The Minicap FTC262 cable probe has a simple structure, is economical and practical, and is used for limit detection of bulk solids, especially for corrosive media or media with heavy buildup. The probe is specially designed for limit detection of light bulk solids. Typical applications: grain, flour, milk powder, animal feed, cement, talc or gypsum.
Advantages
The measuring system consists of the probe and electronics:
——easy installation
——no calibration at startup
Built-in buildup compensation:
——precise switching action is maintained even with heavy probe buildup
——high operational safety
Robust mechanical parts:
——no wearing parts
——long service life
——maintenance-free
The Minicap FTC262 cable probe can be shortened
-optimized length to match the measuring point in the silo
-reduced inventory
Areas of application
Minicap is specially designed for limit detection of light bulk solids with a maximum particle size of 30mm and a dielectric constant of εr ≥ 1.6. Typical applications: grain, flour, milk powder, animal feed, cement, talc or gypsum.
Model:
Minicap FTC262: with cable probe up to 6 meters long, for bulk solids measurement
Relay output with AC or DC power supply (spare auxiliary changeover power/SPDT)
PNP output with 3-wire DC power supply
