The part that does the weighing, for whatever weigher you have
Any make
Cells for the weighers we already maintain, and for the ones we have never seen.
50kg to 2500kg
Every common capacity, in metric and imperial ratings.
Certificate with every cell
Rated output, zero balance and resistances, on paper.
What we supply
Which cell a weigher takes is decided by how its weigh frame is built, so the range covers every mounting style you meet on a conveyor rather than one favourite type.
Types
- S type tension cells, for frames that hang the weigh bridge
- Shear beam and platform cells, for frames that sit the bridge on top
- Bending beam cells, including our own
- Bellows cells, sealed for wet and washdown conveyors
- Stainless steel and alloy aluminium bodies
Capacities
- Metric: 50, 75, 100, 150, 200, 250, 300, 500, 750, 1000, 1500 and 2500kg
- Imperial: 100, 150, 200, 250, 300, 500, 750, 1000, 1500, 2000 and 2500lb
- One, two or four cell weighers all supplied as matched sets
- Other capacities to order
What goes with them
- Rod ends in M8, M12, 5/16 and 1/2 inch
- Tie rod kits in M12, M16 and M20
- Clevis blocks, reducers and extensions
- Spherical washer sets and ball and cup assemblies
- Our own load cell switching junction box, in a stainless IP65 enclosure
Accurate Industries load cells
We supply two of our own families, made to our specification and serial numbered, so we can trace any cell we have supplied back to its certificate years later. Both carry the same electrical specification.

The two families are not interchangeable. Tell us the weigher and we will confirm which one suits before you order.
Read every load cell without pulling a single wire
On a multi cell weigher the hard part of a load cell fault is not fixing it, it is finding which cell is at fault. Normally that means opening the junction box and disconnecting cells one at a time, in the weather, with the conveyor down.
Our load cell switching PCB replaces the standard junction box and lets a technician switch to each cell in turn and read it on its own, without disconnecting anything. It comes fitted in a stainless steel IP65 enclosure, in one and four cell versions, and it suits any make of weigher because it sits between the cells and the integrator.
It is the difference between a diagnosis that takes ten minutes and one that takes a shift, and it is worth fitting before you need it rather than after.
Cells for the weighers we maintain, and for the ones we have never seen
Between them, the belt weighers we look after around the country carry every mounting style and nearly every capacity made, so for our own customers a replacement cell is usually already on file. If we have never been to your site that changes nothing: a load cell is defined by its capacity, type, rated output and wiring rather than by the badge on the weigher, so tell us those and we can match it.
Belt weighers we regularly supply replacement load cells for include:
Five things off the old cell and we can match it
Most of what we need is stamped on the cell itself or printed on the label. A photo of the cell and its label answers most of this in one go.
- 1Capacity
The rating stamped on the body, in kg or lb.
- 2Type and mounting
S type, shear beam, bending beam or bellows, and how it is held: rod ends, clevis, or bolted flat.
- 3Rated output
The mV/V figure on the label, usually 2 or 3.
- 4Number of cells
One, two or four on the weigher, so we can supply a matched set.
- 5Cable and wiring
Cable length you need, and whether the weigher is wired four wire or six wire.
If we already maintain the weigher, you only need to tell us which conveyor: the cell details are on file from the last calibration. If you are not sure of any of it, send a photo of the cell and its label and we will work it out.
Send us a photo of the cellWe supply the part that gets it working again
Plenty of the belt weighers on Australian sites are older than the companies that made them. When the original cell is no longer made, that is usually where the conversation with the original supplier ends.
It is not where ours ends. We supply the parts to get a weigher working again, like for like where the part still exists and a sound equivalent where it does not, and we will tell you honestly which one you are getting. Where a weigher has reached the end of its life we will say so and quote the replacement, because a machine that needs a repair every shutdown is costing more than it looks.
Need load cells? Give us a call
We supply load cells and weighing equipment across mining, food and other industries, and in most cases what you need is already on the shelf or a quick turnaround. Tell us what you have, or send a photo of the label, and we will sort out the rest.
Load cell frequently asked questions
Can you supply a load cell for any make of belt weigher?
In nearly every case, yes. A load cell is defined by its capacity, its type and mounting, its rated output and its wiring rather than by the badge on the weigher, so if you can tell us those we can supply a cell that fits. Send a photo of the cell and its label if you are not sure.
How do I know which load cell has failed?
With the belt empty and stopped, measure the excitation across each cell and then its signal output. A cell reading far from the others, a signal that will not settle, or an insulation reading down in the megohms rather than the thousands of megohms all point at that cell or its cable. Water in a junction box gives very similar symptoms, so check that before condemning a cell. Our guide to belt weigher load cells walks through the checks in order.
Do I have to replace all the load cells at once?
On a multi cell weigher it is usually best to. Cells share the load, so a new cell of a slightly different sensitivity sitting beside three aged ones gives you a weigher that reads differently depending on where the material sits across the belt. If budget means replacing one, tell us the others so we can match the new cell to them as closely as possible.
What does C3 mean on a load cell?
It is the accuracy class the cell was made and tested to, covering how closely it follows the load through its range, how well it returns to zero and how much it drifts with temperature. C3 is the class normally used for belt weighers and it is what our own cells are rated to. It describes the cell, not the weigher: a C3 cell in a worn weigh frame still gives a poor result.
Does the load cell come with a certificate?
Yes. Every cell we supply comes with its test certificate showing rated output, zero balance and the resistance readings for that cell. We record the serial number of every cell we supply against the weigher it went into, so we can produce the certificate again years later.
Do you supply the mounting hardware as well?
Yes. Rod ends, tie rod kits, clevis blocks and reducers, spherical washer sets and ball and cup assemblies, and the junction boxes that go with them. Worn mounting hardware causes load cell symptoms often enough that it is worth changing while the weigher is open.
What is a load cell switching junction box?
It is our own board, fitted in place of the standard junction box, that lets a technician switch to each load cell in turn and read it on its own without disconnecting anything. On a four cell weigher that turns finding a faulty cell from an hour of pulling wires apart in the weather into a couple of minutes with a multimeter. It comes in a stainless steel IP65 enclosure, in one and four cell versions, and it suits any make of weigher because it sits between the cells and the integrator.
