What is a weighing indicator?

A load cell is the sensor in a scale that registers the weight. Inside the load cell is a strain gauge: a small resistor that changes as the load cell deforms.

This is how it works:

• A small electrical signal goes into the load cell, for example 10 millivolts.
• When you place weight on the scale, the load cell bends very slightly.
• As a result, the resistance increases and a smaller signal comes back, for example 5 millivolts.
• Thanks to calibration, the indicator knows which weight corresponds to that signal, for example 5 kilos.

In a scale, the load cell is often positioned between a bottom plate and a top plate. These plates do not touch each other; all the weight passes through the load cell.

For most companies, a complete scale is the best choice. Around 95% of our customers opt for this: everything is matched, the scale is ready to use straight away and you don't have to figure anything out yourself.

Separate load cells are mainly of interest to machine builders or companies that build their own weighing system. They purchase load cells with matching mounting kits and an indicator, and assemble a system themselves.

A common application is weighing a silo or liquid tank. The tank is placed on the load cells, so you always know exactly how much weight it contains. Not sure which route suits you? We are happy to think along with you.
