We would not be able to survive the ups and downs of the economy and ruining our reputation by selling cheap products that don't last.

Frequently asked questions

A loadcell is the heart of any scale. Inferior metals, combined with un-tested and unstable strain gauges within these loadcells 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 loadcell with a ZEMIC LOADCELL. 

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

Digital loadcells :
*These have an Analogue to Digital convertor attached to the body or inside the loadcell. 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 loadcells 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 loadcell can withstand before ingress (leakage) inside the loadcells.

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.
