Products for Hazardous Areas

Equipment and products operating in hazardous areas are required to meet stringent criteria. They must be 'protected' to avoid the possibility that they could become a source of ignition. Weighing systems are often an integral part of a process within the hazardous area and therefore must have suitable protection.

Thames Side Sensors, as a manufacturer and supplier of weighing equipment, complies with the ATEX equipment directive 2014/34/EU. We are a market leader in the design and manufacture of load cells for weighing in hazardous areas, having developed a range of load cells, junction boxes and weight indicators/electronics specifically designed for such demanding applications, for example chemical weighing.

Load Cells and Weighing Assemblies

• All our ATEX approved load cells have certification to ATEX Ex ia IIC T6 for all gas zones 0, 1, 2 and all dust zones 20, 21, 22.
• Several models have certification to ATEX Ex ta IIIC, allowing use in all dust zones 20, 21 and 22 without safety barriers.
• Others have certification to ATEX Ex nAT6, allowing use in gas zone 2 without safety barriers.
• All our ATEX approved load cells are PESO certified by Chief Controller of Explosives (CCOE) having Approval No: A/P/HQ/MH/104/5943 (P424399).

Models T95, MasterMount and VC3500 have dual ATEX and IECEx certification to Ex ia IIC T6 Ga, Ex ia IIIC T70°C Da, allowing them to be used by OEMs and system integrators to supply systems with load cells having dual certification. 

Weighing Instrumentation

Load cells form only part of a weighing system. If located in a hazardous area, the junction box and weight indicator / transmitter will also require ATEX certification. However, if the junction box and/or indicator are located in a safe area, there is no need for them to be ATEX certified - only the load cells will need this. Depending on the ATEX/IECEx certification of the load cells, safety barriers may or may not be required.

Thames Side can supply high quality junction boxes for use in ATEX zones 0, 1, 2, 20, 21, 22 and trusted, reliable weight indicators for use in ATEX zones 1, 2, 21 and 22.
