Hardy Process Solutions

Electronic calibration of a weighing system without test weights. Hardy states it calibrates from one reference point, eliminates the need for full-scale test weights, and stores the calibration data in a chip inside the load cell so it cannot be lost.

Use it whenThis is the argument for Hardy on any vessel, silo, or tank you cannot practically hang certified weights on - which is most of them. Quantify it for the customer in crane time, contractor time and lost production, not in features. It also means a replacement load cell arrives already carrying its own calibration data. Hardy publishes a C2 load sensor certification lookup for verifying a sensor after the fact.

Diagnostics that let you troubleshoot the weighing system from the front of the instrument or through the PLC, displaying system weights, voltages and pass/fail results to isolate a fault to the instrument, the cabling, or the sensors.

Use it whenSell this to maintenance. The usual failure mode on a weighing system is nobody knows whether the problem is the cell, the cable, or the instrument, so somebody swaps parts. IT settles it at the panel and stops the parts-cannon.

WAVERSAVER filters the effect of surrounding vibration out of the weight signal so the reading is stable; WAVERSAVER+ is described as noise suppression.

Use it whenUse this as the answer whenever a customer says the scale is jumpy or will not settle. Mixers, conveyors, compressors and forklift traffic all put mechanical noise into a vessel, and that is what stops a fill from hitting target. Bring it up before the customer has to complain.

Check-weighing management, in a static version and a dynamic version, for product inspection by weight.

Use it whenSpecify the dynamic version when product is weighed in motion on a line, and the static version when it stops to be weighed. Hardy states its checkweight controllers are built to sit inside a fully integrated checkweighing system and give accurate, stable, fast weighing while products are in motion.

Real-time feed management for material feed control by weight and by rate.

Use it whenThis is the one for loss-in-weight and gain-in-weight feeding, and for continuous blending by rate - where the control target is pounds per minute, not a final total.

WEBSERVER gives remote access and setup; SMM is described as secure configuration.

Use it whenBring up WEBSERVER where a plant wants to configure or check an instrument without walking to it, and SMM where change control on instrument settings is an audit issue - regulated food and pharma sites in particular.

A weight controller with a dual-core processor, positioned for a wide variety of weight-based applications combining process control with weight data.

Use it whenUse it when the weighing instrument itself should run the batch or fill sequence, rather than reporting a weight to a PLC that does the logic. Good default where there is no PLC to plug into, or where the weighing sequence should stay self-contained.

The same controller class with a seven-inch touchscreen display.

Use it whenTake this over the HI6800 when an operator has to interact with it at the machine - select a recipe, watch a fill, acknowledge an alarm. If it lives in a closed panel, save the money.

A continuous material feed rate controller version, with five-point auto rate calibration.

Use it whenThis is the specific model for continuous feeding where the controlled variable is rate rather than a batch total - loss-in-weight feeders and continuous blending. The five-point auto rate calibration is what makes it hold rate across a range instead of only at one setpoint.

A DIN-rail single-channel unit, available as a weight processor with EtherNet/IP or PROFINET, or as a weight transmitter with 4-20 mA analog.

Use it whenUse it for one scale on a DIN rail inside an existing panel. Hardy positions the transmitter versions for level-by-weight and force measurement feeding a DCS, PLC/PAC or PC. Pick the analog version when you only have a spare 4-20 mA input, and the network version when you want the extra diagnostic data.

An EtherNet/IP-enabled weight processor with Rockwell integration, with multi-channel display and Modbus and Ethernet options.

Use it whenUse it on a Rockwell plant where the weight has to appear in the PLC cleanly and the integration work should already be done. Hardy is a Technology Partner in the Rockwell Automation PartnerNetwork, which is worth saying to a controls engineer who has been burned by generic gateways.

A modular system that delivers up to thirty channels over fieldbus networks.

Use it whenThis is the one for many scales at once - a tank farm, a silo array, a filling line with a scale per head. When a customer describes twenty weighing points and one network drop, stop quoting individual processors and quote this.

A modernized processor with faster update rates, dual Ethernet ports, a color touchscreen, and NTEP certification.

Use it whenTake this when the weight is used in trade or has to be legal for commerce - the NTEP certification is the deciding factor. The dual Ethernet ports also matter where a network topology needs daisy-chaining rather than a star. Hardy also lists it under product inspection alongside the HI6850.

A weigh scale module for Rockwell ControlLogix.

Use it whenUse it on a ControlLogix rack when the customer wants weighing inside the PLC program with no external box to power, wire, mount, or maintain. It removes a network node and a failure point.

High-performance single or dual-channel plug-in modules for Compact 5000 PLCs, with a 24-bit sigma-delta converter, described by Hardy as acting as a co-processor to the control system to speed up system performance.

Use it whenUse it on CompactLogix 5380 systems. The co-processor argument is the real one: the weighing math happens on the card, not in the PLC scan, so a fast fill does not compete with everything else the processor is doing. Take the dual-channel version where two scales sit near each other.

A weigh scale module for Point I/O.

Use it whenUse it where the scale is remote from the main rack and there is already a Point I/O drop nearby - it puts the weighing electronics out at the equipment instead of running long load cell cable back to the panel.

A weigh scale module for PointMax I/O, and currently the newest module Hardy is promoting on its home page.

Use it whenSame distributed-I/O logic as the HI1734-WS, for plants standardising on PointMax. Being the current model, this is the one to quote on new builds rather than extending an older platform.

Stainless steel hermetically sealed bending beam cells carrying the C2 calibration chip, listed in low and higher capacity versions (HIBBH06, HIHBB01).

Use it whenUse these for tanks, hoppers and platforms in wet or washdown areas - hermetic sealing is what keeps moisture out of the strain gauge, which is the usual reason a cell drifts and dies. Combined with C2 they replace themselves without a recalibration exercise.

Stainless steel single-point cells (HISP1, HISP6), plus HISP4 for hazardous areas.

Use it whenUse a single-point cell under a platform or bench scale where one cell has to carry the whole deck and stay accurate wherever the load sits on it. Specify the HISP4 when the area is classified.

S-beam cells for tension (HISTLB).

Use it whenUse these for suspended loads - a hanging hopper, a bag-filling frame, a crane or hoist. If the vessel hangs rather than sits, this is the geometry you want.

Complete compression mounting assemblies including the OneMount ADVANTAGE shear beam load point (HIONELP, with a separate low-capacity version), the ADVANTAGE rocker assembly for heavy capacities (HILPRC03), low-profile load point systems (HIHPLP), and compression weight module systems (HILPB).

Use it whenUse these under any vessel, silo, or tank that sits on legs. Pick by capacity and by headroom: the low-profile systems when there is not enough room under the vessel to lift it for a conventional mount, and the rocker assemblies at the heavy end. Getting the mount right is what stops thermal expansion, piping strain and side load from showing up as phantom weight.

Tension load point assemblies (HIHLPT) for mid-range suspended capacities.

Use it whenThe mounting counterpart to the S-beam cells - use it when a hopper or frame is hung rather than supported, and you want the whole assembly rather than sourcing rod ends and hardware yourself.

Mounts specified for dynamic weighing (HIRCDM).

Use it whenUse these where the vessel is agitated, mixed, or otherwise moving while it weighs. Pair them with WAVERSAVER - the mount handles the mechanics and the filter handles the signal.

A configurable bench scale with rugged construction and stainless steel tops, which Hardy says can be configured either with standard interfacing to a weight instrument or with a built-in direct connection to a PLC or PC.

Use it whenUse it when size and capacity need to be built to the job rather than picked from a catalog, in either a lab or a plant. The direct-to-PLC option is the one to raise with an integrator who does not want an extra instrument in the loop.

A bench scale series Hardy describes as the world's first IIoT-ready scale base, with a Hardy weight processor integrated into the base for direct EtherNet/IP network connection.

Use it whenUse it when the goal is fewer parts and fewer failure points - Hardy makes the point that it removes splice boxes and other components, which is where intermittent scale faults usually live. Best fit where the scale plugs straight into an EtherNet/IP network.

Three tiers of stainless steel bench scale, offered so a customer can pick capability against budget.

Use it whenUse these for standard industrial bench weighing. Work up the series as duty, environment and required configurability increase; Hardy's own framing is choosing the right product at a price that fits.

An easy-to-clean, low-profile stainless washdown bench scale with an optimised internal X design that Hardy says cuts cleaning time while keeping one of the lowest profiles available; the site also notes HIBSX is designed for washdown and for use in hazardous areas.

Use it whenUse it in wet food and beverage areas where sanitation crews are the real customer, and where a low deck height matters because operators lift onto it all shift. Confirm the hazardous-area rating per configuration.

A bench scale with an integrated seven-inch backlit display.

Use it whenTake this when the scale should be self-sufficient at the point of use with a large readable display, and no separate instrument is wanted on the wall.

Washdown industrial floor scales combining durability and precision with Hardy's weightless C2 calibration.

Use it whenUse these for pallets, drums, bins and bulk bags. C2 matters more here than anywhere - calibrating a floor scale conventionally means finding, moving and certifying a lot of test weight.
