PIOX® R is FLEXIM's new process refractometer sensor. This long sensor version can be mounted on pipes and vessels with different process connexion systems.
The unique tranmitted light measurement reaches a high precision, is thermically driftfree and zero point stable. An integrated Pt1000 probe cares for a rapid temperature compensation.
Standard refractometer applications such as the calculation of the sugar concentration in °Brix are included in the standard delivery. Customer specific fluid data can be implemented with the help of the software tool RMKoeff. Afterward, PIOX will determine the customer specific output quantites such as for exemple the mass concentration of a component of a solution. When further process parameters are input, the measurement of 3-component mixtures is also possible.
The refractometer offers various useful tools for rapid error detection, amongst other n internal self-diagnosis as well as a possibility to detect coating formation on the prism.
PIOX® R400 can be used in the most diverse applications. Various designs, materials and process connection guarantee optimum process integration. To meet the special requirements of the chemical industry, versions for use in explosive atmospheres from ATEX zone 2 to ATEX zone 0 are available. |
