At-line monitoring of the phosphating process

The quality of a phosphated metal surface directly depends on the composition of the phosphating baths (pH, conductivity, acidity, alkalinity, fluoride and zinc)

The quality of a phosphated metal surface directly depends on the composition of the phosphating baths (pH, conductivity, acidity, alkalinity, fluoride and zinc).

Because the constant loss of bath reagents or contamination of the rinsing baths it is very important to constantly monitor these agents.

Keeping the consumption of phosphating agents as low as possible can optimise costs.

In a modern factory you find many different types of baths.

It is very difficult to keep an eye on every single parameter.

ProcessLab will monitor these by itself and, if desired, transmit the data to any suitable process control system (PCS).

Alarm criteria can be set as well as external signals like a flashing alarm lamp.

ProcessLab can, with the help of barcodes, automatically recognise the sample and the parameter which have to be analysed.

Place any sample on ProcessLab, register it and hit the "Start" button.

All you get is the result at the desired place, like a report or a simple pdf, custom-designed for the particular needs of the process.

The described ProcessLab at-line analysis system controls, records and documents the important analytical parameters of the entire phosphating process.

The combination of the analytical methods involved as well as the intuitive handling via the well-arranged user interface allow for complete process control.

Features/general information.

All 6 parameters in one system and monitored on demand.

OneButton analysis.

Very easy to operate for semi-skilled staff.

One sample cycle includes preparation of Dosino, rinsing, sampling and measuring.

Barcode reader offers automatic method selection.

Optional liquid level sensors monitor the reagent level and advice.

ProcessLab to wait for manual intervention if necessary.

Additional terminals for the I/O controller allow an external communication like transmission of a result to a PCS.

An "out of limit" alarm can be set and any external device will be switched on.

This system is very flexible and can be adapted very easily to any specific needs.

If necessary an additional reagent cabinet is available and placed directly under the ProcessLab module.

It has sufficient space for all reagents and makes ProcessLab even more comfortable.
