Yes, we service that belt weigher brand too

We’re an independent belt weigher service and calibration company, not tied to any one manufacturer. The bigger brands have their own guides. This page covers the rest: how we handle a brand we haven’t met, the other makes we see on Australian sites, and what a calibration looks like whatever the badge. For what happens on the day, see what happens during a calibration visit.

How do we handle a brand we haven’t worked on?

A belt weigher multiplies the load on the weigh idlers by the belt speed to give a rate in t/h and a running total. Learn the four parts on one brand and you know them on all of them. What changes between makes is the menu layout, the terminology and the wiring. So when we meet an unfamiliar scale, we don’t guess. We work in the same order every time:

1. Record the as-found settings and readings before we touch anything.
2. Check the speed input is reading correctly.
3. Check the load signals back at the frame. On makes that use LVDTs (displacement sensors that read how far the frame moves under load), check they’re still aligned in their clamps.
4. Calibrate zero and span against known references.
5. Record the as-left state and hand over a report.

Which other brands do we see in the field?

These are the makes without their own page that we run into on Australian sites and hold documentation for. We name them at brand level. We don’t claim model-by-model experience on gear we haven’t had our hands on.

• Merrick: American belt scales and weigh belt feeders.
• Mantraweigh: British weighing indicators and controllers. It usually turns up as the electronics end of an installation rather than a whole weigh frame.
• Archweigh: American belt scales and integrators from a bulk conveyor components maker.
• Nuweigh: Australian-built belt weighers, alongside weighbridges and industrial scales.
• Precia Molen: French belt weighers and weigh feeders. The i40 BS and I400 have their own guide.
• Instrotech: Australian-made weighing electronics: the indicators and transmitters that run a belt weigher off the load cell signals.
• Flowforce: Australian-supplied bulk weighing gear: belt scales, impact weighers and solids flow meters.

Your brand isn’t on the list?

Ask anyway. The list is the brands we happen to name, not the limit of what we service. An unfamiliar integrator gets the same treatment as any other: we read what it’s doing now, prove the speed and load signals on their own, and calibrate against known references rather than trusting the number on the screen.

Whatever the badge, we cover the whole scale, not just the box on the wall:

• Weigh frames and their mechanicals: pivots, tie rods and mounts.
• Load cells, LVDTs and their field wiring.
• Speed sensors of every type.
• Integrators and indicators, whatever the make.
• Calibration: zero, span, and a material comparison where it’s warranted.
• Fault-finding and repairs on ageing units.

We supply parts for these brands and the other major belt weigher brands: a genuine part where it’s available, or a suitable alternative, with compatibility confirmed and the part identified on the quote.

If a scale is so specialised, or so locked into a proprietary system, that we can’t do it justice, we’ll tell you and point you elsewhere. We won’t learn on your dollar.

What does a calibration look like, whatever the brand?

1. Zero on a clean, empty belt over whole belt revolutions, so variation around the belt averages out.
2. Span against a known reference: static test weights or a calibration chain on the frame.
3. Material comparison where it’s warranted and practical: the belt weigher total against a known trucked or weighbridge figure. The two rarely agree exactly, so we look at the size and direction of the gap. See belt weigher vs weighbridge.

The numbers we work to: repeat span runs within about 0.1%, and a routine span that has moved more than about 0.25% needs attention. Your integrator’s own limits are in the manual for your model.

Who adjusts what. On our service visits we adjust the zero and span when the checks show it’s needed. Between visits, site should run a zero about every two weeks and after a big change in the weather, and check the span but record it rather than accepting it. We recommend a service calibration every quarter so the scale keeps up with the seasons.

We record as-found figures before we change anything and as-left figures after. They go into AIMM, our asset management system, so every scale we look after has a permanent record and a due date you can see, whatever the brand, at no extra cost.

Need a manual for your equipment?

On a less common brand, the badge and model on the integrator, the software version on its start-up screen and a photo of the weigh frame tell us most of what we need.

Talk to us about manuals for your equipment. Send the make, model, serial number and software version (a photo of the label is fine) and we’ll help you find the right document.

When should you call us?

Call when you’ve got a scale nobody on site knows, when the settings or service history have been lost, or when the numbers stop making sense and the usual checks haven’t found why. Tell us the badge and roughly what it’s doing, and we’ll tell you honestly whether we can help. Call 1300 101 666 or email admin@accurateindustries.com.au, or see booking a belt weigher service.
