MEX-3.2 Explosion Multisensor
Applications:
- an element of the protection system for vessels and process equipment where flammable and combustible substances are handled in explosive concentrations,
- identification of explosion pressure rise, in its early stages, triggers the activation of the explosion protection system,
- designed for assembly on process vessels, ducts and pipelines in which ST1-ST3 class dusts are present as well as for gases and hybrid mixtures across all industries.
