The Nivotester FTR525 process transmitter is used together with the Soliwave FQR57/FDR57 microwave barrier for limit detection and bulk solids flow detection (non-zero flow/zero flow, flow trend). The microwave barrier can be used for detection and counting, detection of deposits, and monitoring of the feeding process and material transport quantity. It can be installed in vessels, channels, on stockpiles, at feed stations, in pumping stations, in filters or in other free-fall shafts.
Advantages
Simple, convenient menu-guided operation via the display unit and operating keys
Various adjustment functions (automatic or manual operation), clear graphic display of the set detection range and current signal strength
Up to 5 different channels can be set to operate several microwave barriers installed side by side simultaneously
Application analysis functions available
Various adjustment functions such as damping time, selectable switch-on and switch-off points, and switch-on/switch-off delay times
Compact housing for easy installation, conveniently mounted in-line on a standard top-hat rail and wired via pluggable terminal blocks
Online monitoring including the sensors ensures high operational safety
Application
Non-contact (wear-free, maintenance-free) limit detection (low/high limit) and flow monitoring (non-zero flow/zero flow, flow trend) of bulk solids.
Provides detection, counting and positioning functions
Detects and analyzes deposits and contaminants in filters
Monitors the feeding process
Monitors the material transport quantity
Suitable for use at maximum temperatures not exceeding 450°C (+842°F)
Suitable for use at maximum pressures not exceeding 20 bar (+290 psi)
International explosion protection certification
