it includes.

    One supplier for every weigh point

    Every orange part on the drawing is something we supply: modules under the silo and hopper legs, load cells on the batch hopper and the bagger, the controllers that run them, and the transmitters in the panel. Pick a solution above, or tap a ring on the drawing.

    Inventory by weight

    Weigh modules under each leg turn a silo, hopper or tank into a live inventory scale. The reading is the weight of what is inside, independent of material density or angle of repose, so stock counts and reorders run on real numbers.

    What it takes
    A stainless batch indicator on a bench stand, its screen showing a batch with target, actual and deviation

    Recipe batching

    One controller runs a recipe across one or more weigh hoppers. It weighs each ingredient against its target, holds the batch when a weighment falls outside tolerance, and stores recipes by name, so every batch is made the same way by any operator.

    What it takes
    A stainless fill controller for automatic bagging, its screen showing the fill weight and target

    Automatic bagging

    A fill controller weighs every bag to a set target: fast coarse feed, a slow fine dribble near target, and in-flight compensation for material still falling when the gate closes. Open-mouth, valve and bulk bags fill to weight without an operator topping up.

    What it takes
    A DIN-rail digital weight transmitter with an EtherNet/IP port and screw terminals

    PLC and SCADA integration

    Digital weight transmitters turn each silo, hopper or bagger into a live signal in the panel. Single- and multi-channel models output analog or connect over RS-485 Modbus and industrial Ethernet, so weight goes straight into your control logic and inventory records.

    What it takes
    A replacement weigh module kit: four shear-beam weigh modules with cable and a junction box

    Retrofit and upgrades

    Replace the load cells, modules or indicator on an existing hopper, silo or tank without rebuilding the structure. Standard mV/V output and common mounting envelopes make most parts interchangeable, and we confirm the electrical and mechanical match before quoting.

    What it takes

    Batch and fill automation that runs the line

    A batch or fill controller handles every step of the weighment, so the line runs to weight instead of to an operator's judgment. Each scale can also hand its weight to your PLC or SCADA through a transmitter.

    Coarse and fine feed
    Fast bulk feed switches to a slow dribble near target, tightening the cutoff and reducing overrun.
    In-flight compensation
    The controller accounts for material still in free fall when the gate closes, and adjusts over consecutive cycles.
    Saved recipes
    Operators pick a recipe by name and the controller loads every target weight, tolerance and sequence step.
    Automatic tare
    Container weight, an empty conveyor or hopper pre-load is removed at the start of each cycle, with no operator input.
    Tolerance enforcement
    Any weighment outside the recipe window holds the batch, sounds an alarm and logs the deviation before the next cycle releases.
    PLC and SCADA handoff
    Digital transmitters send live weight to the host system as analog, RS-485 Modbus or industrial Ethernet.

    Questions buyers ask

    What batching or filling accuracy can we hit?

    It depends on material flow, feed design and how well the load-cell capacity matches the load. Coarse and fine feed with in-flight compensation holds a tight tolerance, and we sanity-check your application before we quote.

    Do weigh modules measure silo inventory accurately for any material?

    Weigh modules measure the weight of what is in the silo or hopper, so the reading does not depend on material density or angle of repose. Tell us the full silo weight and the number of legs and we spec the module kit.

    How does the weight get to our PLC or SCADA?

    Through a digital weight transmitter in the panel. Single- and multi-channel transmitters send live weight as an analog signal or over RS-485 Modbus or industrial Ethernet, so your control system reads every silo, hopper and bagger directly.

    Are your load cells and modules interchangeable with our existing equipment?

    Usually, yes. mV/V output and standard mounting envelopes are common across the industry. Send a nameplate photo or spec sheet and we confirm electrical and mechanical compatibility before quoting.

    Do you offer OEM or dealer pricing?

    Yes. Plant builders and authorized integrators get tiered pricing on controllers, modules and indicators. Send your business details and we route you to the dealer program.

    What are typical lead times?

    Stock ships same day from Davie, FL. Specialty configurations such as custom mounting or oversized capacity typically take 1 to 6 weeks. Exact dates are confirmed with the quote.
