What does OIML stand for?

The majority of the products manufactured by Zemic and therefore the weighing prodcuts and loadcell models Richter Scale offer for sale are genuine OIML approved products.

The International Organization of Legal Metrology (OIML) is an intergovernmental treaty organization which develops model regulations, standards and related documents for use by legal metrology authorities and industry, provides mutual recognition systems which reduce trade barriers and costs in a global market, represents the interests of the legal metrology community within international organizations and forums concerned with metrology, standardization, testing, certification and accreditation, promotes and facilitates the exchange of knowledge and competencies within the legal metrology community worldwide, cooperates with other metrology bodies to raise awareness of the contribution that a sound legal metrology infrastructure can make to a modern economy.of the economy and ruining our reputation by selling cheap products that don't last. Buying an industrial scale that will stand up to the rigours of the local market and operators requires careful and fully informed research.

Legal Metrology Accredited

We are an NRCS and SANAS accredited Verification body and Repair body under the Legal Metrology Act and Legal Metrology Regulations. Our products are type approved for trade use / prescribed purpose and thus carry the NRCS stamp of quality and excellence, giving you the confidence that you will get a product that meets a standard of quality and reliability which is traceable to international metrology and quality standards.

Frequently asked questions

More Information

A load cell is the heart of any scale. Inferior metals, combined with un-tested and unstable strain gauges within these load cells mean that these cannot perform consistently in various conditions, temperatures or even during simple repeatability testing by the untrained operator! Look for a trusted brand with quality materials and a supplier like us with direct factory backing and guarantees. Beware of copies and imitations. If it’s not sourced from Richter Scale there is a chance it could be a copy or model made for entry level domestic use.

First check if the scale/weighing system is for trade/prescribed purpose or not? If they are then 99/100 times you will have to replace with the same make and model.

Non trade applications - if the size and hole patterns fit then you are free to substitute your current load cell with a ZEMIC LOAD CELL. 

Analogue load cells :
*Sends mV via the signal lines to the instrument which has an Analogue to Digital convertor.
*Easy to substitute and replace with other manufacturers.
*Cheaper.

Digital load cells :
*These have an Analogue to Digital convertor attached to the body or inside the load cell. It then sends RS422/485 to the indicator.
*More expensive
*Less/no compatibility with other manufacturers.
*Protocol locked.

The strain gauges and body/element material of the same brand load cells between these 2 technologies remain the same.

It is only on the digital conversion side where they differ in technology.

Areas or sites with potentially hazardous or explosive environments require weighing equipment which has EX ratings. Many of our Alloy and Stainless steel loadcells are available in an EX version. These should be paired with EX rated junction boxes and EX rated instrumentation.

Dusty and/or wet/corrosive applications call for greater protection against dust and moisture. IP ratings vary from IP65, IP66, IP67, IP68, IP69

These levels and numbers indicate the level of exposure and/or submersion in water and exposure to dust which the load cell can withstand before ingress (leakage) inside the load cells.

Hazardous-area system guidance

EX Load Cell and Junction Box Guidance

Hazardous-area weighing requires the correct load cell, junction box, wiring method and site classification before equipment is selected.

01

Typical industries

Chemical plants, grain handling, fuel storage, paint production, mining, food dust areas and any zone with explosive gas or dust risk.

02

Selection checks

Confirm zone classification, gas or dust group, temperature class, barrier requirements, cable glands and the approval documents needed on site.

03

System approach

The load cell is only one part of the EX system. Junction boxes, barriers, indicators and wiring must all suit the hazardous-area design.

04

Documentation

Keep certificates, wiring diagrams and installation records with the site file for inspection and maintenance.

05

Installation caution

Do not substitute standard cells, glands or boxes into an EX installation without approval from the responsible engineer.

06

Maintenance

Inspect glands, seals, earth bonding and enclosure condition during service visits.

PRODUCT FAQ

Common Questions

Can I use a normal junction box in an EX area?

No. The junction box and wiring method must match the hazardous-area requirements.

What information is needed for a quote?

Zone, gas or dust classification, capacity, number of cells, instrumentation location and any certificate requirements.
