Weightron provide a wide range of ATEX (Ex) certified load cells, weight indicators and industrial scales for hazardous area weighing.

Weighing systems for hazardous areas

Weightron provide a range of ATEX certified load cells and weight indicators, suitable for ATEX weighing in zones 1,2,21 and 22 (gases and dusts). Installation of weighing systems in designated hazardous areas must be carried out by suitably qualified personnel.

The D440 ATEX certified weight indicator offers a wide range of features and can be used in hazardous areas for both gases and dusts.

The D440 can operate directly in the hazardous area, without the need to install additional galvanic barriers into the safe area. This not only saves installation costs but also gives a much neater and more professional installation.

The D440 has a single and double weighing function and can be configured for simple dosing or filling applications. The 18 key alphanumeric keypad facilitates set up and operation, and the unit comes as standard with four electro-mechanical relay outputs, four opto-isolated inputs and two bi-directional optical-fibre serial channels. An optional voltage or current analogue output is also available.

What is ATEX?

ATEX is the name commonly given to the two European Directives for controlling explosive atmospheres:

1) Directive 99/92/EC (also known as ‘ATEX 137’ or the ‘ATEX Workplace Directive’) on minimum requirements for improving the health and safety protection of workers potentially at risk from explosive atmospheres. The text of the Directive and the supporting EU produced guidelines are available on the EU-website. For more information on how the requirements of the Directive have been put into effect in Great Britain see the information in the section on Equipment and protective systems intended for use in explosive atmospheres.

2) Directive 94/9/EC (also known as ‘ATEX 95’ or ‘the ATEX Equipment Directive’) on the approximation of the laws of Members States concerning equipment and protective systems intended for use in potentially explosive atmospheres. The text of the Directive and EU produced supporting guidelines are available on the EU website.
