On-site scale maintenance

A scale rarely breaks down all at once. It gradually weighs worse: dust under the platform, a sunken foot, a hardened seal, a load cell that was overloaded once. Maintenance catches this before it becomes a measurement error or a breakdown.

Why maintenance pays off

You cannot see a measurement deviation on the display. A scale that weighs half a percent too high gives away a little product every day, or rejects batches that were fine. And a scale that is out of action holds up a line or a loading bay. Maintenance is the service that prevents repairs and failed calibrations.

What a maintenance visit includes

• cleaning, including under the platform and around the load cells;
• levelling and checking the structure, feet and mounting;
• checking load cells, cabling, connections and the power supply or battery;
• checking seals on scales that are cleaned wet;
• going through the settings and the connection with a printer, PC or control system;
• measuring with test weights what the instrument does across the whole range, including in the corners;
• adjusting where necessary, and recording what was measured.

Anything worn or damaged is replaced with original parts. If there is more going on, you hear about it first, with a price.

For which scales

We maintain all the weighing equipment we carry: floor scales, pallet scales, bench and counting scales, laboratory balances, weighing indicators and weighing systems, and weighbridges. A scale drifts faster especially where weighing is heavy, wet or dusty.

On site, in one visit

Maintenance takes place where the scale stands. The engineer brings the test weights that match your weighing range; we have our own transport for heavy weights. If there are several scales at one location, we do them in the same visit. Delicate work on an analytical balance can also be done in our workshop.

How often is maintenance needed?

There is no interval that applies to all scales. It depends on the type of instrument, how intensively you use it, where it stands - wet, dusty, cold, vibrating - and what a measurement error would cost you. Once a year, together with the calibration, is a common starting point. We help you determine the interval and keep track of when the next visit is due; if you want it done periodically, mention this in your request.

Maintenance, calibration and re-verification together

Maintenance usually goes hand in hand with calibration with a certificate: the same appointment, the same engineer. If a verified instrument then needs re-verification, the re-verification is arranged through the manufacturer and planned around the visit. That way the instrument is out of use as little as possible.

What you can do yourself

Between two visits, daily care makes the biggest difference: keep it clean, do not overload it, do not drop it and check regularly with a check weight that it is still correct. How to do this is explained in scale maintenance and cleaning.

Signs that maintenance is needed

• the same weight gives a different result twice;
• the scale no longer returns neatly to zero, or drifts;
• a load weighs differently in the corner than in the centre;
• the platform wobbles, is not level or is damaged;
• a cable or connection is loose or damaged;
• the battery does not last as long as it used to.

If you notice any of these, plan a visit before it turns into a breakdown.

Maintenance in wet and hygienic areas

Scales that are hosed down daily, such as in meat processing, dairy and fish processing, need extra attention for the seals, cable glands and the junction box. A seal that has hardened or is damaged lets moisture in, and moisture in a load cell is one of the most common causes of a deviation. Which IP rating and which stainless steel belong in which area is explained in stainless steel scales for wet and hygienic areas.

Request maintenance

Call +31 345 786 553, email sales@weegexperts.nl or use the form on this page. Tell us which scales they are and where they are:

• make and model - a photo of the type plate is enough;
• the serial number and the weighing range;
• whether it carries the green M mark;
• what you notice, or what you need;
• where the instrument is, and whether it can be moved.

You then receive a price and a proposed schedule in advance. For a fault, see repair.

Frequently asked questions about maintenance

Can my scale be maintained on site?

Yes, that is the normal approach. The engineer brings the test weights that match your weighing range. Delicate work on an analytical balance we prefer to do in the workshop.

How often should a scale be maintained?

That varies by instrument and use. Once a year, together with the calibration, is a common starting point; more often with heavy use or in a wet or dusty environment.

What is the difference between maintenance and calibration?

Maintenance is preventive: cleaning, checking and staying ahead of wear. Calibration is measuring and recording how far the scale deviates, in a certificate. We usually do both in the same visit.

Do you also maintain scales from other brands?

Often, yes; checking and measuring is possible on almost any instrument. Whether parts can be replaced depends on the brand. We tell you in advance.

What does maintenance cost?

That depends on the number of scales, the weighing range and where they are. You get the price in advance; more scales in the same visit lowers the cost per instrument.

Do you keep track of when the next visit is due?

Yes. We help you determine the interval and keep track of when the instrument is due again.
