IPP 70-Se – standard ATEX probe
The IPP 70-Se is the intrinsically safe version of the standard model IPP 70-S for use in processes with ATEX requirements.
When used in conjunction with a measuring PC, it allows for the determination of particle size distribution (e.g., Q0, Q3) as well as the attributes of the distribution (x10, x50, x90, etc.) even directly within processes in ATEX zones 0/20 (gas/dust).
It consists of a robust stainless-steel construction with sapphire windows to protect the optics from wear.
Its dimensions, measuring ranges and accessories make it compatible with all other probe models, so all of the accessories for process adaptation can also be used with the IPP 70-Se in ATEX areas.
Compressed-air-driven accessories, such as dispersers, ensure that the measuring volume and measurement optics are kept permanently free from contamination while also guaranteeing optimal adaptation to process and particle attributes. The probe is therefore also suitable for use in processes with damp and sticky particles. Using a disperser means that measurements can also be taken in processes with irregular particle movement, such as in fluidised beds, or processes with high particle loads, such as high-shear processes.
A complete measuring system consists of the IPP 70-Se with accessories for process adaptation, the barrier box for Ex-zone separation and a measuring PC with measuring program for particle searching and the calculation of all distributions. The measured results can then be made available to a higher-level control system via optional interfaces.
