Load cell families and selection parameters
Select mechanical geometry according to load application: cantilever shear beams, dual shear assemblies, tension S-cells or single-point bench sensors.
H8C shear beam load cells
H8C is a nickel-plated alloy steel shear beam load cell designed for platform scales, hoppers and batching systems. The series spans capacities from 100 kg to 10 t with OIML R60 C3 accuracy class and a standard output of 3.0 mV/V.
When replacing a damaged load cell, verify the mounting thread, foot height and cable wiring against the installed schedule. Confirm whether the installation uses a 4-wire or 6-wire circuit with sense feedback.
For washdown or corrosive environments, compare requirements against the stainless steel hermetic BM8D variant. Ensure the summing junction box and indicator input are aligned with the sensor impedance.
HM9B dual shear beam load cells for truck scales
HM9B dual shear beam load cells are engineered for heavy-duty truck scales, weighbridges and track scales. The double-ended shear design with spherical seating absorbs structural deflections and thermal expansion of the weighing platform.
Available capacities include 10 t, 20 t, 25 t, 30 t, 40 t and 50 t with IP68 hermetic sealing and 2.0 mV/V sensitivity. For maintenance replacement, record the complete part number including load rating and cable length suffix.
Check bridge resistance and insulation integrity across all platform cells, as pit moisture often affects zero stability. Re-cornering and calibration must follow after installation.
H3 S-type tension and compression load cells
H3 S-type load cells measure tension and compression forces in suspended hoppers, batching vessels, crane scales and material testing rigs. The alloy steel nickel-plated body covers capacities from 25 kg up to 30 t with IP67 protection and high zero-point stability.
Axial threaded holes allow direct fitting of rod-end swivel bearings to eliminate bending moments. When ordering replacement units, confirm thread type, nominal capacity and overload margins. For food, chemical or aggressive washdown processes, select the stainless steel B3G variant.
Check tare weight and shock factor when sizing suspended hopper weighing systems.
L6D single point load cells for bench scales
L6D is an anodized aluminum single-point load cell with integrated corner-load compensation for retail, bench and counting scales. The parallelogram spring element ensures accurate weight readings regardless of where the load is placed on the platform.
Nominal capacities range from 3 kg to 50 kg for platform dimensions up to 250x350 mm. Do not confuse L6D with variants like L6D8 or L6D15, which feature different bolt-hole spacing and body heights. Verify mechanical dimensions and mounting patterns before purchasing replacements.
Tighten platform screws using the recommended torque to avoid mechanical pre-stress.
L6E single point load cells for medium platforms
L6E single-point load cells are built for packaging stations, medium platform scales, checkweighers and conveyor batching units. Designed for platform sizes up to 400x400 mm, capacities span 50 kg to 300 kg with C3 accuracy and 6-wire sense circuit connection.
The sense wires monitor excitation voltage at the bridge to prevent measurement errors caused by long cable runs. In conveyor weighing, inspect cable routing against mechanical vibration and abrasion.
Distinct series such as L6E3 and L6G offer alternative dimensions and capacities up to 600 kg; compare physical drawings prior to procurement.
BM14G is a hermetically sealed stainless steel rocker-column compression load cell for heavy-duty vehicle scales, silos and rail weighbridges. Laser-welded construction provides dual IP68 and IP69K ingress protection against high-pressure washdown and submersion.
Capacities range from 10 t to 100 t with integrated surge protection against lightning strikes. The self-centering rocker design resists rotation during dynamic vehicle passage. When servicing, inspect the upper and lower hardened load cups for pitting or wear, which cause load misalignment.
Ensure the heavy copper bypass strap connects platform to ground.
BM11 stainless steel bending beam load cells
BM11 is a precision stainless steel bending beam load cell featuring a laser-welded metallic bellows for demanding process environments. Designed for conveyor scales, loss-in-weight feeders, packaging machinery and small vessel weighing, capacities range from 5 kg to 500 kg with IP68 protection.
The bellows isolates the strain gauge bridge from moisture, chemicals and fine dust while maintaining high compliance along the measuring axis. During replacement, avoid any mechanical contact or torque on the bellows body.
Load must be applied strictly through the designated mounting hole in the arrow direction.
Junction boxes, signal transmitters and mounting kits
Zemic accessories complete the weighing chain from primary sensors to automation systems. The product scope includes JB series 4, 6 and 8-channel summing junction boxes with multi-turn trimming potentiometers for platform corner tuning.
DIN-rail signal transmitters like EM06 and EM08 convert bridge signals into 4-20 mA, 0-10 V or Modbus RTU protocols for direct PLC connection. Mounting accessories include shock-absorbing elastomer pads, rocker assemblies and tie-bar kits to prevent vessel tip-over from wind or agitation.
Always check junction box seal condition when troubleshooting zero drift.
Wiring diagrams and cable specifications
Correct electrical wiring is essential for stable, drift-free measurement in industrial weighing systems. Zemic load cells utilize standardized 4-wire and 6-wire shielded cables with dedicated excitation, signal and sense conductors.
In a 6-wire circuit, sense lines provide closed-loop voltage feedback to the transmitter, compensating for temperature-induced resistance changes across extended cable runs.
Never splice or shorten 4-wire cables without re-calibrating the entire scale, as cable resistance forms part of the bridge calibration. Terminate cable shields at a single star ground point to prevent ground loops and electromagnetic noise.
Troubleshooting and bridge diagnostics
When a weighing system experiences zero drift, non-linearity or error codes, systematic electrical diagnostics will isolate the malfunctioning load cell. Measure input and output bridge resistances with a calibrated digital multimeter and compare them against factory datasheet tolerances.
Test insulation resistance between all conductors and the metallic sensor body using a 50 V insulation tester; a reading below 5000 MOhms indicates moisture ingress or hermetic seal failure. Check the unloaded zero balance signal in millivolts.
A permanent zero shift beyond 1% of rated output confirms mechanical plastic deformation.
Selection and replacement procedure
When sourcing replacement load cells for production machinery or batching systems, a structured procedure ensures minimal equipment downtime. Capture clear photographs of the rating plate, mechanical mounting arrangement and cable termination.
Document rated capacity, mV/V sensitivity, bridge impedance and cable length. Identify the receiving instrument or PLC weighing module.
Where an older model is discontinued, our engineers determine suitable drop-in replacements within the current Zemic catalog matching physical dimensions and load ratings, confirming all parameters prior to delivery.
Compile a schedule of weighing points: tanks, silos, truck scales or conveyor belts. State gross and tare capacities, number of supporting points, wind loading and vibration levels. Attach mounting envelope sketches, electrical excitation voltage and PLC signal requirements. Differentiate operational units from reserve spares.
Procurement conditions and boundaries
Specify sensor part numbers when ordering summing boxes, elastomer mounts or cables. Pricing, lead time, documentation and availability are confirmed for the exact part number. We do not claim authorized distributor status; component compatibility is evaluated from technical datasheets.
