Field of application
The process transmitter Nivotester FTR525 is used in conjunction with the microwave barrier Soliwave FQR57/FDR57 for detection of point levels and bulk flow (flow / no flow, trend). The microwave barrier is also suitable for detecting and counting objects, detection of deposits as well as monitoring of filling processes and material transfer points. It can be installed in containers, conduits, hoppers, filling stations, shafts, filters or on free fall shafts.
Non-contact (wear- and maintenance-free) limit detection (min/max) and flow monitoring (flow/no flow, trend) for bulk solids.
Detecting, counting and positioning of objects
Detection and analysis of deposits and contamination in filters
Monitoring of filling processes
Monitoring of material transfer points
For high temperature applications up to 450°C (+842°F)
For high pressure applications up to 20bar (+290psi)
International explosion protection certificates
Benefits
Simple und comfortable menu-guided operation via display and keysDifferent adjustment functions (automatic or manual) with clear graphic representation of the set detection range and the current signal strength Up to 5 different channels can be set for parallel operation of several microwave barriers which are installed in close proximity to each other Offers functions for application analysis Provides many adjustment possibilities such as damping, selectable switch-on and switch-off points as well as switch-on and switch-off delays Easy installation due to compact housing for easy mounting on standard top-hat rail and wiring via pluggable terminal block connectors High level of operational safety through line monitoring up to the sensor
