NEMESIS developed an innovative weighing technology, the EasyWeigh® system, at the state of the art in dynamic weighing sector and installed on all our machines.
EasyWeigh® technology allows to overcome all the problems usually related to the commonly used “peak weight” technology, largely enhancing the accuracy and the solidity of our checkweighers.
This week we’d like to share with you a 5-steps little insight about EasyWeigh®, its features and the advantages it has.
Let’s start with a first gaze on what we were trying to get rid of when we start designing EasyWeigh®.
What is the “peak weight” technology?
Most of checkweighers’ manufacturers use the “peak weight” algorithm in their products.
This technology, in brief, measures the weight value at the “peak” part of the signal coming from the load cell.
“Peak weight” technology:
- requires the user to perform laborious and time-wasting operations, as the calibration for each product and the constant check of the machine’s performances. Moreover, when changing the weighted products, various tests and setups are required, including the check of the “zone of indecision” (ZOI) – to confirm the correct operation of the machine – or the reset of the parameters, in order to be sure that the detected conforming weights stay within the predetermined thresholds;
- is badly affected, in its weighing accuracy, by air currents, temperature variation and vibrations;
- requires to find a correction factor to align static and dynamic measurement results;
- gives certified weighing results only for the specific products showed in the machine’s metrological plate (see Fig. 1).

Tomorrow we’ll continue our insight about EasyWeigh® technology by showing its advantages in terms of certification and freedom from calibration / learning procedures.
