OXEA® Online Series

Online X-ray Elemental Analyzers since 2002 – multi patented technology

no nuclear measurement – no nuclear waste – no countermined material

The OXEA® product line is based on X-ray fluorescence (XRF) and determines the elemental composition of the measured product. Indutech has modified the well known XRF technique, for online applications. All elements with an atomic number > 10 (Sodium and above) can be detected down to the ppm-range.

The OXEA® is applicable for all materials and can be used on the main conveyor belt and at any kind of bypass. The sensor box is easy to install in any applications.

The OXEA® was at first mainly used in power stations to determine the BTU, sulphur and ash content of coal and gives a high level of accuracy obtainable with online analyzers. In the meantime OXEA® is also used for a large variety of non-coal applications. OXEA® is protected by several worldwide patents.

This device is also available as explosion-proof versions for zone 21 or 22.

Remote Service 
Remote service can be provided through internet connection for quick customer support, available for all devices. This saves time and money.

New Development special pneumatic lifting

To make maintenance easy and in an extreme short time, a pneumatic lift was developed with self adjustment of the OSB. This allows to lift the OSB pneumatically. In the service position the service door can be opened to get access to the X-ray tube and the detector system. Additionally the OSB can be manually turned by 90 degrees to check the bottom opening for the X-rays, and to clean it, if necessary. Furthermore the service position is a safe position, which can be selected in case of abnormal conditions, such as extremely overload on the belt.

The modularity of the OXEA® Systems:
allows a very easy adaption to the multifarious process conditions and requirements, e.g. at main belt, bypass belt, chute or other bypasses.
