Nexus

NEXUS is a series of impedance sensors designed to measure phase concentration in a wide variety of applications, from fundamental research to industrial R&D and process control.

NEXUS sensors are compact and full-featured yet easy-to-use, offering benefits usually found only in larger and more expensive analyzers. We offer our customers different versions, which are adapted to the different fields of application.

The series uses advanced hardware and flow models for fluid characterization solutions. Designed for process monitoring and quality control of industrial liquids in production plant environments.

Impedance Sensors

Nexus Sensors use two impedance probes to measure one or multiple electrical properties of the test volume (pipelines, reaction chamber) with a very high time resolution under extreme operating conditions.

With the help of these probes, it is possible to record temporal phase fractions, flow velocities, and structure sizes with a time resolution of 10 ksample/s on both channels.
