Column Load Cells

Column load cells are designed for heavy supported loads in weighbridges, silos, tanks and large process structures. Their compact footprint allows substantial force to pass vertically through the sensor.

The Laumas range includes analogue CO, COK and COL models alongside the COD digital column load cell. Select by capacity, dimensions, mounting arrangement, environmental protection and system interface.

Column load cells for high-capacity structures

Column load cells provide a compact weighing point for high-capacity structures. They are commonly installed beneath weighbridges, silos and large vessels where the force acts vertically through the sensor.

The surrounding structure and mounting hardware must keep the load centred while accommodating normal movement. Where several analogue sensors support one structure, a junction box can combine their signals before connection to a weight indicator or weight transmitter.

The COD model uses a digital interface and should be matched to compatible control equipment; compare it with the wider digital load cell range.

Column load cell selection

Column load cells carry high compressive forces through a compact cylindrical body. They are widely used beneath weighbridges, silos, tanks and other structures with substantial point loads.

Calculate the maximum load at each support using the structure’s dead weight and contents, with allowance for uneven distribution and movement. Correct alignment and suitable mounting hardware are essential because side loading can affect measurement and damage the sensor.

Analogue and digital column models require different electronics and cabling. Check the output or protocol, wiring, power and controller compatibility before specifying a replacement.

High-capacity load measurement

The compact column format suits high-capacity supports where force can be applied vertically through the centre of the sensor.

System compatibility

Analogue models must match the excitation and input of the weighing electronics. Digital models require the correct protocol, power and controller configuration.

Mechanical installation

Mounting hardware, restraints, alignment, cable protection and access for inspection should be considered as part of the structural design.

Typical applications

Column designs are intended for heavy structures where each weighing point supports a substantial compressive load.

Weighbridges

Weighbridges use several column sensors beneath the deck to measure vehicle loads across the supporting structure.

Silos and tanks

Silos and tanks can be weighed for inventory, batching and process control while remaining installed in the production plant.

Hoppers and material handling

High-capacity hoppers and material-handling structures use the measured load to monitor filling, discharge and stock levels.

Digital column systems

Digital column models can provide individual sensor data and diagnostics when used with compatible weighing controllers and network infrastructure.

How to choose column load cells

Calculate the load at each support first, then confirm dimensions, mounting, environmental protection and electrical or digital compatibility.

Capacity and load distribution

Include the structure, maximum contents and any unequal distribution. Allow for dynamic loading and overload conditions expected in service.

Mounting and alignment

The load should pass vertically through the sensor. Check loading surfaces, mounting assemblies, restraints and freedom for normal structural movement.

Operating environment

Choose protection and construction suited to water, corrosion, temperature, traffic and the cleaning conditions at the site.

Electronics compatibility

For analogue models, match excitation, output and wiring. For digital models, verify protocol, power, addressing, cabling and controller compatibility.

Column load cell FAQs

These checks help determine whether a column model will suit the structure and the existing weighing electronics.

What are column load cells used for?

They are used beneath weighbridges, silos, tanks, hoppers and other high-capacity supported structures.

How do I choose the correct capacity?

Calculate the maximum load at each support using dead weight and contents, with an allowance for uneven loading and movement.

Can I replace an existing column load cell with another model?

No. Dimensions, loading surfaces, capacity, output or protocol, wiring and mounting must all be compatible.

How do column load cells connect to a weighing system?

Analogue models normally connect through a junction box to an indicator or transmitter. Digital models connect to compatible controllers using their specified interface.
